Most environmental GC analyses involve a sample cleanup procedure. For example, Schomberg (11) recommends optimized sample cleanup by using liquid chromatography with size exclusion, ion... [Pg.325]

Totally porous particles of relatively large particle sizes were widely used in low pressure liquid chromatography for many years. These column packings had good sample capacity but only limited efficiency accompanied by long separation times, due to the large size and unfavorable size distribution of the particles and the presence of relatively deep pores within the particles through whick sample molecules diffused in and out of very slowly. [Pg.675]
