ProSteel, deactivated or Fused Silica, deactivated Which transfer line is preferred?

Question

We intend to test for residual solvent in our product. We have a 7890B GC with a 7697A HSA. Which transfer line is preferable? Is some type of liner needed for the ProSteel line? At what temperature is a liner necessary?

Hello gobirding , 
 
 Specifically for the residual solvents analysis I cannot give you an answer, I am not familiar with that. 
 
 However, if you plan on using a ProSteel transfer line, please take into consideration the information at page 66 of the following manual. 
 I am a bit confused about the liner question. What inlet are you using? If it's a split/splitless for example, a liner is always necessary. Depending on the type of analysis, different part numbers would be required, but a liner is always necessary.

Hi gobirding, 
 I would use Ultimate FS tubing for the transfer line, otherwise follow the comment from CMZainea about the manual describing how to use Prosteel transfer lines, but it is not necessary and the deactivation on FS is normally better than on Prosteel. 
 You will always need a liner in the injector unless it is a valve injection, use an UltraInert one.
