Analysis of alkane impurities for calibration of gas chromatograph

A set of quantitative analysis method of n-alkane impurities based on gas chromatography is established to analyze and accurately quantify the mutual impurities in n-tetradecane, n-Pentadecane and n-hexadecane, which are common substances used for calibration of gas chromatography, and solve the problem of inaccurate preparation value in the preparation of alkane mixed solution.The method can be applied to the determination of preparation value of mixed alkane solution, The fixed value results can meet the traceability requirements of gas chromatograph calibration.
