Hello
Recently we face problems with Air in our GC/MS. When i perform the Air&Water Check if only the MSD is connected with the splitter and two plugs the Nitrogen and Oxygen counts are around 3 times higher. Does anyone has an idea where possible air leaks can occur in the MSD?
One year ago we had to change the transfer line because it was damaged and caused an high air leak. I already checked the side plate O-ring and the Vent- Valve-ring without any signs of damage.
Current Params used: etune.u
Relative abundances:
18/69 = 1.83 Water% (counts=35504)
28/69 = 83.18 Nitrogen% (counts=1614848)
32/69 = 24.67 Oxygen% (counts=478912)
44/69 = 0.48 Carbon Dioxide% (counts=9312)
28/18 = 4548.36 Nitrogen/Water%
