METHOD OF SAMPLE PREPARATION OF BIOORGANIC SAMPLES Russian patent published in 2015 - IPC G01N1/28 B01D59/44 H01J49/34

Abstract RU 2560066 C1

FIELD: biotechnology.

SUBSTANCE: invention relates to a method of sample preparation of bioorganic samples, including medical ones, for determining in them of isotopic ratio ¹⁴C/¹²C and ¹⁴C/¹³C using accelerative mass spectrometer (AMS). The method comprises oxidizing carbon contained in bioorganic sample to carbon dioxide. Oxidation is carried out in the liquid phase, at that the oxidizing agent is used as hydrogen peroxide, and the catalyst - as zeolite of type ZSM-5 with iron-containing active component. Carbon dioxide released as a result of oxidation is sent for analysis on the accelerative mass spectrometer AMS.

EFFECT: expanding the range of substances analysed for the isotopic composition of carbon.
