摘要：
The performance of an evaporative light scattering detector in liquid chromatography of poly(ethylene glycol)s and their mono- and dimethyl ethers is evaluated. The aspect of quantitation is critically examined for isocratic and gradient elution. Molar mass dependence of response factors for the different homologous series is studied at different evaporator temperatures, and compared to those from isocratic elution with density and refractive index detection.
