“…Additionally, each PFAS molecule will break down in a myriad of intermediate and/or end-products leading to a significant dilution of the initially present molecules. While industrial remediation and breakdown processes primarily focus on concentrated PFAS streams, these compounds are often present in the parts-per-trillion (ppt) range, i.e., extremely diluted, in water, soil and air [55]. This combination of complexity and low levels of starting PFAS and breakdown products significantly hampers the ultimate aim of closing the mass balance and thus the unraveling of full reaction mechanisms.…”

“…Quadrupoles used in benchtop GC-MS are typically operated in the mass range of 10-1000 Th [34]. Quantitative analysis of complex samples was usually performed on quadrupole MS [35][36][37]. However, a single quadrupole cannot achieve tandem mass spectrometry and requires a tandem-in-space configuration to enable MS/MS experiments.…”

Although a quadruple mass analyzer and an ion trap mass analyzer have complementary analytical features, they usually have different geometries, operational modes, and electronic control systems. As a continuous effort to extend its coverage, both quadrupole and ion trap operation modes were realized on a “brick” miniature mass spectrometer with a single mass analyzer. In the quadrupole operation mode, low-mass ions ranging from 31 to 502 Th can be analyzed. On the other hand, the ion trap mode can be utilized to cover ions with higher mass to charge ratios (up to 922 Th), as well as performing tandem mass spectrometry. To realize the multiplexing of both operation modes, a printed circuit board (PCB)-based multi-electrode quadrupole–ion trap mass analyzer was designed and integrated in the system. To cover both volatile and non-volatile molecules, two ionization sources were also implemented, including a nano electrospray ionization source and an in-vacuum plasma ionization source. Performances of the instrument operated in these two modes were characterized, such as mass resolution, sensitivity, and mass range. Results demonstrate that the combination of the quadrupole and ion trap operation modes can provide new capabilities when solving analytical problems.
