Abstract: | Molecular emission cavity analysis (MECA) is shown to be useful for selective detection of sulphur or phosphorus compounds at the nanogram level in g.l.c. effluents. Introduction of a small oxygen flow into the cavity allows many other elements (e.g. Si, As, Sb, N, C) to be detected. The detection of microgram amounts of silylated amino acids is possible by measuring their SiO emission in the cavity at 580 nm. |
