Specifications

TYPE:

Programmable reciprocating pump, with single piston interchangeable head, constant strake and fast refill motion, internal pulse dampener, and pressure feedback.

WORKING RANGE

•     Flow rate: 0.025 - 5 mL/min.

•     Pressure: 0.1 - 60 MPa.

•     Temperature: 0 - 40°C for the module.

PUMP HEADS:

Any Gilson model working in the above range, specifically the 5SC for standard applications and the 10 WSC for salt-concentrated solutions (> 0.1M).

LIQUID CONTACT MATERIALS:

316L stainless steel, sapphire, ruby, PCTFE, PTFE;/HDPE.

PULSE DAMPENING

•     Pulsation: less than 1% with water at 1 mL/min and pressure higher than 8 MPa.

•     Dampener volume: 0.6 mL at atmospheric pressure, and 1.6 mL at 60 MPa.

FLOW RATE PRECISION AND ACCURACY AT 20°C OVER FULL WORKING RANGE

•     Coefficient of variation: 0.1 - 0.6% with aqueous solutions or hydro-organic polar solvent mixtures, and 0.3 -1% with hydrocarbons or chlorinated volatile solvents.

•     Maximum accuracy error ± 1% with water over the full flow rate and pressure ranges.

OPERATING MODES:

Constant flow rate (Flow), constant volume (Dispense), and time-based sequence (Program).

PROGRAM MODE AND SYSTEM CONTROL

•     Time: adjustable from 10 ^-2 to 10 ⁴ min, with increment from 0.01 to 1 min depending on the range used.

•     Program points: up to 25, induding flow rate and external events.

•     Flow rate: adjustable in mL/min, from 0.01% to 100% of the head maximum flow rate.

•     External events: 4 outputs contact closures to activate auto-sampler, integrator, fraction collector and detector autozero, and 1 input to wait for injection.

•     Up to 999 program loops and program Iinking.

•     Safety functions: 4 dedicated programs, for pressure outside of selected limits, input of an emergency signal (temperature threshold, leak detection, etc), and power failure.

MEMORY CAPACITY:

10 user's programs and 4 safety programs.

DISPENSE MODE:

Volume adjustable in mL from 10 ^-4 to 10 ² times the pump head size. For a 5mL head, from 0.5 µL to 500 mL. Dispense time or flow rate can be selected.

PUMP PARAMETERS:

Head number (5 or 10), liquid compressibility (0 to 999 Mbar ^-1 ), and refill time (125 to 1000 ms).

USER INTERFACE: 2 x 24 character LCD display. Front panel keypad. Built-in help messages. Information display for use and maintenance.

DIGITAL INTERFACE:

Gilson Serial Input Output Channel (GSIOC) slave connector on rear panel.

ELECTRICAL INTERFACE:

4 inputs and 4 relay outputs on rear panel.

SIZE:WxHxD:

33x15x33cm/13x6x13inches.
