Agilent 1260 Infinity I HPLC System w/ Quat Pump, DAD, & FLD

The Agilent 1260 Infinity I HPLC System w/ Quat Pump, DAD, & FLD offers the most flexibility for solvent selection and automation in HPLC method development, research and all HPLC applications requiring continuous access to a wide range of solvent choices. This system is ideally suited for multi-method, high-throughput workflows and offers convenient access to four solvents for isocratic or gradient analysis, for rapid method development and speeding up preparation of mobile phases and flushing the HPLC system.

The Agilent 1260 Infinity HPLC System's quaternary pump is based on a two-channel, dual-plunger in-series design which comprises all essential functions that a solvent delivery system has to fulfill. Metering of solvent and delivery to the high-pressure side are performed by one pump assembly which can generate pressure up to 600 bar. Degassing of the solvents is done in a built-in vacuum degasser integrated into the quaternary pump. The 1260 Infinity Autosampler is designed to offer the well-established flow-through design with variable volume injection and to achieve extremely low carryover, providing increased analysis speed with sensitivity, resolution, and precision. Paired with the autosampler is a thermostatted column compartment and ALS thermostat to serve as a temperature management system providing heating and cooling in order to meet extreme requirements of retention time reproducibility.

The featured Diode-Array Detector (DAD) is designed for the highest optical performance, GLP compliance, and easy maintenance. The DAD provides greatly enhanced sensitivity and baseline stability using a cartridge cell system with optofluidic waveguides. This detector provides for a wavelength range of 190 - 950 nm, a data acquisition rate of up to 80 Hz, and a programmable 1, 2, 4, 8, or 16 nm slit for rapid optimization of sensitivity, linearity, and spectral resolution. Also featured is the Fluorescence Detector (FLD), which brings high-sensitivity and selection through simultaneous multi-wavelength detection. This easy-to-use detector provides quantitative data and fluorescence spectra from a single run. Some of the features of the FLD Detector include; a flash lamp for highest intensity and lowest detection limit, multi-wavelength mode for on-line spectra, spectra acquisition and simultaneous multi-signal detection, easy front access to the flow cell for fast replacement, and built-in wavelength accuracy verification. Users may also use an optional cuvette for off-line measurements.

The Agilent 1260 Infinity I HPLC System w/ Quat Pump, DAD, & FLD can be fully controlled from the included Agilent ChemStation Workstation Software, which allows for user-friendly operation in data acquisition, analysis, instrument control, automation, and more.

This Agilent system is in excellent condition and will be fully tested to perform at factory specifications before being shipped.
