Agilent 1100 HPLC System with Diode Array Detector (DAD) and Quaternary Pump

Insights by AMPTIUS | AMP Tech Instruments

Versatile Gradient HPLC for Routine and Advanced Analytical Laboratories

If your laboratory requires absolute confidence in peak identification and spectral purity without the premium price tag of brand-new instrumentation, the Agilent 1100 HPLC system equipped with a Diode Array Detector (DAD) and Quaternary Pump delivers the ultimate cost-effective solution. Driven by a robust quaternary pump operating at pressures up to 400 bar (5,880 psi), this system provides automated multi-solvent blending for up to four mobile phases, streamlining your method development while maintaining low-pulsation flow rates for excellent retention time reproducibility. The advanced Diode Array Detector offers full-spectrum UV-Vis acquisition spanning 190 to 950 nm, allowing you to capture complete absorbance spectra simultaneously and verify peak purity in a single analytical run. It is an industry-standard, rugged workhorse perfectly optimized for pharmaceutical impurity profiling, environmental contaminant screening, and food safety testing laboratories demanding regulatory compliance and rapid method development.

Agilent 1100 HPLC DAD Price and Cost of Ownership: Reliable Performance at Lower Cost

Certified refurbished systems typically range from approximately $12,000 to $19,000, providing substantial savings compared to comparable new platforms such as the Agilent 1260 Infinity II LC System with DAD and Quaternary Pump, which commonly range from approximately $45,000 to $65,000 or more depending on configuration, software, and automation options. Beyond the initial acquisition cost, laboratories should budget for ongoing operational expenses, including HPLC columns, solvents, mobile phase additives, degasser maintenance, pump seals, pistons, check valves, autosampler consumables, DAD lamp replacement, calibration standards, software support, preventive maintenance, and compliance-related qualification services. Long-term ownership costs remain manageable due to the proven durability of the Agilent 1100 platform, widespread availability of replacement parts, and extensive service support throughout the industry. Purchasing a certified refurbished Agilent 1100 HPLC System with DAD and Quaternary Pump allows laboratories to significantly reduce capital expenditures while maintaining access to reliable gradient performance, full-spectrum UV-Vis detection, peak purity analysis capabilities, and dependable chromatographic results for applications including pharmaceutical quality control, environmental monitoring, food analysis, chemical characterization, and regulatory compliance testing.

EPA Method 549.2: Determination of Diquat and Paraquat in Drinking Water Using the Agilent HPLC 1100 Series with DAD and Quaternary Pump

The Agilent 1100 HPLC System with a Diode Array Detector (DAD) and Quaternary Pump provides a highly effective platform for EPA Method 549.2, which is used for the determination of the herbicides diquat and paraquat in drinking water. The system's quaternary pump delivers precise solvent blending required for the ion-pair chromatography conditions specified by the method, typically utilizing ion-pairing reagents such as hexanesulfonic acid to retain these highly polar quaternary ammonium compounds on a reversed-phase C8 column and achieve reliable chromatographic separation. The DAD provides sensitive UV-Vis detection and full spectral acquisition capabilities, supporting accurate quantitation, peak purity evaluation, and additional confidence in analyte identification. Because diquat and paraquat readily adsorb to active silanol sites on untreated glass surfaces, laboratories benefit from using silanized glassware or compatible plastic materials such as PVC during sample preparation, storage, and autosampler operation, including the use of silanized or plastic sample vials to maximize analyte recovery and maintain method performance. Environmental and drinking water laboratories benefit from excellent retention time reproducibility, dependable quantitative accuracy, and robust long-term operation for regulatory monitoring programs. Combined with robust ion-pair chromatographic performance, comprehensive spectral detection, and proven Agilent reliability, the Agilent 1100 HPLC System with DAD and Quaternary Pump provides a powerful solution for EPA Method 549.2 herbicide analysis and drinking water compliance monitoring applications.
