In this work, a "brick" size miniature mass spectrometer (28 cm × 21 16 cm) was developed and characterized, which enabled by the development of new frequency scanning technique. Different from conventional voltage method or digital waveforms used on ion trap, sinusoidal technique to drive linear trap brick (BMS). Both an in-vacuum plasma ionization source electrospray were coupled with BMS for analyses volatile nonvolatile samples. Stability diagram, sensitivity, resolution, range explored....
Previously, a miniature mass spectrometer driven by sinusoidal frequency scanning technique, named as Brick spectrometer, was developed in our lab (Jiang et al. Anal. Chem. 2017, 89, 5578). The technique enabled miniaturized electronics and broader range, but it also limited reduced resolution sensitivity due to relatively low operating radio (rf) voltage comparison with the conventional technique. To improve performances of quadrupole enhanced dipolar resonance ejection (QE-dipolar...
One of the main challenges analyzing intact proteins on an ion trap mass spectrometer is range limitation, especially for miniature spectrometers. In this study, a high-field frequency scanning spectrometer, namely "Brick" was developed to analyze proteins. A high-voltage broadband radio (rf) amplifier designed with maximum output 900 Vp-p over 130-700 kHz. Compared 600 rf equipped in conventional instrument could be extended from 2000 8000 Th. Sensitivity and resolution native protein...
