3000 psi (20,685 kPa, 200.5 bars) for 225-µL heads;
programmable upper and lower limits
Pressure ripple
(one pump)
≤2.0% at 1 mL/min, degassed methanol, at 1000 psi
backpressure
Flow precision ±0.1% RSD of retention time at 1 mL/min, 1000 to
2000 psi, paraben PQ test, or 2 seconds SD
Flow accuracy ±1.0% of setting at 1 mL/min, or 30 µL/min,
whichever is larger, using degassed methanol at 1000
to 2000 psi backpressure
Instrument control and communication specifications
Item Specification
Operating pressure
output
Sends a 0 to –10 V analog output to an external
control device
Pressure limit
shutdown output
Sends a positive or negative voltage signal to an
external control device:
• +15 V signal = pressure limit shutdown
• –12.52 to –14.07 V signal = pressure within limits
External control
device input
TTL-level pulse stream from an external control
device
