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 For information about the chemical resistance of materials refer to the technical literature. |
Solvent and additive information | |
Safety features | Leak detection and safe leak handling, excess pressure monitoring |
Good Laboratory Practice (GLP) features | Predictive Performance functions for scheduling maintenance procedures based on the actual operating and usage conditions of the pump. All system parameters logged in the Chromeleon Audit Trail. |
