This moisture analyzer complies with
the European Council Directives as
well as international regulations and
standards for electrical equipment,
electromagnetic compatibility, and the
stipulated safety requirements.
Improper use or handling, however,
can result in damage and/or injury.

Read these operating instructions
thoroughly before using your moisture
analyzer to prevent damage to the
equipment. Keep these instructions in
a safe place.

Follow the instructions below to ensure
safe and trouble-free operation of your
moisture analyzer:

! Use the moisture analyzer only for

performing moisture analysis of sam­ples. Any improper use of the analyzer
can endanger persons and may result
in damage to the analyzer or other
material assets

! Do not use this moisture analyzer in a

hazardous area/location; operate it only
under the ambient conditions specified
in these instructions

– The moisture analyzer may be operated

only by qualified persons who are
familiar with the properties of the
sample to be analyzed

! Make sure before getting started that

the voltage rating printed on the
manufacturer‘s label is identical to your
local line voltage (see the section on
“Connecting the Moisture Analyzer to
AC Power” in the chapter entitled
“Getting Started”)

– The device comes with a power supply

that has a grounding conductor

– The only way to switch the power off

completely is to unplug the power cord

– Position the power cable so that it

cannot touch any hot areas of the
moisture analyzer

– Use only extension cords that meet

the applicable standards and have a
protective grounding conductor

– Disconnecting the ground conductor

is prohibited

– Connect only Sartorius accessories and

options, as these are optimally designed
for use with your moisture analyzer

– Protect the moisture analyzer from

contact with liquid

– If there is visible damage to the

moisture analyzer or power cord:
unplug the equipment and lock it in a
secure place to ensure that it cannot
be used for the time being

! Clean your moisture analyzer according

to the cleaning instructions only
(see “Care and Maintenance”)

Do not open the analyzer housing.
If the seal is broken, this will result in
forfeiture of all claims under the
manufacturer’s warranty.

In case you have any problems with
your moisture analyzer:

$ contact your local Sartorius office,

dealer or service center

Warning: Severe Burns!

– When setting up the moisture analyzer,

leave enough space to prevent heat
from building up and to keep your
analyzer from overheating:
– leave 20 cm (about 8 inches) around

the moisture analyzer

– 1 m (3 ft.) above the device

– Do not put any flammable substances

on, under or near the moisture analyzer,
because the area around the heating
unit will heat up

– Be careful when removing the sample

from the chamber: the sample itself,
the heating unit and the sample pan
used can still be extremely hot

– Do not remove the heating unit during

operation: the heating element and
its protective glass panels can get
extremely hot!

– Prevent excess heat build-up around

the analyzer

Hazards for persons or equipment
posed by using specific samples:

Fire Explosion

– Flammable or explosive substances

– Substances that contain solvents

– Substances that release flammable

or explosive gases or vapors during the
drying process

In some cases, it is possible to operate
the moisture analyzer in an enclosed
nitrogen atmosphere to prevent the
vapor released during drying from
coming in contact with oxygen in the
surrounding atmosphere. Check on a
case-to-case basis whether this method
can be used, because installation of the
analyzer in too small an enclosed space
can affect its functions (for instance
through excessive heat build-up within
the analyzer). When in doubt, perform
a risk analysis.

The user shall be liable and responsible
for any damage that arises in connec­tion with this moisture analyzer.

Poisoning Caustic burns

– Substances containing toxic or caustic

or corrosive substances: These may
be dried only under a fume hood. The
value for the “lower toxic limit“ in a
work area must not be exceeded.

Corrosion:

– Substances that release aggressive

vapors during the heating process
(such as acids): In this case we recom­mend that you work with small sample
quantities. Otherwise, vapors can
condense on cold housing parts and
cause corrosion.

The user shall be liable and responsible
for any damage that arises in connec­tion with this moisture analyzer.

