ABSTRACT:
A method of detection of chromatographic peaks in gas-liquid or gas-solid chromatography, comprising the ionization of the organic or metallo-organic compounds separated in a chromatographic column and removed in the form of fractions out of the column by an inert gaseous carrier. The ionization of the above compounds is effected by way of burning them in the flame of formic acid vapours. Simultaneously with the ionization, chromatographic peaks are recorded by means of the electrometric method based on measurement of the increase in the degree of the ionization of the flame as the above organic or metallo-organic compounds are being introduced thereinto.
