hi all,

i have an Agilnet GC 7890a TCD.

i was wondering how much sample injection is needed for the TCD detector to get a decent peak? 

for example, i dont get a good peak when i inject 5 microlitre of CO, but i get clear peaks for the injection volumes over 10.

my column is 2mm Shincarbon ST.

any comment or suggestions are appreciated.

Cheers

Hesam
