molar-mass exclusion limit

in polymers
The maximum value of the molar mass or @M04000@ of molecules or particles, in a specific @PT07189@ system, that can enter into the pores of the porous non-adsorbing material used in size-@E02261@. For particles with molar mass or @M04000@ larger than the exclusion limit the separation effect of the size-@E02261@ vanishes.
