Gel permeation chromatography of low molecular weight materials with high efficiency columns

“…It has found extensive use in determining the molecular weight distribution of high molecular weight polymers. The great volume of literature on this application has been adequately covered in a number of review articles (2)(3)(4). Gel permeation chromatography is essentially a form of liquid chromatography in which solute molecules are selectively retarded as a result of their permeation into solvent filled pores in the column packing.…”

Gas chromatography

“…The 1973 applied review issue of Analytical Chemistry cites several hundred references to applications of gas chromatography published during 1971 and 1972 in the fields of air pollution (621), clinical chemistry (305), coatings (834), essential oils and related products (345), food (934), pesticide residues (854), petroleum (480), pharmaceuticals and related drugs (172), high polymers (597), rubber (898), and solid and gaseous fuels (376).…”
