  • About ELSD

         Evaporation light scatting detector (ELSD) is a kind of universal detector, which can detect any sample with lower volatility than the mobile phase. ELSD has a stable baseline and is much more sensitive than RI. Besides, ELSD is not sensitive to temperature changes and can be coupled to gradient HPLC without baseline drift.

         ELSD has been widely used to detect the carbohydrate, lipoid, fatty acid, amino acid, medicine and polymer, specially to detect those active traditional Chinese medicine ingredients without UV absorption.
