889 IC Sample Center
The syringe aspirates a rinsing volume of sample solution out of the
sample vial and fills the sample line with sample. The rinsing liquid is
expelled.
3 Switching the injection valve to LOAD
The injection valve is switched over to the LOAD position. This cau-
ses an homogenous sample plug to be present at the inlet to the
sample loop.
4 Filling the sample loop
The sample loop is quantitatively filled by a multiple of the loop vol-
ume being pumped through the loop.
￭ 3 × loop volume with sample loops ≤ 100 µL
