To prevent damage to the equipment,
read these operating instructions thoroughly before using your MA35 moisture analyzer. 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 on 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; operate it only under the ambient conditions specified in these instructions.
! If you use electrical equipment in
installations and under ambient conditions subject to stricter safety standards than those described in the manual, you must comply with the provisions as specified in the applica­ble regulations for installation in your country.
The moisture analyzer may be operat-
ed 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 “Connect­ing the Moisture Analyzer to AC Power” in the chapter entitled “Getting Started”).
The analyzer 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 cord 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. Note on installation: The operator shall be responsible
for any modifications to Sartorius
equipment or connections of cables
not supplied by Sartorius and must
check and, if necessary, correct these
modifications. On request, Sartorius
will provide information on the
minimum operating specifications. – Protect the analyzer from contact with
liquid – If there is visible damage to the
equipment or power cord, unplug the
equipment and lock it in a secure place
to ensure that it cannot be used for
the time being.
4
! Clean your moisture analyzer only
according to the cleaning instructions (see “Care and Maintenance”).
Do not open the analyzer housing.
Hazards for persons or equipment
posed by certain sample materials:
$ Please contact your local Sartorius
Service should any problems arise with your device.
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
– leave 1 m (3 ft.) above the moisture
analyzer
Do not place any flammable substances
on, under or near the moisture analyz­er, because the area around the heating unit will heat up
Be careful when removing a sample
from the chamber: the sample, the heating unit and the sample pan may still be extremely hot
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 into 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 functioning (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.
Prevent excess heat build-up around
the analyzer
5
Poisoning Caustic burns
– Substances containing toxic or caustic or
corrosive components may only be dried under a fume hood. The value for the “lower toxic limit” in a work area must not be exceeded.
Corrosion: – Corrosion may be caused by substances
that release aggressive vapors during the heating process (such as acids).
We recommend working with only small
quantities of such samples, to avoid build-up of vapors that can condense on cold housing parts and can cause corrosion.
The user shall be liable and responsible
for any damage that arises in connection with this moisture analyzer.

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, condition it for about 2 hours at room temperature, leaving it unplugged from AC power. Leave the device connect­ed to the power supply after first connecting.

Setting up the Moisture Analyzer

§ Position the components listed below in the order
given:
– Pan draft shield
– Pan support
– Disposable sample pan

Connecting the Moisture Analyzer to AC Power

§ Check the voltage rating and the plug design $ The heating element has been factory-set to 230 V
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: MA35M-…230… – 115 volts: MA35M-…115…
! CAUTION! If the voltage indicated on the label does
not match your local line voltage: Do not operate your moisture analyzer; contact your local Sartorius office or dealer.
Use only – Genuine Sartorius power cords, or – Power cords approved by a certified electrician – 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):
Plug the power cord into an electrical outlet (mains
supply) that is properly installed with a protective
grounding conductor (protective earth = 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.
Make sure the protective grounding effect is not
neutralized by use of an extension cord that lacks a
protective grounding conductor.

Basic Principles

Purpose

The moisture analyzer can be used for
quick and reliable determination of the moisture content of materials of liquid, pasty, and solid substances using the thermogravimetric method.

Material

The moisture of a material is often
mistakenly equated to its water content. In fact, the moisture of a material includes all of the volatile components which are emitted when the sample is heated, irrespective of the type of material. Among such volatile
substances are: – Water – Fats – Oils – Alcohols – Organic solvents – Flavorings – Volatile components, products of decom-
position (when a sample is overheated)
There are many methods for determining
the moisture content of a substance.
Basically, these methods can be divided
into two categories:
When deductive methods are used, the
moisture content is indirectly deter­mined. A physical property related to the moisture in the substance is measured (e.g., conductivity). These methods include capacitive and spectroscopic approaches.
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, circulat-
ing 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) pene-
trate the substance. The majority of the rays reach the interior of a sample, and then directly heat the sample.
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 thermogravimetric.
14
IR-Strahlung
IR rays
Wärmeenergie
Heat
Substanz
Substance
Dark substance Low reflection
Bright substance Strong reflection
How the rays penetrate the sample depends on the permeability of the sample. 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 proportion of the IR rays which does not heat the sample is either reflected on the surface of the sample or penetrates the sample unimpeded.
The color and surface properties of the sample significantly influence how effective the heating process is. For example, dark substances absorb IR rays better than bright substances.
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 reproducible (and hence cannot be used).
15
While preparing substances for measure­ment, no processes may be used that generate heat. The heat generated may result in a loss of moisture prior to the measurement.
Perform initial analysis of a new substance to test how the IR rays are absorbed by the sample and converted into heat. A printout of the intermediate values of the drying process provides information on this at an early stage.
Since introducing IR rays produces intensive energy input in the sample, the temperature setting selected for infrared drying is usually lower than the temperature setting used when working with a drying oven.
In many cases, the fully automatic switch­off 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 switch-off criterion.
When analyzing the 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 since no analyzable progress in the drying routine can be detected. In this case, preheat the moisture analyzer for two to three minutes before starting the drying routine, or select a different switch-off criterion.
16

