Answer:It proportions up to four mobile-phase solvents for reproducible gradient mixing.
Answer:Waters Alliance separation modules, including 2695, 2695D, and 2795.
Answer:No. It is a gradient proportioning valve assembly used within a compatible HPLC system.
This Waters gradient proportioning valve assembly is a replacement solvent-selection component for compatible Alliance HPLC separation modules. The valve meters up to four mobile-phase solvent channels by precisely timing solenoid-driven inlet openings, supporting accurate and reproducible gradient mixing. Applications include servicing Alliance 2690-era systems and compatible 2695, 2695D, or 2795 separation modules where solvent proportioning problems have been diagnosed. Correct GPV operation is important for gradient accuracy, chromatographic retention-time reproducibility, and stable method performance. The assembly is a fluidic service part, not an autosampler injection valve, complete pump, or entire HPLC module. The correct replacement should be matched against the instrument model and service documentation, especially where earlier configurations and revision-specific parts may be present.
