Agilent is selling HP5 and DB5 columns but I cannot find the diffrence between them : the composition looks the same. Can you tell me the difference?
The Agilent GC columns portfolio is historically made up from the portfolios of 4 different companies acquired into Agilent.
As all had a 5% Phenyl/95% Methylpolysiloxane column we now have multiple columns with the same composition, but different names: DB-5 = HP-5 = CP-Sil 8 CB. The production processes and specifications might be different, but the compositions are not.
