Dear Dominique
Sample absolute calibration may not be apploed bu using a cerified gas which undergo a different analytical path from your unknown samples.
For interface characterization you can use a generic h2 cylinder.

Dear all

 

I’ m looking for H2 reference gases with different  isotopic values  ( from -150 to -1000 per mil ) to calibrate a GC-IRMS .

Any suggestions ?

 

Thanks for your help
