Crude sodium borates for industrial use — Determination of total and alkali-soluble calcium and magn...
A test solution is prepared by one of the two following ways: a) fusion of a test portion with sodium carbonate in the case of total calcium and magnesium contents, and b) from an aliquot portion of "solution A" (ISO 2217) for alkali-soluble calcium and magnesium contents. Lanthanum ions are added to the solution to suppress certain interferences. The solution is aspirated into an…

Spices, condiments and herbs — Determination of volatile oil content
Describes a method the principle of which consists in distilling an aqueous suspension of the product and collecting the distillate in a graduated tube containing a measured volume of xylene to fix the volatile oil. After separation of the organic from the aqueous phases the total volume of the organic phase is read and the volatile oil content is calculated after deduction of the volume of…
