For environmental sample clean-up according to EPA methods, Polymer Laboratories has launched PL EnviroPrep high resolution GPC columns
PL EnviroPrep columns permit a simple one stage clean-up procedure for the determination of pesticides in a variety of organic matrices, eg soil and animal tissue, etc The matrix is extracted and the higher molecular weight fractions such as lipids, polymers, natural resins and dispersed high molecular weight components are easily eliminated in the GPC analysis.
Use of PL EnviroPrep columns permits higher sample loadings and fraction yields to be obtained, particularly useful for looking at low levels of pollutants.
PL EnviroPrep preparative columns with the 10um particle size and 100A pore size offer high resolution and high loading through optimisation of the particle size distribution.
