Hi there,

I'm using shincarbon ST packed column 80/100 2 meter, 2mm ID, agilent. I'm going to measure:
(N2, C1, CO2, C2, C3, iC4, nC4, C5,C6)
I have TCD series with FID.
can you please let me know what is the best Inj T, Det temperatures and if you know the Temperature programs and flow rate.
I couldn't see C4 till C6 for 1hour !!

mhhm110,

Might I suggest you go to a Plot Q or some such? Your fixed gas separation is not that challenging (N2 vs. C1) while you heavy end is really too heavy for a ShinCarbon. I would suggest, perhaps, a 60 m RT-QPlot. Your other issue will be water, by the way.

Best regards,

AICMM
