摘要：

This paper reviews the current state of molecular mass determination for fossil fuel materials by chromatographic methods and describes improvements which can be made to both the chromatographic separation and the detection of eluting material. Most significantly, N-methyl-2-pyrrolidinone (NMP) offers a number of advantages as a mobile phase in the size-exclusion chromatography (SEC) of coal derivatives. Much more coal-derived material dissolves in NMP and solute-column packing interactions common with SEC solvents such as tetrahydrofuran are much reduced. NMP is compatible with UV absorption and UV fluorescence detection.
