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)

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
(contribution of the pump to the system gradient delay 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
