ELSD-UM5000 evaporative light scattering detector

ELSD-UM5000 evaporative light scattering detector 

Introduction
Evaporative light scattering detector has been widely applied to the detection of carbohydrates , lipids , fatty acids , amino acids, drugs and polymers , in particular, is the active ingredient of traditional Chinese medicine and Chinese medicine -free violet absorption measurement . Evaporative Light-scattering Detector, referred ELSD,is a universal detector , detects the mobile phase is less volatile than any of the samples , the samples need not have a light-absorbing property . Can solve the detection problem of HPLC, if no derivatives of fatty acids and phospholipids, sugars, amino acids, etc., without pillar, column after derivative; Signal response associated with the sample quality, quality of the object to obtain the unknown information; A wide range of gradient and solvent compatibility, without solvent peak interference (solvent gradient can be obtained more stable baseline, without solvent peak interference, affected by the temperature small); Separation of complex samples, the liquid phase can be appropriately adding modifier, such as:, glacial acetic acid, formic acid, ammonium acetate TFA, ammonia, triethylamine, etc.
