Polymer Labs PL-ELS 2100 HPLC Evaporative Light Scattering Device

Cambridge ID #: 10920

The Polymer Laboratories PL-ELS 2100 Evaporative Light Scattering Detector outperforms traditional HPLC detectors when analyzing non-chromophoric components in a sample. ELS detection does not rely on the optical properties of the analyte. Thus, for a semi-volatile and non-volatile compounds, you achieve a signal that is proportional to concentration – a truly universal detector.

Features:

  • Compatibility with a wide range of solvents
  • Ideal complement to LC/MS, universal detector
  • Completely gradient compatible (unlike RI detection)
  • No analyate chromaphore required (unlike UV-vis)
  • ELS detects anything that is less volatile than the mobile phase ( like, sugar, Phospholipid, etc)
  • Eliminates the need for derivatization steps for selected analyates ( such as amino acid)
  • Fast setup and equilibration
  • Sensitivity in the range of 1-50ng on the column
  • No interference from solvent front peaks
  • Flow rates up to 5 mL/min can be achieved with no effect on baseline.
  • Ideal for high throughput screening
  • Low temperature operation even in 100% water
  • Small footprint with ergonomic design
  • Easy to use
