Basic Principles 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.
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.
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.
Basic Principles tt Mix the condensed moisture back in with a sample if necessary. Prepare the sample: tt When crushing a sample, avoid any contact with heat. Heat results in moisture loss. tt 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 tt Use an appropriate tool for grinding the sample.
Basic Principles Apply the sample to the sample pan: tt 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
Basic Principles Gentle drying: For gentle drying, you need to enter the final temperature. The maximum set temperature is 160°C. The target temperature is reached more slowly and the measurement time is extended. Gentle drying is recommended for sensitive samples. T [°C] Standardtrocknung t [s] Standby Temperature Temperature set to defined value when the sample chamber is closed. Heating only occurs when the analyzer is in a measurement cycle.
Basic Principles Starting the Analysis –– After closing the hood: If the initial weight condition is met, the analyzer prompts you to close the hood. The start weight is accepted as soon as the sample chamber is closed and the measurement value is stable. End of Analysis –– Fully automatic: The analysis ends as soon as the weight loss per 24 s is below an automatically detected threshold. Weight Moisture (steam) Autom.

Care and Maintenance 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.
Care and Maintenance Contaminated Equipment: – Health risk from product contamination due to product deposits and the collection of residue with microbial contamination. – Health risk from biological or microbiological substances. – Observe cleaning specifications. – Check the cleaning result closely. Cleaning the Heating Module Danger of Burns: The inner part of the heating module and parts of the sample chamber may be extremely hot. Wait until the heating module has cooled completely.
Care and Maintenance 4) Clean the heating element and temperature sensor with a weak solvent such as ethanol. 5) If necessary, pull the air extractor grate out of the heating module. Then clean the heating module and grate in a dishwasher. 6) Once cleaning is complete, reassemble the heating module and reinstall in the analyzer, following the instructions in reverse order. The heating module must snap into place on the analyzer.
Care and Maintenance 2) Remove the “Locking socket (bayonet)” as in general view and sample chamber bottom from the analyzer and clean in a dishwasher. 3) After cleaning, fix the sample chamber bottom into place again on the analyzer using the “Locking socket (bayonet)” as in general view.
Disposal Disposal The packaging is made of environmentally friendly materials that can be used as secondary raw materials. If you no longer require the packaging, you can dispose of it free of charge in Germany through the VfW dual system (contract number D-59101-2009-1129). Otherwise you should dispose of the material in accordance with the waste disposal regulations that are applicable in your area. The equipment, including accessories and batteries, does not belong in your regular household waste.
