Waters 600 Pump |
|
Number of eluents |
One to four. |
Modes of operation |
Gradient, isocratic, and flow programming |
Operating flow range |
0.00 to 45 mL/min (225 µL heads), in 0.01-mL increments. 0.00 to 20 mL/min (100 µL heads), in 0.01-mL increments. |
Composition range |
0 to 100% programmable in 1% increments for each of four reservoirs: A, B, C and D. Total composition must sum to 100%. |
Compositional accuracy |
Better than 1.0%, independent of pressure. |
Automatic eluent sparging |
Standard, helium gas, input gas pressure range 50 to 150 psi (3.5 to 10.5 kg/cm2 ). Helium flow rate range 0 to 100 mL/min, programmable in 1 mL/min increments. |
Pressure maxima |
6000 psi (420 kg/cm2 ) at 10 mL/min. 1000 psi (70 kg/cm2 ) at 45 mL/min. |
Programmable pressure limits |
Lower: 0 to 5950 psi (0 to 416.5 kg/cm2 ) Upper: 51 to 6000 psi (3.6 to 420 kg/cm2 ) |
Program storage |
Storage for 15 sets of tables (gradient, program event, and detector), with a maximum of 15 steps per table. Storage for a time-based multi-method program with up to 48 individual steps. EEPROM stores setup parameters and tables, and preserves memory indefinitely following power loss or extended shutdown. |
Gradient profiles |
Eleven gradient curves (including linear, Step [2], concave [4], and convex [4]). Up to 80 curve segments can be linked. |
Liquid crystal display (LCD) |
5-inch (12.7-cm) diagonal screen. Sixteen lines with 40 characters per line. 320 x 200 pixels. Displays current operating conditions. Allows operator to monitor complete gradient and timed-event tables on single screens. Reverse video cursor prompts operator through program setup. |
Keypad, function keys, and screen keys |
Dedicated keys provide direct access to all display screens. Cursor movement keys simplify programming, editing, and parameter entering. All keys are eluent-resistant. |
Programmable timed events |
You can program and store 15 timed events for each table. Switches S1 through S4 are located on the controller’s rear panel for timed output to external devices. The following processes may also be controlled by timed-events: • Audible alarm • Sparge rate • Column temperature • Proceed to initial conditions of specifed table • Start run of specified table • Turn detector lamp off |
