Hello,

 

Today i checked the pressure regulator, which are connect to our GC System.

 

We got 5 GC`s in our lab.

I checked the pressure regulators.

They all got different values.

 

7890B N2 =  4.2 bar       N2 = 3.4 bar

            Ca =  5.0 bar      Ca =  5.0 bar

            He =  4.0 bar       He =  4.2 bar

6850    N2  = 3.2 bar        N2 = 4.4 bar

            Ca =  5.2 bar        Ca = 4.6 bar

            He = 4.6 bar        He = 1.2 bar  H2 = 0.8 bar

7890A N2 = 4.6  = Headspace

            Ca = 4.8

            He = 4.4

            H2 = 4.2

 

I think the 6850 with 1.2 / 0.8 is turned of on purpose.

Should it be around 6 bar for every pressure controller. 

 

 

 

 

Thank you
