I have recently started using the MMI on our GC (7890A) -  MS (5975C) for analysis of brominated flame retardants in air samples.  There is a paucity of information regarding use and maintenance of the MMI, and I have run into the problem of carry over from sample to sample - so that my hexane blanks look as bad as the samples themselves.  I would appreciate any help on this matter.
