Polymethylmethacrylate (PMMA) standards are e x tremely versatile as they can be used for organic GPC with a wide range of medium polarity eluents, such as tetrahydrofuran, toluene, methyl ethyl ketone, and ethyl acetate. They also work well with more polar organic eluents, for e x ample dimethylformamide, dimethylacetamide, and he x afluoroisopropanol. The MWs are selected to provide equidistant calibration points for greater accuracy, covering from 500-1.5 million MW. Every kit contains 0.5 g...
