EXPLANATION OF THE TABLES Each of the Applications sections, 2.1 t o 2.8 inclusive, is accompanied by a table which summarises the principal analytical features of the references from which the corresponding section is compiled. These Applications Tables form a convenient source of information for analysts interested in particular elements, matrices, sample treatments or atomisation systems. In many cases, sufficient detail is given for the analytical procedure t o be followed; absence of such detail usually means that the information was not directly available to the compiler of the table and hence the original reference should be consulted in such cases. The column headings of the tables and the various abbreviations employed are explained below. ELEMENT Xnm MATRIX CONCENTRATION TECH.The elements determined are listed in the alphabetical order of their chemical symbols, except that, for space economy, multi-element applications (5 elements or more) are given at the end of each table. The wavelength, in nanometres, at which the analysis was performed. An indication, necessarily brief, is given of the material analysed. The concentration range of the element in the matrix or original sample, expressed as % or pg/g for solids and mg/l for liquids. The atomic spectroscopy technique is indicated by either A (absorption), E (emission) or F (Fluorescence). 45 Part 11: Methodology ANALYTE The analyte is defined as the sample as it is presented to the analytical instrument, and its form is indicated by either S (solid), L (liquid) or G (gas or vapour). “d.1.” = detection limit in the analyte. SAMPLE TREATMENT A brief indication is given of the sample pre-treatment, if ATOMIS ATION REF. 46 any, required to produce the analyte. Abbreviations, where used, follow the Society for Analytical Chemistry list as given in “Analytical Abstracts.” The atomisation process is indicated by the abbreviations: a (arc), s (spark), f (flame) and p (plasma), usually with some additional descriptive detail. The number refers t o the main Reference List, which gives the title of the paper and the name of the author(s), with address.
