Product name:

Evaporative light scattering detector

Product model: ELSD-500 Product time: 2021-07-06
Elsd500 adopts advanced optical design, which greatly provides sensitivity. Enhanced digital signal processing reduces peak width. Gain and temperature control, optimize the experimental method.

Product overview

Elsd-500 evaporative light scattering detector is the first evaporative light scattering detector product launched by Xuyu technologyElsd-500 can be widely used in the detection of carbohydrates, lipids, fatty acids, amino acids, drugs and polymers especially in the determination of effective components of traditional Chinese medicine and Chinese patent medicine without UV absorption
