Agilent 1260 Infinity II LC System w/ Vialsampler & DAD

The Agilent 1260 Infinity II LC System w/ Vialsampler & DAD provides a liquid chromatograph offering ultra fast and high resolution separation capability for consistently accurate results. The 1260 Infinity II LC System delivers several ease-of-use features, making it a standard system for routine analysis. With an operating pressure of up to 600 bar and flow range from 0.001 to 5.0 ml/min, the 1260 Infinity II Binary Pump is suited for LC applications using conventional or superficially porous particle columns, as well as STM column technology. Gradient formation is based on a high-pressure mixing principle. Standard or low delay volumes can be easily configured by the user. The Agilent 1260 Infinity II Binary Pump offers reproducible gradients and high-performance, providing high-throughput and fast separations. The pump is suitable for routine applications, with UV or MS detection, where high speed and resolution with uncompromised data quality are required. A two-channel integrated degasser is located inside of the pump, which allows for a volume of 0.45ml per channel.

The Agilent 1260 Infinity II Vialsampler is an autosampler designed for the reliability and ease-of-use needed for routine pharmaceutical tasks and quality control, as well as for environmental and food analyses. It houses an integrated column oven for two LC columns up to 30 mm in length. The integrated column oven paired with a sample cooler allows for temperature control from 4°C to 80°C, all within one module. Two classic trays are included with the Vialsampler, which allows for a capacity of up to 100 x 2 mL vials. The Vialsampler allows for an injection range of 0.1 to 900 µl up to a pressure of 40 MPa.

The Agilent 1290 Infinity II Diode Array Detector (DAD) is based on the Agilent Max-Light cartridge cell with optofluidic waveguides that improve light transmission to near 100% efficiency without sacrificing resolution caused by cell dispersions effects. With typical detector noise levels of ± 0.6 x 10^-6 AU the 60 mm flow cell gives up to 10 times higher sensitivity than detectors with conventional flow cells. Any compromising refractive index and thermal effects are almost eliminated entirely, resulting in significantly less baseline drift for more reliable and precise peak integration. For fast separations, this detector has multiple wavelength and full spectral detection at sampling rates up to 240 Hz. The long-life deuterium lamp allows for the highest intensity and lowest detection limits over a wavelength range of 190 to 640 nm.

The Agilent 1260 Infinity II LC System w/ Vialsampler & DAD can be fully controlled from the Agilent OpenLab CDS 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.
