Leak detector Integrated into the drip tray.
Pump synchronization Pump cycle synchronizes with the SM-FL injection cycle to
enhance retention time reproducibility.
Solvent conditioning (co-solvent
pump only)
Integrated vacuum degassing, four chambers.
Gradient formation High pressure mixing, binary gradient.
Gradient profiles 11 gradient curves, including linear, step (2), concave (4),
and convex (4).
Mixing options Standard: 250 μL
Primary check valves • Active inlet check valve on the co-solvent primary pump
uses Intelligent Intake Valves (i
2
Valve)
• Passive check valve used on the A side of the primary
pump
Vent valve Automated vent valve allows for priming the pump and
testing for leaks.
Solvent lines Factory-installed tubing assemblies. The stainless steel
CO

inlet tubing connects to the ccManager.
Each co-solvent inlet tubing assembly includes a 10 µm
reservoir filter, and a colored-coded permanent label near
the end of each tube.
pH range 2.0 to 12.0
Compressibility compensation Automatic and continuous.
Solvent and seal wash containers The side-mounted solvent tray can hold as many as six
solvent reservoirs.
Seal wash pump Equipped with a programmable active wash system, to
flush the rear of the high pressure seals and plungers.

cooling Temperature at the primary pump set point is 2 ºC, −1 ºC +3
ºC.
Temperature at the accumulator head set point is 13 ºC, ± 2
ºC.
By default, cooling is always operative.
Operating pressure range 0 to 6,000 psi for flow rates of 3.25 mL/min and lower.
At flow rates above 3.25 mL/min, a progressive linear
decrease to 4,250 psi at 4 mL/min occurs.
Settable flow rate range 0.010 mL/min to 4.0 mL/min in 0.001 mL/min increments.
Usable system flow range is 0.5 to 4.0 mL/min and is
determined in conjunction with the ABPR.
Pump delay volume <275 μL with a standard 250-μL mixer.
Flow precision 0.075% RSD or ± 0.02 min standard deviation, whichever is
greater, based on six replicates.
