889 IC Sample Center
8.3 Analytical characteristics
Injection modes Full-Loop, Partial Loopfill, Pickup mode, PASA ™ (pressure-assisted
sample aspiration)
Reproducibility Relative standard deviation ≤ 0.3% for the Full-Loop injection.
Relative standard deviation ≤ 0.5% for the Partial Loopfill injection,
injection volume > 10 µL.
Relative standard deviation
≤ 1.0% for the Pickup injection, injection
volume > 10 µL.
Memory effect < 0.05 % with programmable needle rinsing
8.4 Programming
Injection modes Full-Loop, Partial Loopfill, Pickup Mode
Injection volume 1…5000 µL (with 1 µL increment), depending on the system settings.
Max. injection vol-
ume ￭ Full Loop = Sample loop volume
￭ Partial Loopfill = 0.5 x Sample loop volume
￭ Pickup = (Sample loop volume - 3 x Needle volume)/2
