I just started a job at a beverage processor in their analytical lab and I'm being trained on their GC's. I used one maybe 10 years ago in school but not since - I might as well say I've never used one as I don't even remember it.
When I'm drawing my standards with the 100 microL syringe, I get a tiny bubble at the end of the plunger and am having a difficult time knocking it off. I'd imagine that this bubble is displacing part of my sample size if I can't remove it correct?
Any tips? What I was shown was to turn the sealed standard vial upside down and draw the sample upside down by holding the vial and pulling on the syringe plunger past the 100uL mark and then "flick off any bubbles". Maybe it just takes practice? Thx for any advice.
