<p>For use in a system for analyzing sample constituents by metastable transfer emission spectroscopy, an improved apparatus for mixing a sample gas with a metastable gas. The apparatus provides an unobstructed path for the flow of sample gas so as to minimize deposition of the sample (10) on walls of the apparatus. The apparatus may comprise an annular manifold (14) coaxially mounted around a conduit (32) through which flows the sample (10), or it may comprise a collar (34) detachably connected in line with such a conduit (32). </p> |
