Hello,

I have need to have a confirmation on a choice of capillary column.
I would like to make the analysis of THT (tetrahydrothiophene) - 5 ppm - in natural gas.
I thought to a HP-PLOT Al2O3, what do you think?

Thanks,
Mary

Hi,

You better stay with a thick film HP-1 or DB-1 as at low concentration the PLOT column is not the best choice

Thank you Fawk
