Agilent 1290 Infinity I HPLC System w/ DAD

The Agilent 1290 Infinity I HPLC System with Diode-Array Detector (DAD) sets the standard for advanced liquid chromatography, offering unmatched precision, flexibility, and reliability. Designed to accommodate current and emerging column technologies, it ensures seamless method transfer from any HPLC or UHPLC system. With a wide flow rate range of 0.05 to 5 mL/min and a pressure capacity up to 1200 bar, it supports both conventional and ultra-high-performance chromatography. The advanced binary pump technology features heavy-duty motors, durable pistons for ultra-high pressure, and the innovative Jet Weaver mixing device, delivering ultra-low delay volumes and unparalleled flow stability. These features enable fast gradients, high resolution, and optimal compatibility with a variety of column diameters and mobile phase viscosities.

The system's variable volume autosampler is engineered for precision and efficiency, reducing carryover and ensuring accurate injections from 0.1 to 20 µL. Enhanced with advanced inert materials and automatic delay volume reduction (ADVR), it supports fast gradient delivery and reproducibility across the full injection range. The thermostatted column compartment further enhances performance, providing a temperature range from 10°C below ambient to 100°C with ±0.05°C stability. This compartment supports long and short columns, offers independent temperature zones, and ensures consistent results through a combination of pre-heating or cooling mobile phases, thermostat vanes, and still-air control.

The system’s DAD module leverages Max-Light cartridge cell technology with optofluidic waveguides to deliver high sensitivity, low dispersion, and a stable baseline. It features a wavelength range of 190 to 640 nm, a data collection rate of up to 160 Hz, and programmable optical slit adjustments for optimal spectral resolution and signal noise reduction. The Max-Light cartridge cells, available in standard 10 mm and optional 60 mm path lengths, are easily interchangeable and auto-aligned, ensuring consistent peak integration and sensitivity.

Additional system highlights include an integrated degasser for enhanced flow stability, a high-pressure binary gradient mixing capability, and solvent selection valves for flexible mobile phase management. The column compartment supports flow rates of up to 5 mL/min and accommodates three 30 cm columns, with rapid warm-up and cool-down times for increased efficiency. With its robust engineering, advanced features, and comprehensive operational range, the Agilent 1290 Infinity I HPLC System with DAD is the ultimate solution for laboratories requiring high-speed gradients, exceptional sensitivity, and reliable performance for demanding analytical applications.

The Agilent 1290 Infinity I HPLC System w/ DAD can be fully controlled from the Agilent ChemStation Version 4.3 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.
