GC Column to measure Ethylene

Hello everybody, good morning

We intend to measure ethylene on a GC-2014 SHIMADZU.


Isotherm: 40 ° C

Injector temperature: 120 ° C

Detector temperature: 250 ° C

Run: 2 minutes

Carrier gas: Helium

Helium Pressure: 30 psi

Hydrogen pressure: 10 psi

Oxygen pressure: 5 psi


The idea is to find an ethylene column for GC-2014 SHIMADZU with the shortest possible detection time. Times longer than 4 minutes, the measurements become not very viable due to the large number of samples being evaluated.
