The pump performance is specified as follows:
Type | Specification |
---|---|
Operating principle | Serial dual-piston pump with independent piston drives |
Compressibility compensation | Fully automated, independent of the composition of the mobile phase |
Flow range (settable) | 1 nL/min – 100 µL/min in 1 nL/min increments |
Flow accuracy | Typically: ± 3% Conditions: 0.1 - 100 µL/min any of 4 pre-calibrated solvents, measured at 20 MPa system pressure |
Inter-module deviation | < 5% for flow rates > 300 nL/min – 10 µL/min Conditions: Measured by retention time differences of TGQAPGFSYTDANK Cytochrome C protein digest peptide and 30 min gradient. |
Retention time precision | ≤ 0.2% RSD or ≤ 0.1 SD min, whichever is greater Conditions: For TGQAPGFSYTDANK Cytochrome C protein digest peptide for gradients 30 – 90 min. |
Pressure range | Pump pressure: 2 – 150 MPa (20 – 1500 bar, 300 – 21750 psi) 150 MPa pump pressure up to 1 µL/min. With a flow rate above 1 µL/min, the maximum pressure is solvent dependent and decreases linearly down to 70 MPa at 100 µL/min for acetonitrile 80% in channel B. |
Number of solvent channels | 2 |
Maximum stroke volume | 96 µL |
Dwell volume | 25 nL |
Degassing | 2 channels for autosampler wash liquids |
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 and one relay output System Interlink: 2 System Interlink ports (RJ45-8 connectors) |
Materials in the analytical flow path | Ceramics, DLC (diamond like carbon), fluoropolymers, MP35N, PEEK, titanium, UHMW PE For information on the chemical resistance of materials, refer to the technical literature. |
