Protocols

Summary application report for analysis of moisture in sulfuric acid

This protocol describes a one-component Volumetric Karl Fischer Titration method for the determination of water content in Benserazide hydrochloride.

Summary application report for analysis of moisture in D(+)-glucose-monohydrate

Foodstuffs encompass the most diverse products. Depending on whether carbohydrate-rich, fatty or proteinrich substances are under investigation, different working techniques are favourable. Complex matrices that dissolve slowly, or where the water can only be slowly extracted, necessitate the use of solubilisers.
