molar-mass exclusion limit

in polymers
https://doi.org/10.1351/goldbook.M03978
The maximum value of the molar mass or
molecular weight
of molecules or particles, in a specific
polymer solvent
system, that can enter into the pores of the porous non-adsorbing material used in size-
exclusion chromatography
. For particles with molar mass or
molecular weight
larger than the exclusion limit the separation effect of the size-
exclusion chromatography
vanishes.
