re there any items that the
analyzer cannot test
?
Do not test the following materials.
1. Explosive material, flammable material, and material that
becomes hazardous when heated.
2. Material that forms a surface membrane when heated
because the outer surface dries first. This may raise the
internal pressure and cause the material to rupture.
3. Unknown material and material with unknown
characteristics.
6
What is minimum sample
weight?
The MS/MX/MF/ML can measure samples from 0.1g. When the
sample amount is sufficient, the LCD displays a sample mark.
7
What is maximum sample
weight?
The MS and MX/MF/ML can measure samples up to 71 g and
51 g, respectively.
The LCD displays an “E” if a sample is heavier these values.
8
Is it true that the larger the
sample, the more accurate the
measurement will be?
No. A larger sample may not get heated evenly on the inside o
the heating time may become longer. In such cases, it may not
be possible to achieve high accuracy (repeatability).
9
Can the analyzer measure low
moisture samples (1% or
less)?
The moisture mass of a sample with a moisture rate of 1% or
less may be too low to accurately calculate the moisture
content.
The following chart lists the required sample weights for
estimated moisture contents.
Estimated moisture content Required sample weight
0.1% 20 g or more
0.5% 5 g or more
1% 2 g or more
10
Does placement of powder
samples affect measurement
results?
Yes, it affects moisture content results and repeatability.
ccurate measurement requires even heating and
vaporization, and poor sample distribution can negatively affect
the distribution of heat to the sample.
lways place samples on the pan evenly. (See diagram.)
Overheating and uneven distribution cause uneven heating and
prevent complete drying.
