The Austin Lab Group explores novel instrumentation and applications based on mass spectrometry.
There is significant drive to make mass spectrometers sufficiently small and portable that they can be carried to the sample, rather than bringing samples into the lab for analysis. The Austin Lab Group has accordingly pioneered the approach of making mass analyzers using lithographically patterned plates. The Group has made miniaturized radiofrequency quadrupole, toroidal, and linear ion traps using this approach, as well as an electrostatic ion beam trap. The Group is also developing charge detector arrays for mass analysis using patterned plates. The use of patterned plates rather than machined electrodes reduces cost while improving the precision and alignment of the electric field.
The Austin Lab Group also studies electrospray charging of micron-scale particles. Using mobility experiments we have demonstrated that bacterial spores can survive electrospray charging and desolvation. These spores can subsequently survive impacts against a dense surface at surprisingly high impact speeds. The Group has also demonstrated that electrospray can be used to electrically charge a variety of mineral types, including quartz, olivine, and chondrite. Electrically charging mineral grains may enable accelerating these particles to high velocities for laboratory simulations of cosmic dust impacts.
The Group has recently published an article on crash testing bacteria at 670 mph in the lab to see if spores could survive space travel. Check out the video below for more information.
