SEDERE is the leading manufacturer of Low-Temperature Evaporative Light-Scattering Detectors (LT-ELSD) for HPLC, U-HPLC, HTLC, µ-HPLC, GPC, Preparative HPLC, Flash Chromatography, Counter Current Chromatography and SFC.These detectors range from entry-level unit to computer controlled systems for automated analyses thanks to several drivers.

Evaporative Light-Scattering Detectors provide a Universal detection mode for Liquid Chromatography and Supercritical Fluid Chromatography. It does not depend on the presence of chromophore groups on the compound and is therefore an extremely useful technique to get the complete picture of complex samples.

Typical applications include Carbohydrates, Lipids, Surfactants, Polymers but also Pharmaceutical High Throughput Screening and small molecules such as Amino Acids (without any derivation step) or Inorganic Ions (without the need of any additional post-column device). SEDERE LT-ELSDs are commonly used in Industrial, Governmental and University research and control laboratories.

As one of the originators of this detection mode, SEDERE remains exclusively focused on this technology as a core competency and has more than 25 years of experience in the development of versatile detection systems for all Chromatography Applications.The unparalleled selection of five LT-ELSD models can match both very high performance requirements and budget for all chromatography applications from basic research to quality control and purification.

SEDEX LT-ELSD Model 90LT

SEDEX Model 90 LT-ELSD combines total remote control with unrivalled sensitivities compared to all other highest performance aerosol-based detectors. This small and stackable unit occupies only 10 linear inches of bench space. Full SOP protocols are provided for GLP compliance and validation procedures. Sophisticated, yet easy to use, SEDEX 90LT is ready to detect with only two simple steps:

- Set one temperature
- Set gain

…then Detect!

This ELSD has been developed as well for ultrafast HPLC. 

The light source is a 405 nm laser, which increases the sensitivity even further.
Sedere’s unique Low-Temperature-Technology allows outstanding analytical results to be achieved with this detector.

As an universal detector, an ELSD offers numerous possibilities for detecting substances that have few or no chromophores (carbohydrates, proteins, peptides, polymers, lipids, steroids, etc.). Since the eluents are evaporated, the use of non-UV-compatible solvents poses no problems and the ELSD is gradient compatible. Complete SOP protocols for GLP conformity and validation procedures are available.

This detector can be controlled with OpenLab® EZChrom and ClarityChrom® software, via USB or RS-232 or via the keypad and digital display on the front panel, allowing it to be integrated into almost any LC system.

The Sedex 90 has the highest sensitivity of the ELSD Sedex family.

SEDEX LT-ELSD Model 85LT

SEDEX Model 85 LT-ELSD combines total remote control with excellent sensitivity. This small, stackable unit occupies only 10 linear inches of bench space. Full SOP protocols are provided for GLP compliance and validation procedures. Sophisticated, yet easy to use, SEDEX 85LT is ready to detect with only two simple steps:

- Set one temperature
- Set gain

…then Detect!

Evaporative Light Scattering Detection (ELSD) is a universal modern technology with which every analyte that is less volatile than the mobile phase can be detected.

Using the unique Low Temperature technology, this detector allows the achievement very high sensitivity.The technology is gradient compatible and is independent of the absorption characteristics of the eluents. Compounds can be universally measured with this detector (carbohydrates, proteins, peptides, polymers, lipids, steroids, etc.), regardless of their fluorescence, absorption or refractive-index characteristics. Comprehensive SOP protocols for GLP conformity and validation procedures are available.

This detector can be controlled with OpenLab® EZChrom and ClarityChrom® software, via RS-232 or via the keypad and digital display on the front
panel, allowing it to be integrated into almost any LC system.
