High-Sensitivity Fluorescence Detection for Trace-Level Chromatographic Analysis

The Waters Alliance e2695 HPLC System with the Waters 2475 Multi-λ Fluorescence Detector is a high-performance liquid chromatography platform engineered for the precise qualitative and quantitative analysis of naturally fluorescent and derivatized compounds. Combining the integrated solvent and sample management capabilities of the Alliance e2695 Separations Module with the 2475 Fluorescence Detector, the system features programmable excitation and emission wavelengths from 200 to 890 nm, rapid wavelength switching, and high-sensitivity fluorescence detection for exceptional selectivity and ultra-low detection limits. The detector supports multi-wavelength acquisition within a single analytical run, enabling accurate compound identification and quantitation while minimizing interference from complex sample matrices. Environmental laboratories utilize this platform for polycyclic aromatic hydrocarbon (PAH) and pesticide analysis. Food and beverage laboratories rely on the system for aflatoxin, vitamin, amino acid, and food additive testing; biotechnology laboratories analyze proteins, peptides, and biomolecules, and chemical laboratories support trace-level quality control and method development. Combining dependable chromatographic performance, advanced fluorescence sensitivity, and proven Waters reliability, the Alliance e2695 HPLC System with the 2475 Fluorescence Detector provides a robust, cost-effective solution for routine QA/QC testing, regulatory compliance, and demanding trace-level analytical workflows.

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 seamless compatibility with post-column derivatization, where the e2695’s pulse-free flow ensures the consistent chemical "tagging" necessary to make these analytes fluoresce. The 2475 FLR detector then provides the superior 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.
