Application of Evaporative Light Scattering Detector ELSD-LT (Part 3)Analysis of Surfactants

Introduction

The evaporative light scattering detector ELSD-LT can detect any compound except for volatile compounds. The ELSD-LT, applicable of gradient elution, is also effective for analyzing substances that could be only analyzed by the isocratic method using refractive index detectors due to the lack of UV absorption. Applications of the ELSD-LT have already been introduced in Application News L290 (triglycerides) and L294 (oligosaccharides). This Application News reports its applications for analyzing anionic and nonionic surfactants.
