Product DescriptionSpecial chromatographic column combination, central cutting and back blowing technology and FID technology were used to detect benzene homologues. After the sample is collected in the quantitative ring, switch the injection valve, and under the drive of carrier gas, the samples enter the chromatographic column respectively for separation. Benzene, toluene, ethylbenzene, xylene, styrene and cumene enter the analysis column through the pre column, and then enter the FID detector for separation. After switching the position, the heavy hydrocarbon components are blown back and vented.
