KF Coulometric Titrator for Trace Water in Battery Materials

JM Science has announced their AQUACOUNTER® Karl Fischer Coulometric Titrator (AQ-2200S). This new high-end titrator is ideal for the trace level water content determination in lithium-ion battery materials using coulometric Karl Fischer titration. Lithium-ion batteries are popularly used in portable electronic devices due to their good energy-to-weight ratios, no memory effect and slow loss of charge when not in use. Elevated levels of water content in three primary functional components (anode, cathode, electrolyte) may cause degradation in capacity and may reduce the overall lifetime of batteries.

It will be of interest for users who: 1) have many kinds of samples to be analyzed; 2) exchange KF reagents frequently or after each measurement; 3) are eco-minded and budget-conscious.

This titrator allows two titration stations to run parallel with various coulometric/volumetric combinations. With both a volumetric and coulometric channel, one can measure moisture over the entire range from 1 ppm to 100% or double your sample throughput with 2 identical KF stations. This design is economical and ecological because it reduces the use of expensive KF reagents. Three types of electrolytic cells are available including small volume, standard, and one-room cell. There is an ultra-trace moisture measurement mode equipped in this titrator with a measuring range of ≤10µgH20 ~ 99mmgH2O. It has enhanced memory capacity: Internal memory 100 data / channel; USB flash memory >=256MB; Max. approx. 9900 data. Current status, data and function keys are displayed on a 7.5-inch color-touch display. Result data with curves may be viewed on a PC internet browsing program without optional software and it comes equipped with a built-in thermal printer with easy paper loading and high resolution printouts.
