Can Sodium Tartrate Dihydrate be
recycled?
No. Moisture once decomposed from crystal of the sample
by heat cannot be reconstituted.
5
Can anything be tested with the
analyzer?
1. Material that is explosive and/or flammable or fumes
when heated are not suitable to be tested by heating
and drying method. Those materials must not be tested
with the analyzer.
2. Materials whose surface gets dried first and makes a
membrane which makes pressure inside high must not
tested because they may be dangerous.
3. Materials whose characteristics are should not be
tested.
6
What is minimum weight moisture
content rate measured at?
In the case of using MX/MF-50, sample more than 0.1g is
measurable. Sample mark on LCD display will light when
sample amount is enough.
7
What is maximum weight moisture
content measured at?
In the case of using MX/MF-50, sample less than 50g is
measurable. “E” will be displayed if sample is over 50g.
8
Is it true that the more sample used the
more accurate the measurement will
be?
No, that’s not true. Excess of a sample may not get heated
inside evenly or heating time may be longer. In such cases
measurement may be non-repeatable.
9
Does placement of sample such as
powder on a pan affect measurement
result?
Yes. How to put a sample on a pan determines heat
distribution. To measure moisture content rate accurately
even heating and vaporization are needed so sample should
be distributed over the pan.
5. Calibration
No.
Q
A
1
Can calibration of the moisture
analyzer, MX/MF with Sodium Tartrate
Dihydrate be possible?
No. However accuracy check can be done with the sample
since moisture content rate of the sample is theoretically
fixed. Heating and drying method moisture analyzer weighs
sample before and after heating and weight and
temperature calibration is possible.
2
Can a user do weight and temperature
calibration?
Yes (only MX can do temperature calibration). Also, results
of these calibrations can be printed out in accordance with
GLP, GMP or ISO.
1. For weight calibration optional accessory calibration
mass, 20g, AX-41 is recommended.
2. Use optional accessory temperature calibrator, AX-43,
with certificate for temperature calibration.
3
Are traceability system diagram and
certificate of measurement available?
Yes both are available upon request.
1. If it is of analyzer itself, certificate both covers weight
and temperature.
2. If it is of calibrator, certificate is only about temperature
calibration however the calibrator is sold with tracability
certificate and certificate of measurement no additional
charge.
