Hi

I was wondering if anyone can recommend a column and supplier for me. I require a the following column and am having trouble finding one…

Material: Glass
Size: l=2m, =2mm
Stationary Phase: ethylvinylbenzene-divinylbenzene copolymer (136-173 m)

Any guidance will be appreciated.

Thanks

Sound like a Porapak Q or another Porapak column, as several of those are
ethylvinylbenzene-divinylbenzene copolymers.

Should be available from most suppliers, but you will need to specify which Porapak.

Thanks for the lead, i will look into the Porapak

And remember to identify your GC and injector options as glass columns are not universal
