GC Column to measure Ethylene

Question

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.

Hi mcarito,

any news here?

If not I'll take a wild guess and give you some options to check out:

A01425 = https://www.agilent.com/cs/library/applications/A01425.pdf on PoraBOND Q
A01610 = https://www.agilent.com/cs/library/applications/A01610.pdf on PoraPLOT Q
A00440 = https://www.agilent.com/cs/library/applications/A00440.pdf on PoraPLOT Q

451C = https://www.agilent.com/cs/library/chromatograms/451C.jpg on HP-PLOT Q

Under 4 minutes should work if not a lot of higher hydrocarbons are present.

Norbert
