摘要：

A versatile system for multielement analysis and analytical studies of noise sources, flames, modulation techniques, statistics of error propagation has been constructed. The instrument consisted of an EIMAC xenon arc lamp for fluorescence excitation, a flame (most commonly air/acetylene or nitrous oxide/acetylene), a wavelength modulated, slewed-scan monochromator with data acquisition by a photon counter. The entire instrument was under computer (PDP 11) control. Analytical figures of merit (detection limits and growth curves) for 25 elements are presented along with a discussion of instrumental design, flexibility, mode of modulation, operation. Applicability to real samples Is demonstrated with respect to trace metal analysis in jet engine oils (SOAP samples) and NBS Standard Reference Materials. © 1979, American Chemical Society.
