8.3 Analytical characteristics
Injection modes
Full-Loop, Partial Loopfill, Pickup mode, PASA
™
(pressure-assisted sam-
ple aspiration)
Reproducibility
Relative standard deviation
≤
0.3% for the Full-Loop injection.
Relative standard deviation
≤
0.5% for the Partial Loopfill injection, injec-
tion volume > 10 µL.
Relative standard deviation
≤
1.0% for the Pickup injection, injection vol-
ume > 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
