GC Agilent 7890B-TCD -PDHID-FID

Hello,

Unfortunately Agilent can't have a third detector when a PDHID is present, so it is not a valid configuration.

For the PDHID, UHP helium is required, and additional a main getter and mini getters are used for additional helium clean up.  Getters remove all impurities with the exception of argon.

Typically with complex system like this we would use a channel partner.

Thanks kelly

Why PDHID is not valid with third detector in 7890B and what is the suitable second detector with Pdhid?

What do you mean by partner channel?

As I know from Agilent agent that this system configurated with three detector each detector in separate channel even I can change carrier gas of one channel with same carrier of other channels I.e. Tcd with argon and PDHID and FID with helium .

Please confirm that if system has separate channel it will be valid