6 different languages

Installation Instructions

The moisture analyzer is designed to
provide reliable results under normal
ambient conditions in the laboratory
and in industry. When choosing a
location to set up your moisture
analyzer, observe the following so that
you will be able to work with added
speed and accuracy:

– Set up the moisture analyzer on a

stable, even surface that is not exposed
to vibrations

– Avoid placing the analyzer in close

proximity to a heater or otherwise
exposing it to heat or direct sunlight

– Avoid exposing the moisture analyzer to

extreme temperature fluctuations

– Protect the moisture analyzer from

drafts that come from open windows
or doors

– Keep the moisture analyzer protected

from dust, whenever possible

– Protect the moisture analyzerfrom

aggressive chemical vapors

– Do not expose the analyzer to

extreme moisture

– Make sure to choose a place where

excessive heat cannot build up. Leave
enough space between the moisture
analyzer and materials that are affected
by heat.

Conditioning the Moisture Analyzer

Moisture in the air can condense on the
surfaces of a cold moisture analyzer
whenever it is brought into a substan­tially warmer place. If you transfer the
moisture analyzer to a warmer area,
make sure to condition it for about
2 hours at room temperature, leaving it
unplugged from AC power. Afterwards,
if you keep the moisture analyzer con­nected to AC power, the continuous
positive difference in temperature
between the inside of the moisture
analyzer and the outside will practically
rule out the effects of moisture
condensation.

§ Check the voltage rating and the plug design

$ The heating unit of the moisture analyzer has been factory-set to 230 or 115 volts for

technical reasons. The voltage has been set as specified on your order. The voltage setting is
indicated on the manufacturer’s label (see the bottom of the analyzer), for example:
– 230 volts: MA50C-...230..
– 115 volts: MA50C-...115..

! If they do not match: To have the voltage setting changed, contact your local Sartorius

office or dealer, and do not operate your moisture analyzer in the meantime!

Use only
– Original power cords
– Power cords approved by a certified electrician/Sartorius service technician
– If you need to connect an extension cord:

Use only a cable with a protective grounding conductor

§ Connecting the moisture analyzer, rated to Class 1, to AC power (mains supply):

The moisture analyzer must be plugged into a properly installed wall outlet which has a

protective grounding conductor (PE)

Safety Precautions

If you use an electrical outlet that does not have a protective grounding conductor,

make sure to have an equivalent protective conductor installed by a certified electrician as

specified in the applicable regulations for installation in your country.

The protective effect must not be negated by using an extension cord without a protective

grounding conductor.

Information on Radio Frequency Interference

Note: This equipment has been tested and found to comply with the limits for a Class A

digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide

reasonable protection against harmful interference when the equipment is operated in a

commercial environment. This equipment generates, uses, and can radiate radio frequency

energy and, if not installed and used in accordance with the instruction manual, may cause

harmful interference to radio communications. Operation of this equipment in a residential

area is likely to cause harmful interference in which case the user will be required to correct

the interference at his own expense. Changes or modifications not expressly approved

by Sartorius AG could void the user‘s authority to operate the equipment.

The AC adapter rated to Class 2 can be plugged into any wall outlet without requiring

any additional safety precautions. The ground or earth terminal is connected to the

housing, which can be additionally grounded, if required. The data interface is also

electrically connected to the scale housing (ground).

Connecting Electronic Devices (Peripherals)

§ Make absolutely sure to unplug the moisture analyzer from AC power before you connect

or disconnect a peripheral device (printer or PC) to or from the interface port.

Warmup Time

To deliver exact results, the moisture analyzer must warm up for at least 30 minutes after

initial connection to AC power or after a relatively long power outage. Only after this time

will the moisture analyzer have reached the required operating temperature.

Using Verified Moisture Analyzers as Legal Measuring Instruments in the EU*:
$ Make sure to allow the analyzer to warm up for at least 24 hours after initial connection to

AC power or after a relatively long power outage

* including the Signatories of the Agreement on the European Economic Area

Charging the Built-in Rechargeable Battery

Before initial operation, leave the moisture analyzer connected to the line current

(mains supply) for at least 10 hours to charge the built-in rechargeable battery. When the

analyzer is disconnected from line current, the analysis data is retained in memory for

approximately three months.

Weighing Function

Purpose

The MA100/MA50 moisture analyzer
can be used for quick and reliable
determination of the moisture content
of materials of liquid, pasty and solid
substances according to the method of
thermogravimetry.

