Parallel Pseudo-MRM on the "brick" miniature mass spectrometer for high throughput multi-target screening.

With increasingly improved analytical performances, miniature mass spectrometers are expandingly applied in more application scenarios. The capability of high throughput analysis of multi-targets is a crucial function of a miniature mass spectrometer, especially for in-situ applications. As a powerful method for target screening, multiple reaction monitoring (MRM) was conventionally realized on triple quadrupole (QQQ) mass spectrometers.
