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.
本文介绍了一种用于在各种介质中分析芳烃时校准气相色谱仪的精密装置。该装置包括一种基于环氧树脂的聚合物模板,通过聚乙烯多胺冷冻固化。作者提出并测试了插入聚合物模板中的芳烃的最佳组成。结果证明,所建议的装置能在至少1.5年内保持气相色谱仪的稳定校准,而在连续工作3个月期间,芳烃的现有浓度与平均值的偏差为3.5-7.5%。