Notes on Models MA100C-0CE230V1,
MA100H-0CE230V1:

The models MA100C-0CE230V1,
MA100H-0CE230V1 are delivered with
initial calibration ex factory.
Do not exceed the given ambient
temperature range (+15° to +25°C) stated
on the manufacturer’s ID label. The
verifiable weighing program is designated
by the Q symbol in the display.

To ensure reliable measurements, allow
the analyzer to warm up before switching
to the verifiable weighing program.
An internal calibration/adjustment must
be conducted before each measurement
series (see page 54). This applies until
the analyzer has cooled down to ambient
temperature.

25

Operating the Moisture Analyzer

Basics

The moisture of a material is often
mistakenly equated with its water
content. In fact, the moisture of a
material includes of all the volatile
components which are given off when
the sample is heated, resulting in a
decrease in sample weight. Among

such volatile substances are:
– water
– fats
– oils
– alcohols
– organic solvents
– flavorings
– products of decomposition (when a

sample is overheated)

There are many methods to determine

the moisture content of a substance.

Basically, these methods can be divided

into two categories:

When absolute methods are used, the

moisture content is directly determined

(for example, as a weight loss registered

during the drying routine). These

methods include oven drying, infrared

drying, and microwave drying. All

three of these methods are thermogravi-

metric.

When deductive methods are used, the
moisture content is indirectly determined.
A physical property, which is related to
the moisture in the substance, is measured
(e.g., absorption of electromagnetic rays).
These methods include Karl-Fischer
titration, infrared spectroscopy, microwave
spectroscopy, etc.

Thermogravimetry is the process of deter­mining the loss of mass that occurs when a
substance is heated. In this process, the
sample is weighed before and after being
heated, and the difference between the
two weights is calculated.

In a conventional drying oven, circulating
hot air warms the sample from the outside
to the inside. Efficiency is lost during
drying because as the moisture evaporates,
it cools the sample surface.

By contrast, infrared rays (IR rays) pene­trate a sample without being impeded.
Having reached the interior of a sample,
they are converted into heat energy, which
stimulates evaporation, thus drying the
sample. A small part of the IR rays is
reflected from the surface of the substance.

IR-Strahlung

Substanz

Wärmeenergie

IR rays

thermal energy

substance

The quantity of reflected IR rays depends
to a great extent on whether the substance
is light or dark-colored.

Dark Substance Light Substance
Low Reflection High Reflection

How the rays penetrate the sample
depends on the sample’s degree of light­transmitting capacity. If the degree of
light-transmitting capacity is low, the rays
can penetrate only the uppermost layers
of the sample. The heat conductivity of
the sample dictates the degree to which the
heat can be transmitted to the underlying
layers. The higher the conductivity, the
faster and more uniformly the substance
is heated.

The substance should be applied to the
sample pan in a thin, even layer. A height
of approximately 2–5 mm for 5–15 g
substance weight has proved to be ideal.
Otherwise, the sample will not be dried
completely or the analysis time will be
unnecessarily extended, a crust/skin will
form on the surface of the sample or the
sample will scorch, and the analysis results
obtained will not be reproducable, and
therefore, cannot be used.

Incorrect Application of a Sample

When preparing a substance for analysis,
you should use methods that do not
generate heat so that the sample does not
lose moisture before it is analyzed.

Perform initial analysis of a new substance
to test how the IR rays are absorbed by the
sample and converted into heat. The
printout of the intermediate values of the
drying process provides you with this
information at an early stage.

Experience has shown that the temperature
setting selected during the infrared
drying is usually lower than the tempera­ture setting used when working with
a drying oven.

In many cases, the fully automatic shutoff
mode will meet your requirements.
If the final result is higher or lower than
expected, try varying the temperature
setting before resorting to a different
shutoff parameter.

When analyzing samples that lose their
moisture only very slowly or when operat­ing a cold moisture analyzer, the fully
automatic mode may end the drying rou­tine too early, if it does not detect any
analyzable progress in the drying routine
under these conditions. In this case, pre­heat the moisture analyzer for 2–3 minutes
before starting the drying routine or select
a different shutoff parameter.

