First, wavelength-dispersive spectrometry, in 1970 already securely established among instrumental analytical methods, has matured. Highly sophisticated, miniaturized, modular, solid-state circuitry has replaced elec tron-tube circuitry in the readout system. Computers are now widely used to program and control fully automated spectrometers and to store, process, and compute analytical concentrations directly and immediately from ac cumulated count data. Matrix effects have largely yielded to mathematical treatment. The problems associated with the ultralong-wavelength region have been largely surmounted. Indirect (association) methods have extended the applicability of x-ray spectrometry to the entire periodic table and even to certain classes of compounds. Modern commercial, computerized, auto matic, simultaneous x-ray spectrometers can index up to 60 specimens in turn into the measurement position and for each collect count data for up to 30 elements and read out the analytical results in 1--4 min-all corrected for absorption | | 出版日期 | Book 1975 | | 关键词 | Chromat; Lithium; Phosphor; Platin; X-ray; chemical analysis; circuit; energy; material; physics; qualitative | | 版次 | 1 | | doi | https://doi.org/10.1007/978-1-4613-4416-2 | | isbn_softcover | 978-1-4613-4418-6 | | isbn_ebook | 978-1-4613-4416-2 | | copyright | Plenum Press, New York 1975 |
