1290 Infinity II Evaporative Light Scattering Detector
Sensitive, reproducible evaporative light scattering detection over a wider dynamic range
The Agilent 1290 Infinity II Evaporative Light Scattering Detector (ELSD) 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 analyzed. The 1290 Infinity II 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. The extended dynamic range PMT technology gives four orders of magnitude detection for trace impurity analysis. 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.
-
High sensitivity throughput - 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 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 - 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 - ideal for fast LC applications.
-
Superb reproducibility below 2% - for reliable and accurate results.
-
Full DMSO transparency - keeps early eluting compounds detectable
