METHOD OF DETERMINING LIGHT ELEMENTS IN LIQUID SAMPLES Russian patent published in 1995 - IPC

Abstract RU 2045047 C1

FIELD: analytical chemistry. SUBSTANCE: known amount of sample of liquid material is changed preliminary to solid condition by cooling in special dish, which is filled with thermo-accumulating material, which material keeps low enough temperature of the sample. Samples of light volatile liquids are dissolved by solvent, which increases temperature of hardening of tested sample; the solvent does not include elements to be determined. Analysis has to be done according to internal or external standard method. EFFECT: improved precision. 2 cl, 1 dwg, 1 tbl
