A
Flow accuracy
±0.5% of setting at 1 mL/min, or 30 µL/min, whichever
is larger, using degassed methanol at 1000 to 2000 psi
backpressure (each pump individually)
Gradient accuracy
< ±1.0% between 10 to 90%, 1 mL/min, and 1000 psi
backpressure (methanol: methanol with 5.6 mg/L
propylparaben > 05 AUFS @257 nm and one GM150
mixer)
Gradient precision
<0.5% RSD between 10 to 90%, 1 mL/min, and 1000
psi backpressure (methanol: methanol with 5.6 mg/L
propylparaben > 05 AUFS @257 nm and one GM150
mixer)
Gradient ripple
<1.5% normalized to full scale between 10 to 90%,
1 mL/min, and 1000 psi backpressure (methanol: meth-
anol with 5.6 mg/L propylparaben > 05 AUFS @257 nm
and one GM150 mixer)
Gradient delay volume
<60 µL (without mixer, no manual injector and no
column heater) < 500 µL (with one GM150 mixer, no
manual injector, and no column heater)
