The author sees little need for high-resolution ICP-AES and is skeptical about direct introduc- tion of solids into ICP or ETA. As in- dicated, the glow discharge and the hollow-cathode discharge have more potential for solids analysis, but even then the performance of X-ray fluo- rescence will be hard to beat. Other developments await progress in phys- ics (Figure 6). For example, the inven- tion of a cheap, stable, tunable UV la- ser will have an immediate effect on the future position of atomic fluores- cence, LEI, and even multielement AAS. Likewise, improved multichan- nel detectors will drastically alter the design of multielement AES instru- ments. References (1) O'Haver, T. C. Analyst 1984, 109, 211. (2) Littlejohn, Α.; Duncan, I.

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.
