12 Working Modes ­ General Information
Standard version of MA_X balance feature the following working modes: Weighing Means of operation: weight of a load is determined through an indirect measurement. A balance measures gravitational force which attracts the load. An obtained result is processed to a digital format and displayed in a form of measurement result. Drying Means of operation: determining moisture content in a sample, obtained by vaporization of all moisture components from a sample placed inside a drying chamber of a moisture analyzer. A measurement result is automatically calculated by the software and visualized on an ongoing basis on moisture analyzer’s display by comparing mass of a sample on measurement start, in progress, and at the end of drying process.

14 Sample Preparation for Drying
This section of the MA_X user manual contains data on setting optimum test results during drying processes. There are hints for selection of appropriate drying parameters for various materials and substances.
14.1 Means of Moisture Content Measurement on a Moisture Analyzer Measurement of moisture content in a tested sample is carried out by determining loss of mass in a sample by its heating (humidity evaporation). PCE moisture analyzer MA_X comprises two components: a precision balance and a drying chamber. Compared to standard moisture content determining methods, the measurements with application of PCE moisture analyzer is much quicker and does not require additional mathematical calculations (a result of moisture content is previewed on an ongoing basis during product testing process). Independently on moisture content determining method, the measurement accuracy is highly influenced by means of sample preparation and selection of testing parameters, such as:
– Sample size – Sample type – Drying temperature – Drying time
In practice, the measurement accuracy is not as important as the speed of obtaining measurement result (control over technological process). Thus, heating a sample (with application of a halogen filament) carried out by a moisture analyzer, makes the measurement process very time efficient and short. Measurement speed can be additionally increased by appropriate adjusting moisture analyzer’s parameters depending on tested substances.
© PCE Instruments 61

Optimum temperature and drying time depend on sample type and size, and anticipated measuring accuracy. Selection of drying parameters can only be carried out on basis of test measurements.
14.2 Sampling and Preparation Sample features, its preparation and size are very important factors influencing the speed and accuracy of measurement process. Means of sampling and preparation are extremely important for repeatability of measurement results, as a sample should be a representative part of tested substance.
Final measurement result is vastly conditioned by precise and considered sample preparation. A sample used for analysis has to represent the total structure of tested material. Sampling process should determine: sampling means, sample disintegrating, particle size after disintegration, sample uniformity and other. The sampling process should be carried out as quickly as possible, so that a sample does not lose or absorb humidity from surrounding area. Applied sampling standards should match individual user needs and requirements of tested material, its consistence and sample size.
Number of samples Increasing number of tested samples also increases statistic measurement certainty. Number of samples depends on uniformity of tested material, its purity, accuracy of applied measuring method and anticipated accuracy of obtained results.
Material mechanical disintegrating for measurements Applied disintegrating method should be selected appropriately to tested material. Substances that are hard and brittle (crisp) can be disintegrated by cutting. Grinding such substances may cause their heating and thus humidity vaporization, resulting in unreliable measurement results. Unless a substance can be prepared for measurement otherwise than grinding, any possible moisture content loss should be calculated.
Use of high-silica sand Ensuring optimum substance drying requires that a sample has the largest possible surface for moisture content evaporation. Test results of moisture content for substance with surface in a form of a shell (e.g. glucose syrup) or doughy (e.g. butter), can be much more reliable if a sample is mixed with a dried high-silica sand (improvement of measurement accuracy and repeatability). While using mixture, disposable weighing pan with extended brim must be applied (greater volume of a sample).
Grease in a form of paste or melting substances Such substance requires testing with use of a filter made of glass fibre, which considerably increases active evaporation surface by separating the substance between the fibre. Initial filter drying is necessary only in case of measurements which require very high accuracy.
© PCE Instruments 62

Liquid substances It refers to liquid substances, which by creation of drops on their surface, caused by surface tension, may render difficulties in drying process. In such cases, it is proved to use a glass fibre filter to shorten measurement time. The filter causes separating tested liquid around the fibres, and increasing active evaporating surface. Initial filter drying is necessary only in case of measurements which require very high accuracy.
Substances with structure of leather or temperature sensitive In case of such substances it is proved to use a glass fibre filter. While testing, a substance is placed on a drying pan, and sample surface is covered with a filter, which protects the sample from direct heat radiation. In such case, the sample is heated by convection (which is milder than radiation).
Substances containing sugar The surface of such substances often may caramelize during testing procedure. Therefore, it is recommended to use thin layer of a sample, and moderate drying temperature.
Sample distribution on a pan:
Loose materials Dried in their natural state, i.e. in their natural form or disintegrated. Sample disintegration causes smaller dispersion between the following measurements. Sample mass should not be too high, and the sample should be evenly spread on whole surface of the drying pan.
Liquid substances Semi-fluid substances are dried in their natural form. Large amount of grease (fat) occurring in some of substances makes moisture content determination difficult. In such case it is recommended to use additional components, which increase sample’s active surface and aid moisture content releasing process from a sample. Such components are high silica sand, blotting paper or filter. Before drying a tested substance, initially dry the additional component, so that its humidity is close to zero.
Solid objects Depending on solid object’s structure (dense or loose), moisture content determining process may take short or long time. The size of solid’s surface determines the speed of drying process, and measurement reliability. Thus, the surface of a solid object should be as large as possible. Since solid objects release moisture through their outer surface, sample thickness is another important factor.

