Agilent 1290 Infinity II Evaporative Light Scattering Detector by Agilent Technologies

The 1290 Infinity II Evaporative Light Scattering Detector (ELSD) is ideal for reproducible, sensitve detection of both volatile and nonvolatile compounds that cannot be detected by UV. A unique peltier cooled evaporator coupled with an original gas flow design allow subambient operation down to 10 °C. This delivers maximum sensitivity for compounds with significant volatility below 30 °C.

Novel PMT technology enables an extended dynamic range of four orders of magnitude for trace impurity analysis. This unique design provides excellent sensitivity, reproducibility, and flexibility for a multitude of applications.

Features:

• High-sensitivity throughput - each process is enabled by real-time control during injection, with programmable software. This sensitivity delivers superb responses for all compounds down to low nanogram levels
• Peltier-cooled evaporation tube - cools to 10 to 80 °C, preventing degradation of thermally labile compounds
• Rapid heating and cooling of the evaporator tube - minimizes equilibration time and increases sample throughput
• Extended dynamic range detection technology gives four orders of magnitude, enabling analysis of samples with trace levels of impurities in a highly concentrated sample matrix, eliminating time-consuming reanalysis, recalibration, or sample preparation
• Real-time gas control - provides a uniform response across a solvent gradient that minimizes quantification errors
• Control and data collection system - compatible with many vendor platforms
• Solvent enhancement effects during gradient elution are eliminated through real-time evaporator gas programming for excellent quantification
• Low dispersion and high-speed data output rates - ideal for fast LC applications
• Superb reproducibility below 2% for reliable and accurate results
• Full DMSO transparency - keeps early eluting compounds detectable
