8.3. Understanding drying parameters and settings
1.
Drying Temperature - maximum drying temperature which will be used to perform moisture analysis.
2. Mode - The analyzer can be used in two drying modes:
Short Mode (Automatic): Drying is terminated when the mass loss between successive samples
taken during the moisture analysis (Sample Quantity) is smaller than the threshold value of 2mg.
Time Mode – Drying is terminated when user defined time (Drying Time) is reached. The Drying
time can range from 1second to 10 hours.
3. Calculation – results can be calculated and displayed using one of the three formulas:
W [%] = m
0
– m/m
0
* 100%, where moisture is determined in relation to initial weight
W [%] = m0
– m/m * 100%, where moisture is determined in relation to current weight
W [%] = m/m
0
* 100%, where current weight is determined as a percentage of sample weight
Where: m
0
= initial (wet) weight, m = current weight, and W [%] = moisture as a %
4. Samples Quantity – used and required when operating the analyzer in the Short Mode. The analyzer uses the
setting to check whether the mass loss taken between the samples is less than 2mg. Higher number of
samples taken allows for a more accurate determination.
5. Sampling Interval – time separation between each sample taken. This setting is used when operating the
analyzer in the short mode and it can be optionally used in the time mode when tracking the progression in
mass loss of the sample i.e. transmitting the sample mass to a printer or a PC.
