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.

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
