“…These instruments, in conjunction with modern combustion techniques, are used for the rapid determination of sulfur (i.e., in several minutes), in practically any class of materials at concentrations ranging from a few ppm up to the major constituent level. Although the field has been comprehensively covered in relevant books (1-9) and in reviews (10)(11)(12)(13)(14)(15)(16)(17)(18), supplemented by the "Annual Reviews of Analytical Chemistry," little detailed information is available on the many specialized commercial instruments used for the determination of sulfur, as pointed out in a recent critical review (14). This situation has been created mainly by the geographic and linguistic separation of North America and Europe.…”
