We have a GC-QP2010, where we have attached a pyrolizer. Beacuse of the nature of the analysis of different research groups, we have to be switching between columns. A couple of days ago, i switched off and vent the vacuum to be able to change the column. After plugging in the column, I started the vacuum with the autostart up option and it would start normally but after a few minutes it will show up an error that says "[0da9] High Vacuum Error (turbo molecular pump 1) and it will vent it again. I tried checking it for leaks and even tried to place back the original column to see if one of the columns was the problem with no success. I must say that its a new gc and also a new pump.