The Sartorius Moisture Analyzer
Applications Guide will provide you with
important information on the use of
your moisture analyzer.

26

Preparation

Before drying a sample, you must carry
out the following preparations:

– Adjustment to the available measuring

system (if required)

– Sample preparation

– Setting the parameters for drying

program

27

Adjustment to an Existing Measuring System

A moisture analysis method often replaces another drying method (e.g., the oven drying

method), because it is simple to use and requires shorter analysis time. In this case,

you should adapt this method to that of the moisture analyzer in order to obtain values

comparable to those yielded by your standard reference method.

● Perform parallel measurements: take a fresh sample and divide it in half

● Determine the moisture content of the first half using your standard method of analysis

● Analyze the second half of the sample in the moisture analyzer.

Use the following settings:

– fully automatic mode for the shutoff parameter

– lower temperature settings than for the oven drying method

– temperature setting for organic substances: 80 – 100°C

– temperature setting for inorganic substances: 140 – 160°C

$ If the result for the second part does not correspond to that of the first:

– first, repeat the analysis using a different temperature setting

– then use the semi-automatic mode for the shutoff parameter (such as 5 mg/30 s

or the asap mode)

asap stands for “automatic searching/automatic programming”. The asap mode monitors

the drying process and, at the press of a key, calculates a semi-automatic shutoff

parameter for the expected results of the analysis. It then saves the parameter in a

program routine.

$ Vary the shutoff parameter, if required:

– Increase end-point recognition: set the parameter to 2 mg/30 s or 5 mg/60 s

– Decrease end-point recognition: set the parameter to 10 mg/30 s or 5 mg/10 s

Preparing a Sample

Selecting a Sample

● Select a representative part of the whole substance as a sample
– a representative number of individual samples for quality control
– samples which indicate a trend are sufficient for in-process control

$ Homogenize the product before a sample is taken, if required, by:

– mixing or stirring
– taking several samples from different areas of the product
– taking several samples at defined intervals

● Take only one sample at a time for a given analysis and prepare it as quickly as possible.
In this way, it will not lose or gain moisture as a result of the ambient conditions.

$ If you need to analyze several samples at a time, the samples must be sealed in air-tight

containers, in order to be sure that the storage conditions do not alter the state or
condition of the samples:
– Warm or highly volatile substances lose their moisture very quickly.
– If you store the samples in a container, the moisture can condense on the walls

of the container.

– If the container is too big and not filled completely, the sample can exchange its

moisture with the air remaining in the container.

$ Mix condensed moisture back in with a sample, if necessary.

Preparing a sample

● When crushing a sample, avoid any contact with heat:
heat results in moisture loss.

● Crush a sample with
– a pestle
– a shredder (see below)

For liquids containing solids, use
– a glass stirrer
– a spoon or
– a magnetic stirrer.

$ Use an appropriately designed tool for shredding a sample.

Using disposable sample pans

● Use only Sartorius disposable sample pans (inner diameter = 92 mm). Reusing sample
pans leads to poor reproducibility of results:

– after cleaning, sample residues can still remain on the pan

– residues from cleaning agents can evaporate during the next moisture analysis

– scratches and grooves inflicted during cleaning provide surfaces on which

the rising hot air produced during the drying process can act, resulting in a more
pronounced buoyancy

28

29

Applying a Sample to the Sample Pan

● Apply the sample to the sample pan in a thin, even layer (height: 2 to 5 mm, weight:
5 to 15 g); otherwise:
– a sample applied unevenly will result in a nonuniform distribution of heat
– a sample will not be dried completely
– the analysis time will be unnecessarily extended
– the sample burns or a crust/ skin forms on its surface as a result of a very thick layer
– the crust makes it difficult or impossible for moisture to escape from the sample

during the drying process

– uncertain and unknown quantity of moisture remains in the sample

● Apply liquid samples, pasty samples or samples that can melt to a glass fiber filter
(order no. 6906940); you will obtain the following advantages:
– uniform distribution due to the capillary effect
– prevents liquids from beading together and forming drops
– with larger surfaces, the moisture can evaporate faster
– considerably more convenient than the “sea-sand method”

When drying samples containing sugar, a crust or skin can form and seal the surface.
A glass fiber filter is especially helpful in such cases. The moisture can evaporate
downwards through the surface of the filter. You can avoid or limit the crust/skin
formation if you place the glass fiber filter on top of the sample.

