I have already read the articles proposed by you. There is nothing about the effects of contaminants, for example. For companies the suitability test is enough to justify the quality of the carrier. Any suggestion?

Thanks a lot.
Kind regards,
Anna

Hi Anna
Your concern on purity of carrier gas is appreciated.Please find links of three articles which were published earlier. Hope you will find the information useful.

I am GMP inspector and I would like to share with you my experience with you about the quality of the carriers used for GC.
During my inspections, I rarely see a QC lab testing the carriers. It is very hard to explain to the companies the possible impact of the quality of the carriers on the quality of the analytical results. I had several occasions to talk about it with GC experts, all of them agree with me; however, I cannot find any scientific published article nor an official reference about it to support the relevance of the carrier test. Could you kindly give me any suggestion, please?

Thanks a lot

Anna

Hi, This is based on simple stociometry ie. how much Hydrogen will need how much Oxygen to completely react and form water.

Hello Krishna,
Please go through the article “How to read a chromatogram”. Hope you will get your answers.
