1938 W. B. Meldrum & E. W. Flosdorf Qualitative Anal. Inorg. Materials 1. 7 Microanalysis may be applied when the amount of material available..is very small... Many of the reactions are essentially the same as those used in the systematic macroanalysis.
1955 C. R. N. Strouts et al. Analyt. Chem. I. xiv. 314 The economy of time afforded by many micro procedures favours their adoption even when the amount of sample available is sufficient for macroanalysis.
1966 McGraw-Hill Encycl. Sci. & Technol. (rev. ed.) XI. 143/1 Methods of quantitative analysis vary with the amount of sample taken and of constituent being determined. A macroanalysis (decigram analysis) uses a sample of about 0·1–0·5 gram.
