The ELSD-LTII is ideally suited for such applications as drug discovery, natural products development, combinatorial chemistry, and food and beverage.
ELSD-LTII
Evaporative Light Scattering Detector
Enhanced Sensitivity for Trace Analysis
The ELSD-LTII utilizes a high-efficiency LED and enhanced digital signal treatment to minimize noise and deliver optimum sensitivity for trace analysis. An innovative cell design also reduces band broadening and allows sensitivity levels below 200 picograms. The high-performance optical detection system can also be used for combinatorial chemistry and high-throughput screening applications. The new Low Temperature Evaporative Light Scattering Detector (ELSD-LTII) is an easy-to-operate, universal detector that identifies analytes with uniform sensitivity regardless of their spectroscopic properties. It is not a spectroscopic detector. Instead, it removes the mobile phase through evaporation and then makes a light scattering measurement of the dried analyte particles.

Simultaneous Analysis of 10 Saccharides and Sugar Alcohols in Beverages by Nexera LC-40 and ELSD
This video presents you the simultaneous analysis and separation of 10 saccharides and sugar alcohols in beverages by Shimadzu Nexera LC-40 and ELSD. Saccharides and sugar alcohols show very narrow UV absorption wavelength range, from 190 nm to 195 nm. Therefore, a refractive index detector (RID) is commonly used for this analysis. However, gradient elution cannot be used with RID because the baseline drifting derived from the change of mobile phase composition during gradient elution is unacceptable. So, RID is not suitable for a simultaneous separation of compounds that show widely different retention behaviours due to expected long analysis time without gradient elution. Evaporative light scattering detector (ELSD) is one of universal detector that detects the scattering light from the target compounds after nebulizing and evaporating the mobile phase. ELSD provides reduced analysis time and simultaneous separation of compounds that show widely different retention due to applicability to gradient elution. The performance of Nexera LC40 and ELSD was evaluated by intra-day and inter-day repeatability tests. Good intra and inter-day reproducibility results show the analysis method and systems are very stable.

Total BioPharma Workflow | Shimadzu
This video presents Shimadzu's solutions for Total Biopharma Workflow. Currently, the biopharma market is seeing the rise of exciting trends such as innovative biotherapeutics developed to treat illnesses including cancer and autoimmune diseases. However, these biomolecules are much more complex than small molecules and thus difficult to perform extensive analytical characterization.
