How to Determine Whether a Karl Fischer Moisture Analyzer Can Measure a Substance's Moisture

Karl Fischer moisture analyzers are used mainly for moisture testing of liquids and gasesandas well as soluble solids; combined with a Karl Fischer oven, they can also measure moisture in insoluble solids. It is an internationally accepted method, also known asthe "absolute method". Its features—convenient operation, high precision, and good accuracy—make it widely used in chemicals, pharmaceuticals, food, materials, electric power, petroleum, new energy, and other fields; almost any project that requires moisture measurement involves a Karl Fischer moisture analyzer.

Karl Fischer moisture analyzers cannot test conductive or magnetic substances，because these easily short-circuit the electrodes and give inaccurate results. For uncommon reagents or powders, customers may also worry about chemical reactions with components of the electrolyte that distort the measurement. There is a very simple way to check: measure with the Karl Fischer moisture analyzer3 times and observe the results—check the repeatability and whether the displayed measurement reaches the endpoint quickly. If the results are unsatisfactory, the substance may not be suitable for Karl Fischer testing.

Jiangsu Victor Instrument Meter Co., Ltd. recommends theWKT-A8 "fully automatic" Karl Fischer trace moisture analyzer. The VicoMeter WKT-A8 uses the Karl Fischer coulometric (electrolytic) principle to rapidly determine trace moisture in samples, measuring moisture down to 1 ppm (0.0001%) and determining trace moisture in solids, liquids, and powders within 1 minute. The instrument has a built-in printer, can store 600 data records, and supports real-time query and printing! Its biggest advantage is automatic reagent addition and automatic waste discharge, keeping operators from direct contact with reagents and protecting them from volatile reagent vapors. The instrument complies with multiple national and international moisture measurement standards and has four built-in moisture calculation formulas to meet the moisture measurement needs of every industry.
