What you are buying
A refurbished Waters Acquity 2996 PDA detector. It records full UV-visible spectra for identification and peak purity, compatible across several Waters HPLC and UPLC platforms.
Every unit moves through the GenTech Certified process. Solution Scientists disassemble and inspect each module, replace all consumables and degraded wear components, then tune and calibrate the instrument and verify performance against OEM and published benchmarks using known reference chemicals. The instrument ships with its verification report. A certified-refurbished system gives you that performance without the capital cost or the lead time of a new purchase.
What Waters says about this platform
According to Waters Corporation, the 2996 Photodiode Array Detector operates as an integrated, versatile component within a chromatography system. It features advanced 512-photodiode array technology to offer exceptional optical resolution, outstanding sensitivity, and precise simultaneous 2D and 3D data acquisition. The module’s internal configuration allows independent optimization of data rates and filter time constants, making it an essential industry standard for compound identification, peak purity verification, and trace impurity quantitation down to 0.004%.
The detector is compatible across multiple Waters platforms, including Acquity UPLC systems, Alliance 2695 and 2795 HPLC systems, and the 1525 HPLC pump. Flow cell options include a standard 10-millimeter path length cell at 8 microliters, along with semi-preparative, microbore, and inert cell variants; the standard cell carries a 1,000 psi pressure limit. A prealigned deuterium lamp supplies the light source. Empower or MassLynx software controls acquisition.
What each module does
Photodiode array detection
Records a full UV-visible spectrum across 512 photodiodes as each compound elutes, supporting identification, peak purity checks, and co-elution detection.
The Waters ACQUITY 2996 PDA Detector Module acts as the optical sensory core of an analytical setup. It houses a prealigned deuterium lamp that projects light through the sample-filled analytical flow cell. A diffraction grating splits the exiting beam across 512 individual photodiodes. By reading the electrical discharge required to recharge each diode, the module seamlessly tracks light absorbance and converts it into comprehensive multi-wavelength spectral data.

What “GenTech Certified” means
Refurbishment at GenTech is a defined process, not a wipe-down. Every system moves through the same five stages.
1. Disassembly and rebuild. Solution Scientists strip the instrument down, clean each module inside and out, and rebuild it from the frame up. They replace pump seals, pistons, and check valves to specification.
2. Configuration and new parts. Solution Scientists install the options and modules you selected and fit new wear parts throughout. They replace the detector lamp with a new one and reset the lamp hours.
3. Diagnostic and performance testing. Solution Scientists tune and calibrate the instrument, run system diagnostics, and confirm detector wavelength accuracy. They test full-system pressure and gradient performance against OEM and published benchmarks using known reference chemicals.
4. Delivery and installation. The instrument ships in protective packing with a one-year warranty option and professional installation available from a GenTech Solution Scientist.
Labs that run this system
The Waters Acquity 2996 PDA Detector is method-compatible across the techniques most regulated and research labs run every day. These are the application areas buyers ask about most.
PFAS testing
EPA Method 537.1 and similar state programs require quantitation of per- and polyfluoroalkyl substances in drinking water at low parts-per-trillion levels, a sensitivity range triple quadrupole MS is built to reach.
Pesticides and mycotoxins
Multi-residue pesticide panels and mycotoxin screens in food and cannabis testing often cover more than 100 compounds in a single run, each requiring the selectivity a triple quadrupole provides against a complex matrix background.
Trace impurities and cleaning validation
Pharmaceutical cleaning validation protocols confirm that equipment surfaces carry no detectable residue of the previous product, often down to sub-part-per-billion swab or rinse limits.
Quantitative toxicology
Forensic and clinical toxicology panels quantify drugs and metabolites in blood, urine, or tissue against legally defensible limits, where a triple quadrupole’s selectivity rules out false positives from matrix interferences.
GLP-grade quantitation
Good Laboratory Practice studies require documented, audit-ready quantitation with full method validation, a standard regulated bioanalysis labs run routinely on triple quadrupole platforms.
