Restek 10047 10mx.53mm Intermediate-Polarity Deactivated Guard/Retention Gap Columns/Transfer Lines (fused silica)
Has anyone used this guard column or have other suggestions that might work better?
Restek Cat.# 10084 10mx.53mm
Hydroguard Water-Resistant Guard/Retention Gap Columns/Transfer Lines (fused silica)
We are measuring anywhere from .5 to 1000 ug/mL and sometimes to MDL ~.05 ug/mL so are trying to improve our chromatography and reporting limits.
Agilent 6890 FID, splitless mostly and split @5:1,..we have several different methods depending on the analytes and concentrations, and yes I know the liner is not supposed to work with 2ul water but it does...
Thanks
