It is well recognized that evaporative light scattering detectors (ELSD) can outperform traditional detectors when analysing non-chromophoric samples by HPLC, as the detection method does not rely on the optical properties of the analyte. ELSD detectors detect all compounds less volatile than the mobile phase, and with the advantage of low temperature operation, the benefits of ELSD compared to UV or RI now apply to an even wider range of HPLC applications.
Polymer Laboratories (PL), now a part of Varian, Inc., is a world leader in the design, build, service, and support of evaporative light scattering detectors, with almost 20 years' experience in this field. PL's ELSDs continue to lead the way in the development of the technology, with the performance of our instruments matched to customers' requirements.
PL Varian's three models of ELSD will deliver you high quality, high sensitivity, state of the art evaporative light scattering detection at an affordable price.
