Aerosol MALDI of peptides and proteins in an ion trap mass spectrometer: Trapping, resolution and signal-to-noise

Single Particle Mass Spectrometry–Bioaerosol Analysis by MALDI MS

“…26) Researchers at Oak Ridge National Laboratory use an ion trap mass spectrometer and have reported the on-line detection of proteins and peptides, applying the matrix by evaporation and condensation onto the aerosol particles. 27,28) So far, no on-line analysis of bacteria containing aerosol particles has been reported by the researchers from Oak Ridge National Laboratory.…”

Derivation of mathematical expressions to define resonant ejection from square and sinusoidal wave ion traps

“…In a previous publication [18], we pushed resonant ejection to its limits in a 1 MHz SIT using the aerosol MALDI technique to produce ions inside the trap. Ions up to myoglobin (m/z = 16.9 kDa) were produced and trapped.…”

Numerical Simulations on Aerodynamic Focusing of Particles in a Wide Size Range of 30 nm–10 μm

“…First proposed by Liu et al (1995a,b), they have the advantage of being mechanical devices that can be manufactured easily without special electric control units. Submicron particle focusing technology using aerodynamic lenses has diverse applications, including effective aerosol inlets for aerosol mass spectrometers (Schreiner et al 1999;Jayne et al 2000;Zhang et al 2004;Lee et al 2005Lee et al , 2006Lee et al , 2008Liu et al, 2007), micropatterning and material synthesis (Fonzo et al 2000;Dong et al 2004;Qi et al 2010), and inlets for measuring the creation of biomaterials (Harris et al 2006).…”
