FAQ
Karl Fischer buffers and reagents are used to measure water content (moisture) in liquids and solids by KF titration. They support stable reaction conditions, clear endpoints, and repeatable results. Popular options include formulations from Fisher Chemicals, Honeywell Fluka, Honeywell Research Chemicals, and JT Baker for routine QC and method development.
Choose coulometric reagents for low water levels (trace moisture), where generated iodine enables highly sensitive measurement. Use volumetric reagents for higher water content ranges and faster throughput with direct titrant addition. Selecting matched anolyte/catholyte or composite reagents from Honeywell Fluka or Fisher Chemicals helps maintain consistency across instruments and sample types.
Drift control often improves when you use fresh, properly matched KF solutions and limit moisture ingress. High-quality anolyte/catholyte pairs or composite volumetric reagents can help stabilize baselines and endpoints. Many labs standardize on well-known product lines from Honeywell Fluka, JT Baker, or Fisher Chemicals to improve repeatability across operators and sites.
Store KF reagents tightly sealed, away from humidity and heat, and follow the manufacturer’s guidance for temperature and shelf-life. Minimize bottle opening time and use dry handling techniques to avoid water uptake. Using consistent supplies from Fisher Chemicals, Honeywell Fluka, or JT Baker helps maintain method control and reduces troubleshooting from aged or contaminated reagent.
In coulometric KF titration, the anolyte and catholyte support the electrochemical generation and consumption of iodine. Using the correct pairing helps maintain conductivity, stable reaction conditions, and accurate moisture results—especially for challenging matrices. Suppliers such as Honeywell Fluka provide dedicated coulometric solutions (including oven variants) to match common instrument setups.
Start by matching your method type (coulometric or volumetric), your sample introduction (direct or oven), and your instrument recommendations. This category includes widely used solutions and composites from Fisher Chemicals, Honeywell Fluka, Honeywell Research Chemicals, and JT Baker. Filter by brand and compare formulations to align with your SOP and target moisture range.
