Could you suggest a column for alcohol GC FID analyses?
We produce pure ethanol from corn(99,9%),I analyse it a Shimadzu GC 2010;FID.
Some costumer requires very special ethanol product (Apr.Ph:4!),and the manufacture of columns doesn't suggest it,because it's damage the column.
I use Restek RTX-1701 column,( Crossbond 14%;cyanopropylphenyl, 86% dimethyl polysiloxane) 30 meter;0,25 mmID;1 nm df.
If I inject ethanol which ph is very low,the separation will be very poor...Has someone's experience in this case?
Thank you,
Aniko
