Specification

 

Eluent Selection

Four different mobile phase components; each can be proportioned from 0-100%

Pump

Dual-piston, variable speed, 100 µL (standard bore), 25 µL(microbore) stroke, user-selectable constant pressure or constant flow feedback control

Flow Rate

Standard bore pump head: 0.04 to 10.0 mL/min, linearly variable in increments of 0.01 mL/min

Microbore pump head: 0.01 to 2.50 mL/min, linearly variable in increments of 0.01 mL/min

Operating Pressure

35 MPa (5000 psi) maximum

Pressure Resolution

0.07 MPa (10 psi)

High Pressure Limit

0 to 35 MPa (0-5000 psi) in increments of 0.05 MPa (7.25 psi); trips instantaneously

Low Pressure Limit

0. to 35 MPa (0 to 5000 psi) in increments of

0.05 MPa (7.25 psi); trips after a time-out of 0.4 mL for thestandard bore GP40 or 0.1 mL for the microbore GP40

Delay Volume

Approximately 0.92 mL for standard bore pump heads or 0.72 mL for microbore pump heads, measured from the proportioning valve up to, and including, the 61-cm (24-in) pressure transducer outlet line

Channels

4-channel membrane vacuum degas

Materials

Wetted materials, PEEK, PTFE

Performance

>69% degas ratio @ 1 or 3 mL/min with 8.5 ppm O2 at input 0.200 Kg F/cm2 flow resistance @ 10 mL/min
