Morphology
The intended meaning (‘separates molecules by size’) cannot be transparently built from 'mole' (an amount defined by Avogadro’s number) + 'sieve' (a perforated tool), because 'mole' does not mean 'molecular' and the noun+ noun combination is not a standard compositional pattern. Additionally, the established term is 'molecular sieve' in English and in other languages, so a B1 learner who knows the constituent words would likely be confused or misinterpret the phrase rather than derive the intended meaning.
Etymology
Mole sieve may come from a short form of the phrase 'molecular sieve'; picture a kitchen sieve with very tiny holes that stop big bits but let tiny molecules pass. So a Mole sieve is used to 'filter' or 'clean' substances by size.
