What is the difference between
the MS/MX/MF/ML and a Karl
Fischer type analyzer?
1. The MS/MX/MF/ML is a heating and drying method analyzer
that compares weight before and after heating and drying.
Karl Fischer analyzers are electrochemical, with a KF
reagent containing iodine being added at a fixed quantity.
2. Karl Fischer method can measure from a few ppm to 100%
water but operation is complicated and units are expensive.
The MS/MX/MF/ML is very easy to handle, measures quickly
and is reasonably priced.
3.
When the required resolution is under 0.01%, the
MS/MX/MF/ML is more suitable in terms of handling,
accuracy and running cost. There is no difference with data
obtained with the Karl Fischer method and the
MS/MX/MF/ML is likely to have better repeatability.

What does a measurement
accuracy of 0.02% mean?
This value represents the variation and repeatability of moisture
content rate data when the same sample is tested repeatedly
under the same conditions. In statistics, this value is referred to
as standard deviation.
