Abstract
A modern, automatic, sequential x-ray spectrometer collects count data at a rate of 30–100 s per element; semiautomatic and manual instruments are somewhat slower because the settings cannot be made as quickly. A modern, automatic, simultaneous spectrometer collects count data for up to 30 elements in 30–200 s; it has been remarked that simultaneous instruments collect data so fast that the readout time may become significant! An energy-dispersive spectrometer with a multichannel analyzer collects data for up to ~20 elements in 30 s to a few minutes. Clearly, specimen preparation is usually the time-limiting step that determines the sample throughput rate, and when the samples can be measured as received—or substantially so—x-ray spectrochemical analysis is very rapid indeed.
