An analyst loads a blood alcohol sample onto an instrument equipped with a single column and FID detector.

The run is completed and the analyst recaps the vial and places it on a second headspace unit connected to GC-FID with the confirmation column. What is the problem with this approach?

concentration will not be the same. A fresh sample is required.
