Principle of complex graduation of a portable gas chromatograph with a photoionization detector for geochemical prospecting of hydrocarbon deposits

The results of formation of the calibration concentration of equilibrium vapor of toluene in the field conditions by the method of single extraction under static conditions are presented. The method of current adjustment of calibration of gas chromatograph is substantiated taking into account instability of light flux of electrodeless vacuum ultraviolet lamp of photoionization detector.
