Flowing Atmospheric Pressure Afterglow

The needle-Flowing Atmospheric Pressure Afterglow (n-FAPA) is a miniaturized plasma device with Ambient Desorption/Ionization capabilities. It is generated in flowing He using two concentric electrodes: a stainless steel capillary tube (outer electrode), and a hypodermic needle with a bevel-cut edge (inner electrode).
