Im running on an old GCMS with headspace sampler. Its been failing during runs recently. The logbook shows that the oven is not ready at run time for each sample. After about 10 samples it just stops collecting data. The headspace continues to cook all of the samples. At the end of the sequence it will report "Tray motor error [Async error #1]" and then "Lost connection to Agilent G1888 Headspace Sampler at 10.1.1.103". Any idea how to troubleshoot or solve this issue. I currently have a new belt to replace on the HS, as I have noticed that it seems to get stuck around vial 13, and the HS never resets at the end of runs, it attempts to rotate back to vial position 1 but gets stuck around the turns. Now turn if this is a belt issue, or maybe connection issue. We have had a lot of problems with the HS connecting to the computer. Maybe needs a new wire or something?
