title: Robotic plasma probe ionization mass spectrometry (RoPPI-MS) of non-planar surfaces.
abstract: In this report, we present a robotic sample introduction/ionization system for mass spectrometry (MS) for spot analysis and imaging of non-planar surfaces. The system operates by probing the sample surface with an acupuncture needle, followed by direct plasma chemical ionization time-of-flight MS.
