Agilent 1260 Infinity II Evaporative Light Scattering Detector

The 1260 Infinity II Evaporative Light Scattering Detector (ELSD), although targeted at analytical scale, can also be used with a flow splitter for preparative chromatography applications. It is highly recommended for compounds with little or no UV chromophore, since the detector technique evaporates the solvent and then measures the intensity of the scattered light, which is directly proportional to the sample concentration.

There is no need to make any corrections for composition: the response is independent of any optical properties. Whatever temperature and gas flow rate is selected, the detector rapidly stabilizes and can be used within minutes. There is no baseline drift to consider, baseline integration is straightforward, and reproducibility is excellent. The detector can be programmed and controlled by many available LC software packages.

Features:

• High sensitivity for superb responses for all compounds down to low nanogram levels
• Real-time gas control for uniform response across a solvent gradient that minimizes quantification errors
• Control and data collection system - compatible with many vendor platforms
• Operation up to 120 °C gives improved evaporation of difficult solvents and better response to nonvolatile compounds
• Low dispersion and high-speed data output - ideal for fast LC applications
• Superb reproducibility below 2 % for reliable and accurate results
• Full DMSO transparency - no need for additional sample preparation when analyzing compound libraries, keeps early eluting compounds detectable