● Cover solid, heat-sensitive samples with a glass fiber filter (order no. 6906940);
you will obtain the following advantages:
– gentle heating, because the sample surface is shielded from excessive heat
– higher temperature setting can be selected
– uniformity of the sample surface
– fast evaporation of the moisture
– excellent reproducibility for samples containing fat

Avoiding the Formation of Crust/Skin

You can add “solvents” to the sample to prevent the formation of crust/skin during the
analysis runs. The weight of a solvent you apply to the sample will not influence the final
result of an analysis.

● Once you have closed the sample chamber, open it again within 2 seconds after you
hear a beep tone.

● Apply a solvent to the sample

● Close the sample chamber and start the analysis run as usual

Heating Programs

To perform a moisture analysis of a
substance, you can choose among four
heating programs:

– Standard drying

– Quick drying

– Gentle drying (MA100 only)

– Phase drying (MA100 only)

– High-temperature drying

Standard drying:
For the standard program, you need to
enter the final temperature.

Quick drying:
For quick drying, you need to enter
the final temperature. The heat output
is higher.

Gentle drying (MA100 only):
For gentle drying, you need to enter
the final temperature and time required
to achieve the final temperature.

Phase drying (MA100 only):
Phase drying comprises three drying
phases. You need to enter the temper­ature for each phase, including the time
for the first and second drying phases.
The shutoff parameters will be activated
only in the 3rd phase.

High-temperature drying:

– For temperatures < 200°C as for

standard drying

– For temperatures > 200°C: heating up

to selected temperature as for gentle
drying

● From the 10

th

to the 30thminute:
Nominal temperature in 5 levels up
to 200°C

Standby Temperature

– Temperature set to defined value when

the sample chamber is closed

Weighing-in

You can enter the weight limits for the
initial weight of your sample (minimum
and maximum or target weight with

Example 5: Timer Shutoff Combined with Fully Automatic Shutoff Mode (MA100 only)

The moisture content of 1.5 g of dispersion adhesive is to be analyzed. While heating, the product forms a skin that makes it difficult for
moisture to evaporate from the sample. Increased moisture loss causes this skin to crack, enabling the moisture to evaporate easily again from
the sample. To prevent the moisture analyzer from shutting off too early during the initial phase, a minimum time for the drying procedure
is entered. The analysis is to be ended automatically as soon as a constant weight is reached.

Weighing System Settings

Calibration, Adjustment

Purpose
Calibration is the determination of the
difference between the weight readout
and the true weight (mass) of a sample.
Calibration does not entail making any
changes within the weighing system.

Adjustment is the correction of the
difference between the measured value
displayed and the true weight (mass)
of a sample, or the reduction of the
difference to an allowable level within
maximum permissible error limits.

Features
Calibration can be performed externally
or, with the MA100, internally.

External calibration can be performed:
– with a factory-defined weight
– with a user-defined weight

You can have calibration and adjust-

ment results documented as a ISO/GLP-

compliant printout; see the next page.

External Calibration/Adjustment
with a User-defined Weight

You can define a weight for calibration/
adjustment. External calibration/
adjustment must be performed with
weights that are traceable to a national
standard and that have error limits which
are at least 1/3 of the required tolerance
of the display accuracy. The defined
weight must equal at least 10% of the
maximum weighing capacity.

See page 52 for the external
calibration/adjustment sequence.
For this example, select “Ext. cal./adj.;
user-defined weight.”

The moisture analyzer has a
factory-set calibration weight value
(see “Specifications”).
Enter the factory-defined value
manually:

● Select Setup menu: Press the s key

● Select menu item

! Warning When Using Pre-wired

RS-232 Connecting Cables!

RS-232 cables purchased from other
manufacturers often have incorrect pin
assignments for use with Sartorius
weighing systems! Be sure to check the
pin assignments against the chart
below before connecting the cable and
disconnect any lines marked “Internally
Connected” (e.g., pin 6). Failure to
do so may damage or even completely

Data Input Format
You can connect a computer to your weighing system to send commands via the weighing
system interface port to control functions and applications of the weighing system and
the drying unit. SBI functions for remote control are only useful, if the current device/appli­cation mode can be read out any time.

