Coulometric Karl Fischer Moisture Titrator with Integrated Headspace Oven for Battery Materials

Product Overview

This high-performance coulometric Karl Fischer moisture titrator integrates an advanced coulometric titration module with a precision thermal headspace extraction oven into a unified, space-saving architecture. Specifically developed to meet the rigorous quality control and research standards of the modern battery industry, the equipment provides comprehensive trace moisture detection across liquid, solid, and gaseous samples. Capable of analyzing moisture contents ranging from 1 ppm to 100% (absolute water mass from 3 μg to 199 mg with 0.01 μg resolution), this system eliminates sample matrix interferences by thermally releasing moisture and transferring it directly into the titration cell via a sealed, dry inert carrier gas stream.

Engineered for streamlined deployment across battery manufacturing workflows, the unit is widely utilized for moisture determination in positive and negative electrode active materials, coated electrode sheets, polymeric and ceramic-coated separator films, and non-aqueous liquid electrolytes. Its compact footprint makes it exceptionally well suited for integration into dry rooms or standard glovebox environments, where space optimization and inert atmosphere handling are critical. By preventing direct contact between complex sample matrices and the Karl Fischer reagent, this system ensures extended reagent life, minimizes baseline contamination, and delivers uncompromised analytical throughput.

Built for demanding research and round-the-clock industrial quality assurance, the instrument features intelligent drift adaptation, automated vial piercing, and programmable multi-stage temperature profiles. Operators can rely on stable baseline balances and exceptional measurement repeatability (≥99.7% at 1000 μg H₂O), ensuring that trace water levels—which are critically detrimental to battery cycle life, solid electrolyte interphase (SEI) formation, and cell safety—are quantified with absolute certainty.
