[A device for calibration of a gas chromatograph in analysis of aromatic hydrocarbons]

The article deals with the description of elaborated device for calibration of gas chromatograph in analysis of aromatic hydrocarbons in various media. The device includes a polymeric pattern based on epoxy resin, consolidated by polyethylene polyamine freezing. The authors suggested and tested an optimum composition of aromatic hydrocarbons inserted into the polymeric pattern. The suggested device was proved to maintain the stable calibration of gas chromatograph within at least 1.5 years while the existing concentrations of aromatic hydrocarbons deviate 3.5-7.5% from the average value during 3 months of permanent work.
