Vegetable products — Determination of chloride content
The method consists in precipitating chloride by addition of an excess of a standard volumetric silver nitrate solution and titrating this excess with a standard volumetric potassium thiocyanate solution. If the product contains natural anthocyanin pigments, the method is applicable with specified modifications.
Cryolite, natural and artificial, and aluminium fluoride for industrial use — Determination of sulph...
Covers a method, the orinciple of which consists in preparing tablets from a mixture of the test portion and a binder and measuring the intensity of the K line emitted by the sulphur. The measured intensity is then compared with the intensity of emission of standard tablets of known sulphur content. The method is applicable to products having sulphur contents between 0,01 and 2 % (m/m).
