Agilent 1260 Infinity HPLC System with Binary Pump and Variable Wavelength Detector (VWD)

What you are buying

Most assay, impurity, and trace-analysis methods in pharmaceutical, environmental, and food labs run on the liquid chromatography the Agilent 1260 Infinity delivers. The pump drives the mobile phase through the column at constant, reproducible flow; the sampler injects a precise volume; the column compartment holds temperature steady; the detector measures each compound as it elutes. GenTech rebuilds and tests the pump, sampler, thermostat, and detector, then verifies the stack as a system. You receive an HPLC that arrives ready to run your methods.

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 Agilent says about this platform

Agilent built the 1260 Infinity Binary and Quaternary LC systems to run at up to 600 bar and 0.05 to 5 mL/min, with injection volumes from 0.1 to 100 µL and columns to 300 mm long. The column compartment holds temperature from 10°C below ambient to 80°C, with higher maximums available. A flow-through sampler design and overlapped injection mode raise throughput. 384-well plate support processes up to 768 samples unattended. The quaternary system blends gradients of up to four solvents and integrates the degasser and its automatic purge valve into the pump module. Early Maintenance Feedback tracks module wear against configurable limits as a standard feature; optional extended GLP features add data security and traceability. Agilent designed the 1260 Infinity to accept a method built on a 1200 Series system without changing the column, mobile phase, pump settings, injection volume, column temperature, or detector settings.

What each module does

Pump

Delivers the mobile phase at constant flow and blends the gradient. Isocratic, binary, and quaternary configurations cover everything from single-solvent assays to four-solvent method scouting. Stable flow is the basis for the retention-time reproducibility every quantitative method depends on.

Sampler

Draws a precise volume from the vial or well plate and injects it onto the column. Automated sampling runs unattended sequences overnight.

Column compartment

Holds the column at a set temperature, which fixes selectivity and retention time. Temperature control turns a method written in one lab into the same method in another.

Detector

Measures each compound as it leaves the column. The diode-array detector records full UV-visible spectra for identification and purity; variable-wavelength, fluorescence, refractive-index, and evaporative light-scattering detectors cover the analytes UV cannot see.
