JM Science announces their new AQUACOUNTER® Karl Fischer Coulometric Titrator (AQ-2200S). This new high-end titrator with its excellent capability and upgraded performance is ideal for the trace level water content determination in lithium-ion battery materials with high accuracy using coulometric Karl Fischer titration. Lithium-ion batteries are one of the most popular for portable electronics due to their good energy-to-weight ratios, no memory effect and a 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. The new 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 an accuracy of =10µgH20. The new cell design allows for easy assembly and maintenance. The new 7.5-inch color touch screen is easy to read and operate. It has enhanced memory capacity and user may store results on a USB?memory stick. The stored data can be read out on the color display. Result data with curves may be viewed on a PC internet browsing program with optional software. This titrator comes equipped with a built-in thermal printer with easy paper loading and high resolution printouts. It can be used with peripherals of previous versions.
