Comments
Hydraulic system
Two dual piston in series pumps with
servo-controlled variable stroke drive,
power transmission by gears and ball
screws, floating pistons
Setable flow range
Set points 0.001 – 5 mL/min, in
0.001 mL/min increments
Flow range
0.05 – 5.0 mL/min
Flow precision
≤
0.07 % RSD or
≤
0.02 min SD, whatever is
greater
based on retention time at
constant room temperature
Flow accuracy
± 1 % or 10 µL/min, what ever is greater
pumping degassed H
2
O at
10 MPa (100 bar)
Pressure operating
range
Operating range 0 – 60 MPa (0 – 600 bar,
0 – 8700 psi) up to 5 mL/min
Pressure pulsation
< 2 % amplitude (typically < 1.3 %), or <
0.3 MPa (3 bar), whatever is greater, at
1 mL/min isopropanol, at all pressures >
1 MPa (10 bar, 147 psi)
Low delay volume configuration:
< 5 % amplitude (typically < 2 %)
Compressibility
compensation
Pre-defined, based on mobile phase
compressibility
