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 sample 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, and lead to a reduction in its weight. Among such volatile substances are:

– Water – Fats – Oils – Alcohols – Organic solvents – Flavorings – Volatile components, products of decomposition (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 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.

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 processes.

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 heat the sample directly.

IR-Strahlung

Substanz

Wärmeenergie

Operating Instructions Moisture Analyzer MA37

Basic Principles

The IR rays that do not heat the sample are either reflected from surface of the sample or absorbed unimpeded into the sample.

The color and surface characteristics of the sample determine how effective the heating process is. For example, dark substances absorb IR rays more effectively than light substances.

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 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).

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.

Due to the fact that the supply of IR rays results in intensive energy input into 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 switch-off 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.

The Application Guide for the Sartorius Moisture Analyzer provides you with important information on the use of your moisture analyzer.

Operating Instructions Moisture Analyzer MA37

Basic Principles

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

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.

Perform parallel measurements:

t Take a fresh sample and divide it in half t Determine the moisture content of the first half using your standard method

of analysis

t Determine the moisture content of the second half using the following settings:

– Fully automatic mode for the switch-off criterion – 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 of the second analysis does not correspond to that of the first:

1. First, repeat the analysis using a different temperature setting

2. Then use the semi-automatic mode for the switch-off criterion (for example with a different loss rate per 24 s)

Change the switch-off criterion if required: – Increase end-point recognition: Set the parameter to 2 mg/24 s or 1 mg/24 s – Decrease end-point recognition: Set the parameter to 10 mg/24 s or 20 mg/24 s

Preparing the Sample

Select a sample:

t 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

t 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

t 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.

t 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.

Operating Instructions Moisture Analyzer MA37

Basic Principles

t Mix the condensed moisture back in with a sample if necessary.

Prepare the sample:

t When crushing a sample, avoid any contact with heat.

Heat results in moisture loss.

t Crush the sample using:

– Pestle – Lab mill

If the sample is liquid containing solids, use one of the following tools:

– Glass stirrer – Spoon – Magnetic stirrer

t Use an appropriate tool for grinding the sample.

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).

Operating Instructions Moisture Analyzer MA37

Basic Principles

Apply the sample to the sample pan:

t Apply the sample to the sample pan in a thin, even layer (height: 2 to 5 mm,

weight: 5 to15 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 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

t

Apply liquid samples, pasty samples, transparent 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.

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

Heating Programs

Two heating programs are available for performing moisture analysis of a substance:

– Standard drying – Gentle drying

Standard drying: For standard drying, you need to enter the final temperature. The final temperature is reached using an overshoot if necessary. The maximum set temperature is 160°C.

Moisture Analysis

Operating Instructions Moisture Analyzer MA37

Moisture Analysis

Purpose: The moisture analyzer can be used to determine the moisture content of liquid,

pasty, or solid samples.

Accessories: Depending on the consistency of the sample, one or two filters are recommended in

order to distribute the sample optimally in the sample pan. – Liquid sample: Tare one filter with the sample pan, then distribute the sample

drop by drop onto the filter.

– Pasty sample: Tare two filters with the sample pan, then place the sample

between the two filters and press together evenly.

– Solid sample: Distribute the granulated sample evenly onto the sample pan

without a filter. Use one or two filters for solid samples that liquefy at high temperatures or contain fat or sugar, in order to prevent crusting.

Danger of poisoning or caustic burns!

Substances that contain poisonous or caustic ingredients may produce poisonous gases when dried, which can cause irritation (to the eyes, skin, or airways) or nausea and lead to serious injury or death. – These samples must only be dried in a laboratory hood.

Corrosion due to aggressive vapors!

Substances that emit aggressive vapors when heated may cause condensation to form on cooler housing parts and lead to corrosion. – Use small sample quantities of these substances.

Calibration and Adjustment

Operating Instructions Moisture Analyzer MA37

Calibration and Adjustment

Background During calibration, a calibration weight is used to determine how much the

displayed value deviates from the actual measurement value. This deviation is compared against a preset target value. The subsequent adjustment corrects this deviation or reduces the permissible error limits. Calibration and adjustment are combined in one process in the moisture analyzer. After each calibration the analyzer is automatically adjusted.

When and How Often The moisture analyzer must be calibrated and adjusted, for example:

– When the ambient conditions have changed (temperature, humidity, or air

pressure)

– When the moisture analyzer is set up in a different location or moved in its

current location.

An external calibration weight is required for calibration and adjustment (100 g).

Please note the tolerance of the calibration weight being used.

You can activate the printout in the Printout menu (see section “Printout” in Chapter “System Settings”) and select whether values only or values and intermediate values are printed.

Example: Intermediate value output 02:00 8.16 %M

USB Interface

Operating Instructions Moisture Analyzer MA37

Output Format

The characters are printed with the header. No more than 22 characters can be displayed in one line. Longer character sets are printed out on two lines. The printout is set to justified alignment. The following characters and abbreviations are used:

Space _ A space is indicated with an underscore: _

Carriage Return CR A carriage return (or line break) is abbreviated with “CR.”

Line Feed LF A line feed is abbreviated with “LF.”

Example 1 The first example has a 6-character header (columns 1 to 6) and can therefore be printed in one line. Column 7 is used for signs before values (+, -). Values are given in columns 8 to 16 with decimal points or text. The unit characters are given in columns 17 to 20.

If the unit “%M/S” is selected, use four characters to print out the units because no space is printed before a unit. In a print interval, however, one line is generated with the following: – Five characters for a header – One character for a space – Nine characters for the values including signs – One space – Four characters for the units

Problems

Problem/Meaning Remedy

Selected temperature is too high and the sample is oxidized; sample is boiling or burning and the splashes are continuously changing the weight.

– Reduce drying temperature – Lay glass-fiber filter onto the sample – Reduce the sample quantity or apply

the sample more evenly

– Select a semi-automatic switch-off

criterion or select timer mode

Measurement time too long – Increase temperature

– Reduce sample quantity – Preheat the analyzer by running a

drying process for 2 or 3 minutes with an empty sample pan, for example

Sample loses weight before it is analyzed – Remove the sample pan and apply

the sample outside the analyzer Sample is liquid or pasty – Use glass fiber filter Sample has only a low moisture content – Increase sample quantity Insufficient heating output – Clean temperature sensor Place of installation unstable

(vibrations, etc.)

– Set up the scale in another area

Care and Maintenance

Service

To ensure its continued weighing accuracy, we recommend performing regular servicing on your analyzer at least once a year. The Sartorius Service Center offers different service contracts for this purpose, which can be individually adapted to suit your needs (see also www.sartorius.com/service). Each service produces a calibration certificate. The analyzer and its connections must undergo a technical safety inspection on a regular basis carried out by an electrician (e.g., every 2 years).

Repairs

Repair work must only be carried out by trained service technicians. The analyzer must be unplugged during repair work. Unplug the power cable from the socket. Failure to do so may affect the measurement accuracy of your analyzer and pose aserious risk to the user. Contact the Sartorius Service Center or a Sartorius dealer to arrange for proper repairs.
