Delivers precise gradients and stable flow through a reciprocating tandem-plunger design, pressure-dynamic suppression algorithm, hardened alloy-steel cam, high-power motor, self-lubricating gearing, and a suspended floating plunger with automatic rinse and purge functions. A four-channel solvent-selection valve and independent gradient proportioning valves simplify solvent switching and maintenance.

Provides accurate, low-carryover injections via a constant-pressure sampling needle and ultra-precision pump. Features pre-loaded sample injection for 5-second cycles, multiple injection modes, optional temperature control and dehumidification, and front-access injection valve for easy upkeep.

Maintains constant, uniform column temperature with fuzzy-PID control, ban-based air circulation, and multi-layer insulation. Triple protection—real-time leak detection, Peltier and cavity monitoring, and over-temperature shut-off—ensures safe operation.

UV-Vis Detector: patented static light path and transmission-type deuterium lamp for reliable, low-LOD measurements without lamp movement.

Diode-Array Detector: captures full-spectrum data for peak purity and spectral similarity checks.

Optional modules (FLD, RID, ELSD, CAD) extend detection to diverse compounds.
