Agilent 1260 Infinity II LC System w/ VWD & RID

The Agilent 1260 Infinity II LC System w/ VWD & RID 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 the 1260 Infinity II Quaternary Pump is compatible with HPLC and UHPLC, i.e. handling 2.1, 3, and 4.6 mm ID columns over the flow rate range (up to 5 mL/min) and semi preparative analysis due to flow up to 10 mL/min. The 1260 Infinity II Multisampler can handle both vials and microtiter plates with ease and efficiency, and is designed for low carryover, as you can take clean to a whole new level with the multi-wash capability, cleaning all relevant injection parts between runs. This integrated feature flushes the injection needle outside with three solvents, and uses seat back flush procedures to reduce carryover to less than 9 ppm.

The Agilent 1260 Infinity II Variable Wavelength Detector (VWD) is the most sensitive and fastest detector in its class. The detector features time-programmable wavelength switching provides sensitivity and selectivity for your applications. More sample information can be acquired in the dual wavelength mode. Low detector noise (< ± 2.5 AU) and baseline drift (< 1 x 10^-4 AU/h) facilitates precise quantification of trace levels components. High productivity can be achieved with fast analysis at up to 120 Hz data rates. The Agilent 1260 Infinity II Refractive Index Detector (RID) is the ideal detector for fast and reliable LC results when routinely analyzing non-UV absorbing substances, such as carbohydrates, lipids, and polymers. The 1260 Infinity II RID is also the detector of choice for gel permeation chromatography (GPC) or size exclusion chromatography (SEC). Some of the features this RID detector includes are: high sensitivity and robust detection with an excellent reproducibility of only 0.1 % RSD, precise temperature control from ambient +5 °C to 55 °C to minimize baseline drift and optimize compound response, automatic light level adjustment compensates for lamp degradation and flow cell staining, ensuring optimum performance and lowest maintenance, and more. The Agilent 1260 Infinity II Multicolumn Thermostat (MCT) allows precise column thermostatting over a broad temperature range: from cooling down to 10 degrees below ambient temperature up to 85°C, providing high flexibility for optimized speed and selectivity of LC separation. For bio-inert applications bio-inert heat exchangers and a selection of bio-inert valves are offered by Agilent.

The Agilent 1260 Infinity II LC System w/ VWD & RID 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.