Preparation

Before drying a sample, you must carry
out the following preparations:
– Adjust against the existing measurement
system – Prepare the sample – Set the drying program parameters
If required, homogenize the product
before a sample is taken by: – Mixing or stirring – Taking several samples from different
areas of the product – Taking several samples at defined
intervals
Adjusting against an
Existing Measurement System
A moisture analysis method often
replaces another drying method (such as 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.
Setting the Drying Program
Parameters
– By selecting the right drying program
parameters, it is possible to achieve the same results as the standard procedure in a much shorter time and with much simpler operation.

Preparing the Sample

t Select a sample
Select a representative part of the whole
substance as a sample.
– Choose a representative number of
individual samples for quality control
– Choose enough samples to indicate a
trend for in-process control
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 several samples need to be taken
simultaneously, the samples must be
sealed in airtight containers to ensure
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 the condensed moisture back in with
a sample if necessary.
Prepare the sample
When crushing a sample, avoid any
contact with heat. Heat results in
moisture loss.
t Crush the sample using
– Pestle – Lab mill
17
t Use an appropriate tool for grinding
the sample.
t If the sample is liquid containing solids,
use one of the following tools: – Glass stirrer – Spoon – Magnetic stirrer

Use a disposable sample pan

t Use only Sartorius disposable sample
pans (inner diameter of 90 mm). Reusing
sample pans leads to poor repeatability
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 made during
cleaning result in damage that forms
points of attack for hot, rising air
produced during the drying process
(more pronounced buoyancy).
t Apply liquid samples, pasty samples, or
samples that can melt to a glass-fiber filter (order no. 6906940); this provides the following benefits:
– Uniform distribution due to the capillary
effect
– Liquids are prevented from beading
together and forming drops
– With larger surfaces, the moisture can
evaporate faster
– Colorless/transparent samples do not
reflect
– 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 particularly useful in such cases. The moisture can evaporate downwards through the surface of the filter. Crust/skin formation can be prevented or limited by placing the glass-fiber filter on top of the sample.
Distribute the sample on the
sample pan

t Distribute the sample on 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 – The sample will not be dried completely – The analysis time will be unnecessarily
extended – The sample will burn or a crust/skin will
form 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 – An uncertain and unknown quantity of
moisture will remain in the sample
18
t Cover solid, heat-sensitive samples with
a glass-fiber filter (order no. 6906940); this provides the following benefits:
– 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 repeatability for samples
containing fat

Adjusting the Analyzer

Heating Element Adjustment

The procedure for adjusting the heating element is described in the instructions supplied with the YTM15MA temperature adjustment set.

Weighing System Adjustment

To adjust the weighing system, perform
calibration and adjustment as described in the following.
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 a level within specified permissible error limits.
Features
Calibration is performed externally with
the following weight value:
– MA35: 30 g; see “Accessories,” order no.
YSS43-02
You can have calibration and adjust-
ment results documented as a ISO/GLP­compliant printout (see the page after next for an example).

Interface Port

Purpose
The moisture analyzer has an interface
port for connecting an external printer or computer (or other peripheral device).
External Printer You can use an external printer to
generate printouts.
Computer Analyses and calculated values can be
transmitted to a computer for further evaluation and for documentation.
! Warning When Using Pre-wired
RS-232 Connecting Cables:
RS-232 cables purchased from other
manufacturers often have pin assign­ments that are incompatible with Sartorius products. Be sure to check the pin assignments against the chart on the next page before connecting the cable, and disconnect any lines identi­fied differently from those specified by Sartorius (e.g., pin 11). Failure to do so may damage or even completely ruin your moisture analyzer and/or peripheral device(s).
Preparation
For instructions on adapting the inter-
face port to the peripheral device, please
refer to the chapter entitled “Configura-
tion.”
To get the most from the versatile
characteristics of your moisture analyzer
with regard to documentation of results,
we recommend connecting a printer
from Sartorius. The resulting printouts
will contribute decisively to simplifying
GLP-compliant practices.
