I'm having an issue with my carrier gas which is causing the instrument to go into error mode.
PTV: 200C, splitless 1uL
Column: Carbowax 25m x 0.25mm x 0.20um
FID: 300C
Carrier: Helium at 2mL/min
Start the oven programme at 50C and carrier flow is stable. As soon as the oven gets to 100C, carrier gas flow drops to 1.2mL, oven reaches 200C and flow drops to 1mL with error and standby mode activated.
Can anyone offer any ideas? Liner, septum changed, column refitted.
Thanks in advance!
