relative molecular-mass exclusion limit

synonym: molecular-weight exclusion limit
https://doi.org/10.1351/goldbook.09965
Maximum value of the relative molecular masses of components in a specific polymer solvent system that can enter into the pores of the porous non-adsorbing material used in size-exclusion chromatography.
Note: For particles with relative molar mass greater than the exclusion limit the separation effect of the size-exclusion chromatography vanishes.
