SS316, PTFE, Tefzel, glass, PEEK
Injection cycle time < 60 sec in all injection modes for 1 injection ≤ 100 µL
including 300 µL wash
Analytical performance
Injection modes Full loop, partial loop needle overfill, partial loop,
pressure-assisted sample aspiration
Reproducibility
(valid at 1.0 cP)
RSD ≤ 0.3% for full loop injections
RSD ≤ 0.5% for partial loop needle overfill injections,
injection volumes > 10 µL
RSD ≤ 1.0% for partial loop injections, injection
volumes > 10 µL
Carryover < 0.05% with programmable needle wash
Programming
Injection methods Full loop, partial loop needle overfill, and partial loop
Injection volume 0 µL - 10000 µL (with 1 µL increment), depending on
system settings
Maximum injection
volume
Full loop = loop volume
Partial loop needle overfill = ½ × of loop volume
Partial loop = (loop volume - [3 × needle volume])/2
Analysis time Maximum: 9 hr, 59 min, 59 sec
