A potential route to silicon for solar cells involves using an improved version of the carbothermic process to give an intermediate product capable of being upgraded by chemical and physical means to an acceptable end product. The compositional analysis of these intermediate and end products is discussed from the viewpoint of someone who must make research and development or business decisions based on information supplied by analysts. Methods are discussed for analyzing dopants (B and P), metals (Al, Fe, and others), and nonmetals (C, O, and normalSiC ). Adequate methods are available, except when trying to measure the sub‐ppm concentrations of metals present in the final silicon product. A plan is suggested for developing a quality assurance method for the time when the industry grows to the extent of requiring its own source of silicon rather than by‐products from the semiconductor industry.

“…These results illustrate the usefulness of rate nephelometry to characterize not only the macromolecular conjugates but also antibodies originating from a variety of sources with subtle differences in their binding characteristics toward the same antigen. In fact, Hudson et al (2) have described such an application in which rate nephelometry was used to quantitate avidity (Hcoe() and titer (Ccoef) of different types of antisera.…”

“…The sample matrix causes difficulties at the determination of boron in steels and metallic materials by ICP-AES and therefore it is removed by extraction of iron with diethyl ether [3] or hydroxide separation [4]. Boron was also separated by pyrohydrolysis as boric acid from steel, vanadium alloys, ferrosilicon and ferroniobium [5], distillation of boron fluoride or extraction with tetrabutyl-ammonium from niobium, silicon, tantalum, zirconium [6] and distillation of methyl borate [7]. If ICP-AES procedure is used, the higher boron contents (0.01 up to 2% B) in alloy steels can be determined without any separation from the sample matrix.…”

In this paper, samples were digested by high pressure digestion pots, reducing the loss of trace elements during the digestion process. The content of trace elements in Natural Huazi Mushroom such as Ca was determined by ICP-AES, and compared with the results of wet method, the two methods showed no obvious differences. High pressure nitrifying pot method relative standard deviation of Ca element is 3.36%; Wet method to determine the relative standard deviation of Ca elementt is 7.08%. Visible high pressure nitrifying pot method and treatment of samples of precision of the measuring precision and wet processing samples are relatively good, the measuring precision of the former better. The method was suitable for the determination of trace elements in edible fungi with the advantages of being simple, rapid, sensitive, stable and accurate etc., and the results were satisfactory.
