The article refers to a prior work where an ion implanter used mass-spectrometry to prepare an isotopically pure beam. I think it is common for ion implanters to have a mass filter to keep various impurities out.
The mentioned in the article silicon-based kilogram standard used centrifuge-enriched material. I think it was bought from some boutique isotope separation company.
