air leaks message

[leticiahf]

Hi
I am facing a problem in CG (FID) . When I am going to execute a method, the air flow, which would be 400 mL/min, does not reach this value, remaining in 0, and the message " Det APC1 air leaks" appears. What is happening? How can I solve it?

Sincerely
Letícia

The error message simple means the electronic flow control (APC) can't reach the proper pressure or flow reading. This is not always due to a leak, it sounds like you may not have flow into the detector.

so, how to solve the flow into the detector?

Your air supply may be turned off or a tank may be empty.

Check.

best wishes,
