Web Information
Operating Specifications
- Number of eluents: Two
- Programmable flow rate range: 0.00 to 10.00 mL/min in 0.01 mL increments
- Flow precision: ≤ 0.1% RSD or 2 sec SD, six replicates, based on retention time or volumetric measures, at 1.0 mL/min, 1000 to 2000 psi back pressure, PQ test (each pump individually)
- Flow accuracy: ± 1.0% of setting at 1.0 mL/min or 30.0 μL/min, whichever is greater, using degassed methanol, 1000 to 2000 psi back pressure (each pump individually)
- Maximum operating pressure: 6000 psi (41,370 kPa, 401 bar)
- Operating pressure limits: Software programmable high and low pressure limits; user selectable in psi, kPa, bar
- Delay volume (1525): < 200 μL (with one GM 150 mixer)
- Gradient compositional accuracy (1525): ± 0.5% of setting at 1 mL/min and 1000 psi back pressure (methanol:methanol with propylparaben) with one GM 150 mixer
- Gradient compositional precision (1525): < 0.5% RSD of setting at 1.0 mL/min and 1000 psi back pressure (methanol:methanol with propylparaben) with one GM 150 mixer (based on six replicates of compositional accuracy)
- Pressure ripple (one pump): ≤ 2.0% at 1.0 mL/min, degassed methanol, at 1000 psi back pressure
- Gradient ripple: < 1.5% normalized to full scale between 10% to 90%, 1.0 mL/min, and 1000 psi back pressure (methanol:methanol with propylparaben with one GM 150 mixer)
