Trace analysis by metastable energy transfer for atomic luminescence

Abstract

Combining eq A8, All, and A12 r¡ = L2/(wAp) (A13) establishes a relation between the characteristic decay time and the ionic mobility in terms of the distance between the probes and the applied potential. Using eq A10 and A13 N¡ = n exp(-x/L) -L < x < L (A14) which agrees with the solution found for the so-called plasma-capacitor in the limit of low charge density (23). Due to the absence of the diffusion term in eq A5, the charge density does not obey the boundary conditions 1V¡(±L) = 0.

Atmospheric pressure active nitrogen (APAN) - a new source for analytical emission spectroscopy

“…All of the elements which have visually been observed to give characteristic atomic and/or molecular emission in low pressure active nitrogen afterglows are illustrated in Figure 33. Detection of several metallic elements at trace levels by thermal vaporization of the sample into an active nitrogen afterglow has recently been described (117,118). Construction of a thermal vaporization unit for the APAN system would be most advantageous for evaluating the feasibility of detecting elements which have not been investigated up to this time.…”
