Operating Manual
11.1.3 Isocratic Pump
The pump performance is specified as follows:
Type Specification*
Operating principle Serial dual-piston pump
Compressibility compensation Fully automated, independent of the composition of the mobile phase
Flow range (settable) 0.001 – 10 mL/min in 1 µL/min increments
Flow accuracy ± 0.1%
Flow precision < 0.05% RSD or < 0.01 min SD, whichever is greater
Pressure range 2-70 MPa (20-700 bar, 290 – 10100 psi)
With a flow rate of > 5 mL/min, the maximum pressure decreases
linearly down to 30 MPa (300 bar, 4350 psi).
Pulsation < 1.0% or < 0.2 MPa, whichever is greater
Number of solvents 1
Maximum stroke volume 80 µL
Mixer volume With the isocratic pump, the mixing system serves as inline filter.
Standard configuration: 200 µL mixing system, consisting of a capillary
mixer (volume: 50 µL) and a static mixer (volume: 150 µL)
Other mixing systems (inline filters) are available as an option.
Solvent degassing No (available as optional accessory)
Biocompatible No
Communication USB:
1 USB port (USB 2.0, "B" type connector)
1 USB hub with 3 ports (USB 2.0, "A" type connectors)
I/O Interface :
2 Dig I/O ports (mini-DIN), each providing one input, one relay output,
and one bidirectional input/output
System Interlink :
2 system interlink ports (RJ45-8 connectors)
Control Chromeleon 7
The pump can be operated also with other data systems. For details,
contact the Thermo Fisher Scientific sales organization.
Keypad with 5 buttons for performing certain functions directly from
the pump
Materials in the analytical flow path Stainless steel, titanium, ceramics, sapphire, PEEK, UHMW PE,
fluoropolymers
