    Description

    Waters Acquity UPLC H-Class Quaternary Solvent Manager QSM P/N 186015018 is a high-pressure pump that can simultaneously pump four degassed solvents through the Acquity UPLC H-Class system. The pump can deliver gradients in eleven curve shapes (linear, two step, four convex, 4 concave).

    **This item has been tested for basic functionality. System will need to be validated/calibrated to ensure accurate results. Inquire if validation/calibration is available from seller for an additional cost. Unit has slight cosmetic blemishes from normal use. See photos for further details.

    Features:
    A gradient proportioning valve (GPV), to dynamically blend solvent sin any specified combination. The GPV produces predictable gradient segments regardless of solvent compressibility and system backpressure. Solvent selection and proportioning occur on the low-pressure (intake) side of the solvent delivery system, and solvents continue to blend under high pressure in each piston chamber.

    An integrated degasser that operates up to the maximum flow rate, with an independent channel for each solvent and an additional channel to accommodate the sample manager flow through needle (SM-FTN) purge solvent.

    An automatic, programmable, seal wash. The pumps wash plungers function prevents the build-up of precipitates on the pump plungers by washing them with seal wash solvent at user-specified intervals.

    An electronically controlled intelligent intake valve (i2Valve), to speed system priming and reduce startup times. Thei2Valve minimizes solvent flow disturbances in the inlet lines by closely synchronizing the valve performance with pump operation

    A vent valve that automatically switches to waste for priming and rapid solvent changeover.

    Component Description
    100-l mixer/filter
    Mixes and filters the solvent before it reaches the pump outlet.

    Accumulator pump
    Receives solvent from the primary pump and delivers it to the vent valve

    Check-valve
    A ball check-valve that allows flow in only one direction.

    Degasser vent tube
    Vents exhaust from the degasser pump

    Drain fitting (to waste)
    Connects the waste tubing to the leak management system.

    Drip tray
    Collects fluid leaks.

    Gradient proportioning valve (GPV)
    Blends solvents to create accurate gradients, regardless of solvent compressibility and system backpressure. The system includes two gradient proportioning valves, one for solvent channels A and B, and one for solvent channels C and D.

    i2Valve
    An electronically controlled ball check-valve that allows flow in only one direction

    Inlet manifold
    A component that combines the solvents upstream of pumps.

    Leak sensor
    Continuously monitors the quaternary solvent manager for leaks and stops the system flow when its optical sensor detects about 1.5 mL of accumulated, leaked liquid in its surrounding reservoir.

    Low pressure inlet filters (A, B, C, and D)
    A filter that removes particulates from incoming solvent

    Mobile phase degasser chambers
    Removes dissolved gasses from mobile phase solvents and exhausts them, and any condensates, through waste tubing

    Note: Vacuum degassing can change the composition of mixed solvents.

    Pressure transducer cable connectors
    The electrical connections for the pressure transducers located on the front of the actuators.

    Primary pump
    Draws solvent, transferring it to the accumulator pump and system as part of the serial flow design.

    Sample manager purge solvent degasser
    Degasses the sample manager pump solvent

    Note: Vacuuming degassing can change the composition of mixed solvents.

    Seal wash pump
    The pump that circulates solvent, to keep the actuators high pressure seals and plungers free of contaminants.

    Seal wash waste fitting
    Directs seal wash waste to the drip tray

    Solvent vent tubing
    Tubing that vents solvent to waste during priming.

    Optional solvent selection valve
    Select up to six different solvents for isocratic and gradient applications. When present, the valve is plumbed to solvent channel D, enabling selections D1 through D6.

    Vent valve
    A valve that automatically switches to waste during priming and a block position during the leak test
