Karl Fischer titrators are specialised analytical instruments used to determine the moisture content in various substances, including chemicals, pharmaceuticals, and food products. This technique employs the Karl Fischer reaction, which quantifies water by measuring the amount of iodine required to react with it in a sample. These titrators can be either volumetric or coulometric, with volumetric titrators suitable for samples with higher moisture content and coulometric titrators ideal for trace moisture analysis. Modern Karl Fischer titrators often feature automated processes, allowing for precise control, real-time data analysis, and user-friendly interfaces for simplified operation. By providing accurate and reliable moisture measurements, Karl Fischer titrators play a crucial role in quality control and compliance in industries where moisture levels can significantly impact product quality and stability.
