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)
