Description
Model 3300 ELSD is designed for use with High Performance Liquid Chromatography (HPLC) systems to analyze any sample compound that has sufficiently lower volatility than the mobile phase. Some of its possible application areas include carbohydrates, pharmaceuticals, lipids, triglycerides, underivatized fatty and amino acids, polymers, surfactants, nutraceuticals, and combinatorial libraries. Evaporative light scattering detection eliminates common problems associated with other HPLC detectors. Refractive Index (RI) detectors can be complicated by solvent front interferences, baseline instability, and gradient incompatibility. RI detectors can also have a less sensitive response than ELSD. Low-wavelength UV can suffer baseline drift with steep gradients and also requires that the analyte contains a chromophore. ELSD does not have these limitations. It can achieve stable baselines with multisolvent gradients for improved resolution and faster separations. Also, since ELSD response does not depend on the sample»s optical characteristics, the sample does not require a chromophore or fluorophore for detection.
