I am new to the Shimadzu GCMS-QP2010 Ultra. The machine passed a system check report, and then I tried testing acetone injection with a DB-5 column. After ~2-3 minutes, when the column temperature starts rising above the initial 100 deg. C setting, the purge flow rises above its initial setting of 3 mL/min, and a "CAR1 purge leak" warning is displayed. If I reset of ignore the warning, it will return within ~1 min, and the purge flow will continue increasing above 14 mL/min.
Tightening the column did not help. I will try reconnecting the column.
How can I troubleshoot this issue?
