Try Hayesep T. Puts Acetylene after Ethylene and Ethane. For process GCs, ones that do injections automatically, we usually heartcut off Hayes T onto Hayes T.
At Seimens Applied Automation, they routinely do 0-10 ppm (and less) Acetylene in Ethylene in 45 seconds on 1/16" micropacked columns of 100/120 Hayes T.

Dear Bill!
I am very grateful for the answer, but there are some more questions:
1. Why acetylen leaves later, than Ethylene and Ethane?
2. Are available of clause on the similar analyses?
3. What such 1/16?
Yours faithfully and best regards. Nicolas Zamyatin
