I am working with a lot extremely air/moisture sensitive chemicals for assay or concentration analysis. Samples were prepared in a glove box and then manual injected into the GC.
To minimize the decomposition, I am seeking a way that will prevent samples from exposing to air during the injection, such as setup a transferline for injecting sample in the glove box, or install a encloser to a autosampler, then purge the system with inert gas........
Injecting this type of chemicals, syringes were found very problemetic too. After few times use, it will already cause severe sample decomposition (I rinsed the syringes with dried solvents before and after injection). Not to mention they die quickly due to the clogging.
Does anyone has any experiences with injecting/handling this type of chemicals? Or any suggestions on building a air/moisutre free system to transfer the samples from vials to GC inlet?
Any help would be greatly appreciated!
