Potentiometric and karl fischer titrators

摘要

Potentiometric and Karl Fischer titrators are discussed. JM Science, Grand Island, NY, offers two models each of coulometric and volumetric titrators manufactured by Aquascience. The AQ-2200 Karl Fischer Coulometric Titrator and AQV-2200S Karl Fischer Volumetric Titrator are designed with automation and upgrade capabilities. the Karl Fischer Moisture Titrator MKA-610 from CANNON Instrument Co., PA, which measures moisture in the 10 ppm to 100% range, and includes several convenient features. Metrohm's Dosino? reagent dosing technology promotes precision in titration. The Dosino? sits on the top of the reagent bottle and doses reagent from the top down, preventing leaks and air bubbles. The Metrohm 874 KF Oven Sample Processor automates moisture measurements using titrators such as the Metrohm Titrando 890 or 901.
