To Check uECD Performance
1 Gather the following:
 Evaluation column, HP-5 30 m — 0.32 mm — 0.25 µm
(19091J-413)
 uECD performance evaluation (checkout) sample
(18713-60040, Japan: 5183-0379)
 4-mL solvent and waste bottles or equivalent for
autoinjector
 Chromatographic-grade isooctane
 2-mL sample vials or equivalent for sample
Verify the following:
 Clean fused silica indented mixing liner installed. If not,
install it.
 Chromatographic-grade gases plumbed and configured:
helium as carrier, nitrogen as makeup. (Nitrogen is an
acceptable alternate carrier gas.)
 Empty waste vials loaded in sample turret.
 4-mL vial with diffusion cap filled with hexane and inserted
in Solvent A injector position.
Install the evaluation column. (See the procedure for the SS or
PP in the Maintenance manual.)
 Bake out the evaluation column for at least 30 minutes at
