retention time of HF in Hayesep

[tigerk2001]

Hi,
What is the retention time of HF in HayeSep D column? Is it before or after CO2?

Also, what is the retention time of SiF4 in HayeSep D column?

Thanks for your help

Regards

You won't get a reproducible RT for HF on a porous polymer column.

HF reacts with the support.
