Waters Alliance 2695 HPLC System with 2475 FLR Detector: Applications in Pharma, Food, and Environmental Labs

The Waters Alliance 2695 HPLC System with Waters 2475 Fluorescence Detector is widely used for high-sensitivity chromatographic analysis in pharmaceutical, environmental, food safety, chemical, biotechnology, and academic laboratories. Common laboratory applications include pharmaceutical assay testing, impurity profiling, dissolution studies, stability-indicating methods, and trace-level compound quantitation in workflows aligned with USP, FDA, and cGMP analytical requirements. Environmental laboratories commonly utilize this configuration for polynuclear aromatic hydrocarbon (PAH) analysis following EPA Method 8310, pesticide and herbicide testing, and contaminant monitoring in water and soil samples. In food safety laboratories, the system supports mycotoxin analysis, vitamin quantitation, preservative testing, and food additive analysis following AOAC analytical frameworks. Biotechnology and research laboratories frequently apply the system for amino acid analysis, biomolecule characterization, metabolite profiling, and fluorescence-based compound detection workflows. The Waters 2475 Fluorescence Detector provides highly sensitive and selective fluorescence detection for naturally fluorescent or derivatized compounds, while the Waters Alliance 2695 platform delivers reliable solvent delivery, stable retention times, low carryover, and dependable chromatographic reproducibility for routine and high-throughput laboratory applications.

Waters Alliance 2695 HPLC System with 2475 FLR Detector: Refurbished System Benefits and Pricing

The Waters Alliance 2695 HPLC System with Waters 2475 Fluorescence Detector provides a dependable and cost-effective chromatography solution for pharmaceutical, environmental, food safety, chemical, and research laboratories requiring sensitive fluorescence detection capabilities. Certified refurbished systems typically range from approximately $8,500 to $16,500, offering substantial savings compared to newer comparable platforms such as the Waters Alliance iDS HPLC System paired with the Waters 2475 Fluorescence Detector, which commonly range from $65,000 to over $88,000 depending on system configuration and software options. In addition to the initial acquisition cost, laboratories should consider ongoing operational expenses such as HPLC solvents, mobile phase additives, fluorescence lamp replacements, analytical columns, tubing, seals, injector maintenance, autosampler consumables, calibration standards, preventive maintenance, software licensing, and compliance-related qualification support for USP, FDA, EPA, ISO, AOAC, and cGMP workflows. Long-term ownership considerations may also include detector maintenance, pump servicing, replacement electronic components, and optional service contracts to maintain stable chromatographic performance and sensitive fluorescence detection in high-throughput laboratory environments. Purchasing a certified refurbished Waters Alliance 2695 HPLC System with Waters 2475 Fluorescence Detector allows laboratories to significantly reduce capital expenditures while still achieving reliable chromatographic separation, dependable fluorescence sensitivity, and proven long-term analytical performance for regulated and research-based laboratory applications.

EPA Method 610: PAH Analysis using Waters Alliance 2695 and 2475 FLR

The Waters Alliance 2695 HPLC System, integrated with the Waters 2475 Fluorescence (FLR) Detector, is a premier platform for analytical workflows aligned with EPA Method 610. Specifically designed for the determination of polynuclear aromatic hydrocarbons (PAHs) in municipal and industrial discharges, this configuration provides the high-precision quaternary solvent delivery and stable gradient elution required to resolve complex mixtures of these semi-volatile organic compounds. The system’s primary advantage lies in the 2475 FLR detector’s ability to utilize time-programmed excitation and emission wavelengths, allowing for the selective and high-sensitivity detection of individual PAHs at trace levels while effectively eliminating non-fluorescent background interference. When validated according to laboratory SOPs, this Waters Alliance configuration offers a rugged, automated, and highly reliable solution for the rigorous demands of environmental monitoring and regulatory PAH analysis.
