Page 7: Preparing Moisture Analyser To Work
USER MANUAL 7. Preparing moisture analyser to work During heating, the halogen heaters 1 warm up to very high temperature. When drying chamber is opened avoid touching the heaters as it may cause severe burns or damage the heaters! Dryer chamber cover 3 heats up to 40°C, but perforated cover may heat up over 60°C. - Page 8 USER MANUAL After self-tests and result stabilisation zero indication is displayed. The dryer starts initial heating (signalised with an appropriate communicate). After initial heating the moisture analyser is ready to work. When temperature during initial heating exceeds 105°C or heating time is longer than 1 minute, terminate initial heating with CLR key and check if the temperature sensor 2 works properly and if both halogen heaters light 1 (see chapter 15).

Page 10: Description Of Thermogravimetric Analysis
Methods of determining moisture may be grouped in two main categories: absolute and deductive. Absolute methods are based on simple relations, e.g. weight decline during drying. Thermogravimetric analysis used in AXIS moisture analyser is an example of this method. Deductive (indirect) methods measure physical quantity related with moisture, e.g. -
Page 11: Drawing And Preparation Of A Sample
USER MANUAL 10.3 Drawing and preparation of a sample As sample of given substance must be representative, drawing and preparing a sample is very important process as it affects repeatability of measurements. The most common method of homogenizing a sample is mixing. The other method is to draw few samples from different but specific points in a substance and calculate an average value. -
Page 12: Glass Fibre Filter
USER MANUAL Attention: Due to temperature sensor localisation, max sample height is 10mm. When substance ply is too thick, surface layers will be heated too much and internal – not enough. This may result in burning the sample or surface incrustation, which will make drying process difficult and measuring result false. -
Page 13: Other Practical Notes
USER MANUAL 10.9 Other practical notes It is preferable to work with the same mass of the sample at each measurement to measure the size of the sample in a reproducible way. It is best to use the same instruments for the application of the sample. Put a sample on the pan as quickly as possible to avoid losing moisture. -
