Accurate analysis of difficult samples
The water content of some samples cannot be determined directly with titration. For such cases, Metrohm offers various techniques that allow you to prepare samples for coulometric or volumetric water determination. For difficult samples that have poor solubility or side reactions with the KF reagents, the oven method is ideal. Our high frequency homogenizers enable you to analyze hard, solid samples obtaining consistent results.
