A new piece of equipment had been added to our repertoire, allowing us to calculate purity of compounds and quantification of unknown compounds - an evaporative light scattering detector Shimadzu ELSD-LTII.
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.
