Waters Alliance e2695 HPLC System with Waters 2475 Fluorescence Detector

Insights by AMPTIUS | AMP Tech Instruments

High-Sensitivity Fluorescence Detection for Trace-Level Chromatographic Analysis

If your laboratory needs to achieve ultra-low detection limits and eliminate matrix background interference for naturally fluorescent or derivatized target compounds, the Waters Alliance e2695 HPLC System with 2475 Multi-Wavelength Fluorescence Detector provides an industry-leading analytical solution. Driven by the smooth, low-pulsation quaternary solvent delivery and precise sample handling of the e2695 separations module, this system ensures rock-solid retention time reproducibility across large sequence queues. The integrated Waters 2475 fluorescence detector features an advanced optical path covering excitation 200–890 nm and emission 210–900 nm, enabling high-speed, multi-wavelength switching within a single injection sequence to quantify target analytes at trace levels. Outperforming traditional UV detectors when working with complex matrices, this system serves as an indispensable tool for food safety labs tracking aflatoxins and mycotoxins, environmental facilities measuring the fluorescence-responsive portion of the PAH panel, and pharmaceutical QA/QC operations running API impurity profiles, vitamin assays, and biomolecule characterization sequences.

Waters e2695 Price and Cost of Ownership: Reliable Performance at Lower Cost

The Waters Alliance e2695 HPLC System with Waters 2475 Fluorescence Detector provides a reliable and cost-effective chromatography solution for laboratories requiring highly sensitive fluorescence detection in pharmaceutical, environmental, food safety, biotechnology, and research applications. New systems typically range from approximately $55,000 to $75,000, depending on detector configuration, software packages, and autosampler options, while certified refurbished systems generally range from $12,000 to $18,000, offering substantial savings on initial capital investment. In addition to acquisition costs, laboratories should consider ongoing operational expenses such as HPLC solvents, mobile phase additives, analytical columns, fluorescence lamp replacements, tubing, seals, injector maintenance, autosampler consumables, calibration standards, preventive maintenance, software licensing, and compliance-related qualification support for USP, FDA, AOAC, ISO, and cGMP workflows. Long-term ownership considerations may also include detector servicing, pump maintenance, replacement electronic components, and optional service contracts to maintain stable chromatographic performance and reliable fluorescence sensitivity in high-throughput laboratory environments. Purchasing a certified refurbished Waters Alliance e2695 HPLC System with Waters 2475 FLR Detector allows laboratories to significantly reduce ownership costs while still benefiting from dependable chromatographic separation, sensitive fluorescence detection, and proven long-term analytical performance for regulated and research-based laboratory applications.

EPA Method 531.2 Analysis with Waters Alliance e2695 HPLC with Waters 2475 FLR Detector

The Waters Alliance e2695 HPLC System, integrated with the 2475 Fluorescence (FLR) Detector, is a premier platform for analytical workflows aligned with EPA Method 531.2. Specifically designed for the determination of N-methylcarbamoyloximes and N-methylcarbamates in drinking water, this configuration provides the high-precision solvent delivery and stable gradient elution required for the separation of polar pesticides in complex matrices. The system's primary advantage lies in its compatibility with post-column derivatization instrumentation; the e2695's pulse-free flow supports the consistent chemical 'tagging' step required to make these analytes fluoresce. This configuration does not include a post-column derivatization module, which must be added separately to achieve full EPA Method 531.2 compliance. Once paired with a compatible derivatization unit, the 2475 FLR detector provides the sensitivity and selectivity needed to monitor specific excitation and emission wavelengths, effectively eliminating background interference and achieving the sub-part-per-billion detection limits mandated by the EPA. When validated according to laboratory SOPs, this Waters Alliance configuration offers a rugged, automated, and highly reliable solution for the rigorous demands of regulatory carbamate analysis.