15 Selection of Drying Parameters
15.1 Selecting Optimum Mass for a Sample Sample mass influences the accuracy of measurement result and measurement time. Higher mass of a sample, causes higher amount of water (moisture content) which needs to evaporate, and therefore measurement time is also longer. Obtaining short measurement time is feasible in case of small sample mass, but sample mass cannot be too small, as it may negatively influence required measurement accuracy.

15.2 Influence of Sample Weight on Measurement Result Repeatability
Sample mass considerably influences repeatability of measurement results obtained on a moisture analyzer. Relation between sample mass and repeatability is presented in a table below.

Sample weight ~2g ~10 g

Repeatability ±0.05% ±0.01%

The above data refers to a model, uniform sample, containing no moisture due to the evaporation process and showing no signs of decomposition (e.g. wet high-silica sand).

The results uncertainty cannot be avoided, this is due to sample nature and moisture analyzer repeatability. In practice, it means that obtained measurement result may exceed repeatability values provided above.
© PCE Instruments 64

15.3 Drying Temperature Drying temperature has the largest impact on drying time. Temperature value depends on type of dried substance. Too low drying temperature causes too low moisture content evaporation (underdried sample), and consequently unnecessary extending of measurement time. Too high drying temperature causes burning of dried sample (sample overheating, chemical decomposition). Drying temperature of traditional method (using a furnace) is specified in applicable industry or company standards. Unless standards apply, then temperature should be adjusted by tests.
On selecting drying temperature value, proceed as follows: – Determine moisture content in a sample – Determine temperature of substance chemical decomposition by tests – Compare result obtained on a moisture analyzer with the one of traditional method
When drying a sample with high moisture content, it is possible to shorten measurement time by selecting quick or step drying mode. In such case, the majority of moisture content is released drying temperature higher than set. Only after some time, the temperature is lowered to the set value, and maintained until completing drying process.
15.4 Selecting Drying Profile The software of moisture analyzer enables selecting one of four drying profiles:
– Standard – Quick – Mild – Step
STANDARD profile Standard profile is the most frequently used of all drying profiles. It enables accurate determining of moisture content in a dried sample.
MILD profile Mild profile is used in case of drying substances that are sensitive to rapid heat emitted by filaments operating at full power in the initial stage of drying process. This profile prevents from decomposing of substances sensitive to heat by mild temperature increase in set amount of time (time interval has to be selected by tests). Mild profile is recommended to drying samples of leather structure.
© PCE Instruments 65

FAST profile Fast profile is recommended to drying samples that moisture content varies from 5%, and 15%. In the initial stage of Fast profile, heating takes place at full power of the filaments, causing heating the drying chamber to increased temperature (maximum temperature value is higher by 30% from set drying temperature). Overheating compensates heat loss during evaporation of large moisture content in the test’s initial stage.
STEP profile Enables determining up to three steps with random drying temperature. Step profile is recommended for drying substances with moisture content over 15%. Temperature and heating time in each step have to be adjusted by tests.
15.5 Drying Time Drying time is set by selecting one of available finish mode criteria. This means that a moisture analyzer must meet pre-set criterion (one of the requirements: mass over time, time) to automatically finish the drying process. Finish of drying process can be triggered by amount of time, independently on loss in mass. This criterion is used for substances that may decompose during drying process, and their mass does not reach constant value. The second criterion is loss in mass (less than 1 mg) in defined amount of time.
Automatic finish mode (Auto switch off mode) The operator can choose between various types of finish modes:
– Automatic 1 (change 1mg/10s) – Automatic 2 (change 1mg/25s) – Automatic 3 (change 1mg/60s) – Automatic 4 (change 1mg/90s) – Automatic 5 (change 1mg/120s)
Time-defined finish mode – drying process finish takes place on elapsing a set amount of time, independently on measurement result (maximum drying time 99 hours 59 minutes).
Manual finish mode – the operator ends drying process manually by pressing START/STOP soft key on moisture analyzer’s display.
© PCE Instruments 66

Defined finish mode – user defined criterion. The operator determines the limit value for loss of mass and time in which the loss of mass must not exceed a pre-set value. As the moisture analyzer reaches the set criterion it automatically finishes the measurement (drying process). – User defined 1 (m ­ change of mass and t ­ change of time must be given, the former in mg, the later amounts to 120 s. maximally) – User defined 2 (set moisture content change ratio %M over time 60s)
15.6 Drying Profile Analysis For the first case, the drying profile is an asymptote. Moisture content value remains constant even after long drying time. Using this drying profile makes determination of humidity easy. The measurement result is always referred to constant value of asymptote. The result corresponds easily and it is not difficult to select a proper criterion of finish mode. For the second case the drying process is quick at the beginning, next it stabilizes. Moisture content value is never constant. Drying process profile may proceed as follows: The sample undergoes thermal decomposition, wherein evaporation takes place and as a result the product weigh decreases. Evaporation of grease, oil, plastic or other volatile materials may take much more time than in case of water. Difficult to evaporate materials drop weight. Result obtained using this mode may be optimistic:
– Lower temperature may slower material reaction. – Selection of appropriate criterion may let the user recognize end of analysis, within
described drying step. – Constant drying often assures good drying results. – Maintaining start sample weight permanently (+10%….+20%).
16 Drying
DRYING mode has been designed to enable determination of moisture content of a given sample. The moisture content value is obtained via evaporation of moisture from sample placed inside of the drying chamber. The result is calculated automatically (and displayed) in real time, the calculation is made on the basis of sample mass at the beginning, in the course, and at the end of the process.
