Hi, ALL !
I have Agilent 7890 with 2 detectors (FID + ECD). I want to install third detector (NPD).
I know that you can set FID+ECD+TCD. Can I install FID+ECD+NPD? If not, why?
But I can not figure out where to attach the heater and sensor power NPD detector.
Heaters of all device (Inj 1, Inj 2, Det 1, Det 2, and heater MS-interface & sensors) connect to PIN № 21 on the main Board. This PIN is already busy.
PIN № 22 is free. I can connect my heater power cable to this PIN? This is a position 3&11 on PIN22 or 4&12? Where connect thermosensor?
Chemstation program will operate by heating the detector?
Does anyone have pics, looks like the connection 3 detectors to the Main Board? Or manual?

PS: Of coarse, we can attache the power and sensor NPD instead of MS-interface. But this is not exit from a situation.

PPS: Thank you for your attention to my bad english

You can only install the TCD as the third detector at the moment on the 7890. It is installed on the left side of the GC oven.

Russian,

A minor addition to GasMan's comments. If I am not mistaken, you can also install an Analog input board as the "third detector". Thus, if you have an independent third detector (temp control for the base, analog out, etc...) you could install the NPD as the third. For example, if you had a stand-alone DET NPD you could use the analog in to get your data into Chemstation.
