Does GC capillary column(like a HP-1) has maximum operational inlet pressure?
I 'd like to use column at constant inlet pressure, 95psi.
GC S/SL inlet can supply upto 100psi(general GC).How about column? It also can maintain at that high pressure?
Actually I have plan to combine two columns(100mx0.25mmx0.5um and 2.5mx0.1mmx0.1um) for GCxGC.
When I use single column(100mx0.25mmx0.5um) the inlet pressure is 44psi constantly.
After combine, I have to set inlet pressure to 95psi for the same column flow with single column to compare data.
