Operating Specifications

  • Programmable flow rate:  0.00 to 5.00 mL/min, in 0.01 mL/min increments
  • Flow precision:  2 sec SD, six replicates based on retention time or volumetric measures at 0.2 mL/min,  1000 to 2000 psi back pressure, PQ test (each pump individually)
  • Flow accuracy: 2.0% of setting at 0.1 mL/min using degassed methanol at 1000 to 2000 psi backpressure  (each pump individually)
  • Maximum operating pressure:  6000 psi (41,370 kPa, 401 bars)
  • Operating pressure limits:  Software programmable high and low pressure limits; user selectable in psi, kPa, bar
  • Delay: volume  < 30 μL (without mixer), < 100 μL (with one 50 μL mixer)
  • Gradient accuracy:  < 1.0% of setting (typical) at 0.1 mL/min between 10% to 90%, and 1000 psi backpressure (methanol:methanol with propylparaben and one 50.0 μL mixer)
  • Gradient precision:  < 0.5% RSD (typical) between 10.0% to 90.0%, 0.1 mL/min, and 1000 psi back pressure (methanol:water with octanophenone and one 50.0 μL mixer)
  • Pressure ripple (one pump):  < 2.0% at 0.5 mL/min, degassed methanol, at 1000 to 2000 psi back pressure
  • Gradient ripple:  < 1.5% normalized to full scale between 10.0% to 90.0%, 0.1 mL/min, and 1000 psi backpressure (methanol:methanol with propylparaben) with one 50.0 μL mixer
