Comments
Hydraulic system
Two dual pistons in series pumps
with proprietary servo-controlled
variable stroke design and smooth
motion control.
Settable flow range
Setpoints 0.001 —2 ml/min, in
0.001 ml/min increments.
Executed in 300 pl/step
increments
Flow precision
≤
0.07 % RSD or 0.005 min SD,
whatever is greater
(0.2 —2.0 ml/min).
Based on retention time at
constant room temperature.
Flow accuracy
±1 % or 10 µl/min, whatever is
greater.
Pumping degassed H
2
O at
10 MPa (100 bar)
Pressure operating
range
Operating pressure range 120 MPa
(1200 bar), up to 2 ml/min.
Pressure pulsation
<1 % amplitude or < 0.5 MPa (5 bar),
whatever is greater.
At 1 ml/min water
Compressibility
compensation
Automatic, pre-defined, based on
mobile phase selection.
Gradient formation
High pressure binary mixing.
Delay volume
Jet Weaver V35: <45 µl
Jet Weaver V100: <75 µl
JetWeaver generally
recommended. For applications
requiring lowest delay volumes,
JetWeaver can be removed out of
the flow path. Delay volume is
then solely determined by the
volume of the connection
capillary.
Composition range
Settable range: 0 – 100 %
Recommended range: 1 — 99 %
or 5 µl/min per channel,
whatever is greater.
