Dear all
I have 6 components to separate: acetone, ethyl-acetate, ethanol, methyl-ethyl ketone, toluene,styrene. Which column is the best choice? ZB-1 or ZB-WAX? These components are in CS2 solvent.
I have tried ZB-1 and ethyl-acetate had 3 peaks instead of one. And the same happened to methyl-ethyl ketone. Is it possible that my standards were contaminated? In addition MEK peaks were interwoven with solvent peak(CS2).
Condition: inlet: 220°C
detector(FID): 280°C
ZB-1 column
carrier gas: nitrogen
Temp. prg: 40°C 8 min, 5°C/min 60°C 18 min.
Thank you for your help in advance!
