Figure 6. Progress in various branches of atomic spectrometry would be aided tre­mendously by the introduction of a low-cost laser tunable down to 200 nm and an ar­ray of many thousands of photodiodes, each 1 μνη wide

development of dc and M I P sources for t he analysis of l iquids.

T h e fate of o ther innovat ions can be decided only after fur ther research and evaluation. T h e au thor sees l i t t le need for high-resolution I C P - A E S and is skeptical abou t direct in t roduc­tion of solids into I C P or E T A . As in­dicated, t he glow discharge and the hollow-cathode discharge have more potent ia l for solids analysis, b u t even then the performance of X- ray fluo­rescence will be ha rd to beat . Other developments await progress in phys­ics (Figure 6). For example , the inven­tion of a cheap, s table , t unab le UV la­ser will have an immedia te effect on the future posit ion of a tomic fluores­

cence, LEI , and even mul t i e lement AAS. Likewise, improved mul t ichan­nel de tec tors will drast ical ly al ter t he design of mul t i e lement A E S ins t ru­men t s .

Leo de Galan studied physical and analytical chemistry at the Universi­ty of Amsterdam, where he received his Ph.D. in 1965. After a postdoctor­al year at the University of Florida he joined the Delft University of Tech­nology, where he was appointed pro­fessor of analytical chemistry in 1972. His research interests are atomic spectrometry, liquid chromatography, computerized optimization, and in­strument development.
