Filters ensure equal liquid distribution or in case solid materials avoiding burning a sample 11 8 Selection of drying parameters to the sample material Selection of proper temperature and drying time is essential to achieve precise humidity measurement Drying parameters are selected properly if repeatability is on satisfactory level usually between 0 1 1 Parameters choice should be made in 3 steps Step 1 Drying temperature is related to the physico chemical properties of the sample It is determined by the number of tests carried out in several successive temperatures e g at intervals of 10 C Proper temperature is the highest value for which the sample for a few minutes does not change color and smell Changing the color or odor indicates the start of the oxidation of the sample which changes the properties of the sample which usually affects the measurement accuracy Step 2 Weight of sample used should be large enough to use the entire surface of the pan however the thinner the layer of sample the better the drying process proceeds The top and bottom layers of the material should be dried similarly at the same time If the material is covered with shell and some moisture is trapped in the material user should disintegrate the material or reduce the drying temperature For liquid materials is preferable to use filter which accelerates the drying Step 3 Select drying time to chosen mass of sample To do this set the mo
