Determination of benzene, toluene, ethylbenzene and xylene in stationery
Determination of benzene, toluene, ethylbenzene and xylene in stationery Details:

Name: Capillary Column
Specification: 60m*0.25mm*1.4um
Model: HH-VRX
Application: Determination of benzene, toluene, ethylbenzene and xylene in stationery gas chromatography

After the sample is prepared as a test sample, it is injected into the gas chromatograph. After the benzene, toluene, ethylbenzene, o-xylene, m-xylene and p-xylene are completely separated from the coexisting substances in the capillary chromatographic column, they are detected by hydrogen flame ionization. Measured by the internal standard method and quantified.

Gas chromatography test conditions:
a) Chromatographic column: polydimethylsiloxane capillary column, 60m×0.25mm inner diameter×1.4μm film thickness;
b) Inlet temperature: 235℃;
c) Column temperature: keep the initial temperature at 50℃ for 1 min, then increase at 8℃/min to 150℃ for 2 min, then increase at 20℃/min to
250℃, keep for 5 min;
d) Detector temperature: 260℃;
e) Carrier gas flow rate: 2.0mL/min
f) Split ratio: split injection, the split ratio is adjustable.
