Molecular emission cavity analysis
Autor: Alan Townshend, Stanley Bogdanski, Ronald Belcher
Publikováno v: Analytica Chimica Acta. 207:355-359
Apparatus is disclosed for analysing a sample of matter by emission spectroscopy. The apparatus includes an emission promoting structure defining a sheltered region whereby a reactant vapour can be retained within the region whilst being exposed to f

Determination of manganese in precipitated calcium carbonate samples using candoluminescence spectrophotometry: some problems associated with the preparation of standards
Autor: Ronald Belcher, Helena Puzanowsha-Tarasiewicz, Malcolm H. Lloyd, E. Roy Clark
Publikováno v: The Analyst. 108:1466
The intense yellow candoluminescence given by manganese in a calcium oxide - calcium sulphate matrix when placed in a hydrogen - nitrogen - air flame has been used to investigate the determination of manganese (in the range 0.2–0.6 p.p.m.) in comme
