What is the difference between MS/MX/MF/ML and Karl Fischer type analyzer?
1. MS/MX/MF/ML is a heating and drying method analyzer that compares weight before and after heating and drying, while a Karl Fischer type analyzer titrates KF reagent that contains iodine to sample electric-chemically. 2. Karl Fischer method enables a measurement from some ppm to 100% (water), but operation is complicated and the unit is expensive. MS/MX/MF/ML is very easy to handle, needs short time to measure and is reasonably priced. 3. Where required resolution is under 0.01% MS/MX is more suitable in terms of handling, accuracy and running cost. There is no difference between data obtained with the Karl Fischer method and heating and drying method; however MS/MX is more likely to have better repeatability than a Karl Fischer type.
