low moisture content evaporation (under-dried 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” 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.
17.2.4. Selecting drying mode
The software of moisture analyzer MA 3Y series
enables selecting one of four drying modes:
•
Standard
•
Quick
• Mild
•
Step
STANDARD mode
Standard mode is the most frequently used of all
drying modes. It enables accurate determining of
moisture content is a dried sample.
MILD mode
Mild mode 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 mode prevents from decomposing of substances sensitive to
heat by mild temperature increase in set amount of time (time interval has to
