Karl Fischer reagent that can accurately measure moisture in lithium-ion secondary battery (LiB) related samples.
If lithium-ion batteries (LiB) contain moisture, it can lead to the generation of hydrofluoric acid and gases, potentially causing a decrease in battery capacity, product damage, and swelling. Additionally, it can affect the lifespan, making moisture measurement in lithium-ion battery (LiB) electrolytes important from a quality control perspective. Lithium-ion battery materials are samples where accurate moisture measurement is difficult due to side reactions with alcohols such as methanol. However, the Hydranal NEXTGEN Coulomat A-FA / C-FA series uses alcohol-free Karl Fischer reagents, allowing for accurate moisture measurement even in samples containing lithium-ion battery electrolytes and additives, which have previously posed challenges for moisture measurement.

Company information
Since its establishment in 1904 (Meiji 37) with the aim of manufacturing and selling chemical products, our company has been actively engaged in production and sales activities to contribute to various industries through research and development and production. We provide not only reagents for testing and research but also custom reagent preparation for specific applications, liquid preparation services, and contract services for organic synthesis. In recent years, we have specialized in small-scale production of research reagents related to pharmaceuticals, metabolites, functional materials, and environmental substances, and we propose contract synthesis of hard-to-obtain minor compounds to various institutions. In 2016, we signed a general agency agreement with Honeywell (Honeywell Japan Ltd.) for sales in Japan, particularly expanding our lineup of Karl Fischer moisture measurement reagents, high-purity solvents, analytical standards, and inorganic reagents. In 2019, we launched "Reagent Direct," allowing customers to place product orders and request quotes through our website, as well as check inventory and regulatory compliance, search and download SDS/product specifications/test reports, and access various services and content such as technical articles and evaluation cases. We will continue to respond quickly and accurately to our customers' diverse requests and strive to be a company that contributes to society.
