Miniature, Monolithic, Fully Additively Manufactured Glass-Ceramic Quadrupole Mass Filters for Point-of-Care Mass Spectrometry

We report the design, fabrication, and preliminary characterization of the first fully additively manufactured, miniature, ceramic quadrupole mass filters (QMFs). Through a monolithic design, microstructured digital light processing of glass-ceramic feedstock, and electroless metal plating, this work demonstrates the feasibility of additive manufacturing to create compact mass filters for point-of-care (PoC) mass spectrometry systems. Furthermore, this work demonstrates the practicality of a novel, RF-only method of electrically driving quadrupole mass filters.
