  • Easy use of interfaceA simple, step-by-step method wizard guides you through detector setup
    Offers seven different languages for the user interface

  • Easy to maintainParts requiring cleaning or service are accessible from the front


  • Improves baseline stability and detection sensitivity compared to refractive index (RI)

  • Use ELSD in parallel with UV/Vis and MS for maximum structural and concentration information

  • Obtains a more accurate representation of sample mass than UV/Vis


  • Low noise and excellent baseline stability

  • Low nanogram detection limits
