Agilent 1260 Infinity I HPLC System w/ Quat Pump, DAD, & FLD offers the most flexibility for solvent selection and automation in HPLC method development and research, as well as for all HPLC applications requiring continuous access to a wide range of solvents. 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 that provides all essential functions of a solvent delivery system. Metering of the solvent and delivery to the high-pressure side are performed by a single pump assembly capable of generating 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 achieve extremely low carryover, providing increased analysis speed with sensitivity, resolution, and precision. Paired with the autosampler are a thermostatted column compartment and an ALS thermostat, forming a temperature management system that provides heating and cooling to meet the extreme requirements for retention-time reproducibility.
The featured Diode-Array Detector (DAD) is designed for optimal optical performance, GLP compliance, and ease of maintenance. The DAD provides greatly enhanced sensitivity and baseline stability through a cartridge-cell system with optofluidic waveguides. This detector provides 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 the 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.
