Pharmaceutical product quality, effectiveness and shelf life depends significantly on the water content in these products, which makes water determination in pharmaceutical analysis so important.

Routine Karl Fischer titration is the prescribed technique for measuring residual moisture content to monitor process control, sample specification and optimize freeze-drying processes for lyophilized products.

Near-infrared (NIR) analysis offers a number of advantages over traditional instrumental analysis methods including no sample preparation, rapid analysis times and recovery of an intact sample. This technique measures qualitative and quantitative moisture content either inline or at-line reducing over-processing of product and improving production consistency.

While NIR is a more profitable and productive technique in the long run, quantitative NIR analysis requires prior calibration and validation from reference analytical methods. Karl Fischer titration provides the necessary foundation to build and validate this calibration. Learn how choosing the proper technique and sample handling procedure greatly improves the repeatability and accuracy of Karl Fischer titrations and leads to faster NIR implementation for both lab and in-process measurements.
