CP 3800 Keypad issues
I've had to replaced the keypad on our instrument several times in the past year. We only need to start/stop the GC because we are acquiring the signal with an Agilent 35900E A/D box and Agilent software. Is there a way to install a simple button/switch to start/stop the GC?

EFC Module
We Use CP-3800 for 10 years. recently while swiching On GC, A message appears momentarily " Remove or repair EFC Modules"

We plan to replace Type 1 EFC-21 & EFC-24.

Could you give me Part No and Aavailable source or any alternatives of this product ?

Progressive reduction of signal
We have two Varian CP-3800 GC units. In the analysis* with TSD (GC1) and TSD or FID (GC2) both chromatographs show a progressive reduction of signal in the detection of nicotine during the day (for example, using TSD in a day the initial ABC is 1000 in the morning and the final ABC is 800-900 in the afternoon). Because both chromatographs are showing the same problem and share the main gas supply lines, we verify and there are no gas leaks.*Using very similar methods: same capillary column type, program temperature, standard solution (fresh or old), solvent, etc.

Does anyone know why this is happening?
