I have issue with my method on HS-SPME, the ISTD that I use shows inconsistent results! I spiked 3 samples to check recovery of them and ISTD is different in all those 3! sample matrix and every thing is the same. I desorb the fiber for 8min on column and after have 5min post desorb conditioning.
Is it the fiber? what I'm missing?
Your help is highly appreciated.
Thanks in advance.
