Ammonia analyzer problem.

[12buckle]

This is an applied GC that I run on a weekly cal. For some reason my baseline has gotten very noisy. It still reads correct results on cal. But the base line is just noisy. I'm scared to dig into it because it is working. I don't wanna mess it up. Any suggestions?

PID
ITC

12buckle,

Who makes this GC? Anything change recently, the gases or pressures? When was the last time maintenance was done on the detector?

Best regards,
