The Agilent 1290 Infinity Evaporative Light Scattering Detector is a high capability, instrument ideal for detecting analytes with no UV chromophore as it does not rely on optical absorption. The blue laser light source delivers excellent sensitivity whatever the compound to be analysed. The 1290 Infinity ELSD is the only ELSD that delivers sub-ambient operation for unrivalled detection of thermally labile analytes other ELSDs miss. The instrument delivers evaporation down to 10°C providing maximum sensitivity for compounds with significant volatility below 30° C. Real time gas control, Peltier cooling components and a range of other high quality equipment and enhancements provide excellent sensitivity, reproducibility and flexibility for many applications.

Features of 1290 Infinity Evaporative Light Scattering Detector
  • High sensitivity throughout each process is enabled by real-time control during injection, with programmable software. This sensitivity delivers superb responses for all compounds to low nanogram levels.     
  • Peltier-cooled evaporation tube cools to 10°C - 80°C preventing degradation of thermally labile compounds. Rapid heating and cooling of the evaporator tube minimizes equilibration time and increases sample throughput.     
  • Real-time gas control provides a uniform response across a solvent gradient that minimizes quantification errors.     
  • Control and data collection system is 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 that are ideal for Fast LC applications.     
  • Superb reproducibility below 2% for reliable and accurate results.     
  • Full DMSO transparency keeps early eluting compounds detectable.
