molecular beam mass spectrometry

MBMS measured H2O2 and OH densities as function of distance. The full lines represent results of the 2D axially symmetric fluid model of the species transport and reaction kinetics in the plasma effluent. The dotted, dashed and short dotted lines represent the model results for nini,H = 1 x 1013cm-3, nini,H = 1 x 1014cm-3 and nini,H = 2 x 1014cm-3 respectively. The line indicated by "diffusion only" shows the effect on nH2O2 due to radial diffusion losses only. Due to experimental constraints, HO2 was only measured for one distance point.

Quantifying plasma chemistry products at atmospheric pressure

By Georgia Longstaff on October 20, 2017

An atmospheric plasma produces many species. But which ones, and what role do they play? We take a closer look.
