I am trying to create method for vinly chloride in MeOH (GC-FID) and i did it but disturbing is that:
-with every next inj peak area of VC is lower (on the same method's parameters) for example: first inj area is about 200, next 180, next 150... FOR THE SAME CONCENTRATION.
-with every next inj peak has faster RT.. it is few sec but putting 3 or 4 chromatograms on i can see it clearly.
Method is short - it has only about 7 min. I know that VC is volatile but maybe is also another reason? Have anybody any solution for that problem, colud anybody please help me?