The commands sent are control commands and may have different formats; e.g., control
commands can have up to 26 characters. Each character must be transmitted according to
the settings configured in the Setup menu for data transmission.

Format for Control Commands
Format 1: Esc ! CR LF
Format 2: Esc ! _ CR LF
Format 3: Esc ! # _ CR LF
Format 4: Esc ! # max. 20 &_ CR LF

Esc: Escape _: Underline (ASCII 95)

Synchronization

During data communication between the
moisture analyzer and an on-line device
(computer), messages consisting of ASCII
characters are transmitted via the interface.
For error-free data communication, the
parameters for baud rate, parity, handshake
mode and character format must be the
same for both units.

You can adapt your moisture analyzer
by setting corresponding parameters in the
Setup menu.

If you do not plug a peripheral device
into the analyzer’s interface port, this will
not generate an error message.

Handshake

(Sartorius Balance Interface) has
transmit and receive buffers. You can
define the handshake parameter in
the Setup menu:

– Hardware handshake (CTS/DTR)

– Software handshake (XON, XOFF)

Hardware Handshake

With a hardware handshake, 1 more
character can be transmitted after CTS
(Clear to Send).

Software Handshake

The software handshake is controlled
via XON and XOFF. When a device is
switched on, XON must be transmitted
to enable any connected device to
communicate.

When the software handshake is
configured in the Setup menu, the
hardware handshake becomes active
after the software handshake.

The data transmission sequence
is as follows:

Moisture ––– byte –––> Computer
analyzer ––– byte –––> (receiving
(transmitting ––– byte –––> device)
device) ––– byte –––>

<––– XOFF –––

––– byte –––>
––– byte –––>

…

(Pause)

…
<––– XON –––
––– byte –––>
––– byte –––>
––– byte –––>
––– byte –––>

Transmitting Device:

Once XOFF has been received, it prevents
further transmission of characters.
When XON in received, it re-enables the
transmitting device to send data.

Receiving Device:

To prevent too many control commands
from being received at one time, XON
is not transmitted until the buffer is
almost empty.

Activating Data Output

You can define the data output parameter
so that output is activated either when a
print command is received or automatically
and synchronously with the analyzer
display or at defined intervals (Program:
Printout intermediate results: On:
Print interval).

Data Output by Print Command

The print command can be transmitted by
pressing p or by a software command
(Esc P).

Digital Input/Output Ports

Monitoring, Remote Control

You can monitor and remote-control
the moisture analyzer. For this purpose,
you should know the operating state
of the unit.

The following external devices can be
used here:

– Status display with digital input ports

– Process logic controllers

– Computer with communications port

Via the communications port, the status
of the moisture analyzer and therefore
the operating state of analysis can
be read out. The moisture analyzer is
remote-controlled by the functions
used to activate the key functions.

65

Functions for Remote Control
(see also “Data Input Format” and
“Data Output Format”):

Read out the moisture analyzer status:
ESCars_

Block/unblock the keys on the moisture
analyzer:
ESCO / ESCR or on the moisture analyzer
via Setup: Device

Activate key functions:
ESCP, ESCkF1_ to ESCkF11_

The respective operating state of the mois­ture analyzer will be transmitted to the
digital output ports according to the chart
“Operating State of Analysis” (see below).

The moisture limits for the control
function at the ANALYSIS END (in toler­ance, < min., > max.) are to be entered
under soft key

Mode: Limits for

control function.

Remote control via the universal remote
control switch input (pin 15):

● Set the universal remote control switch
function to “Function key F1” (“Setup:

– Resistance of the protective grounding

conductor < 0.2 ohm measured with a
commercially available multimeter

– Insulation resistance > 2 megohms

measured with a constant voltage of at
least 500 volts at a 500 kohm load

The duration and number of measure­ments should be determined by a quali­fied Sartorius service technician accord­ing to the particular ambient and
operating conditions. However, such
inspection must be performed at least
once a year.
