UNIEX-7700 Evaporative Light Scattering Detector (ELSD) is a universal detector newly launched by Unimicro Technologies of the United States .
Any sample with lower volatility than the mobile phase can be detected without the need for a chromophore. ELSD has higher sensitivity than refractive index detectors, is insensitive to temperature changes, and has a stable baseline. It is suitable for use with gradient elution liquid chromatography.
It has been widely used in the detection of carbohydrates, lipids, fatty acids, amino acids, drugs and polymers, especially in the determination of active ingredients of Chinese medicines and Chinese patent medicines without UV absorption .
