Determination of the purity of industrial toluene by capillary column
Capillary column to determine the purity of industrial toluene Details:

Name: Capillary column

  Specification: 50m*0.32mm

  Model: HH-JB50

  Application: Determination of industrial toluene purity by gas chromatography


This standard specifies the principles, sampling, reagents, instruments and materials, preparation work, test procedures, calculation of results, and precision of hydrocarbon impurities in coking toluene. This standard applies to the determination of hydrocarbon impurities in coking toluene, including benzene, C8 aromatics and non-aromatic hydrocarbons up to n-nonane. The measurement range for each group of impurities is 0.01% to 0.03% (mass fraction).

Tengzhou Haohan Chromatography Instrument Technology Service Co., Ltd. has developed a HH-JB50 capillary column for toluene analysis with high column efficiency, good separation, effective separation of impurities, accurate and reliable quantification.
