Handheld Low-Temperature Plasma Probe for Portable “Point-and-Shoot” Ambient Ionization Mass Spectrometry

We describe a handheld, wireless low-temperature plasma (LTP) ambient ionization source and its performance on a benchtop and a miniature mass spectrometer. The source, which is inexpensive to build and operate, is battery-powered and utilizes miniature helium cylinders or air as the discharge gas....
