摘要
The use of size-exclusion chromatography to characterize complex mixtures of low-molecular-mass additives is presented. These antioxidant lubricant additives are oligomers derived from more than one monomer unit and have a molecular mass generally in the range 150-1000. The technique separates these mixtures into molecular mass regions, which produce a fingerprint characteristic of the product. The fingerprints are correlated with molecular structure using standards known to be present in the mixtures. The method can be used as a quality control tool and a research tool for product characterization. (C) 1999 Elsevier Science B.V. All rights reserved.
