1931[see micro- 8 b]. 1946Belcher & Wilson Qualitative Inorg. Microanalysis i. 3 This does not arise on the micro scale, because of the larger amounts of ethanol used to ensure complete precipitation. 1956Nature 25 Feb. 378/2 Schindler's procedure, which was adapted to microscale working, was followed. 2–5 mgm. of vitamin B12 is dissolved in 500 µl. of 10 per cent aqueous ammonium chloride solution. 1961New Scientist 16 Mar. 670/3 These materials are, however, crude on a microscale—they are porous and they contain impurities. 1964N. G. Clark Mod. Org. Chem. xxiv. 496 It became imperative to develop techniques demanding smaller samples. This was achieved in 1911 by Pregl, using 1–5 mg of material (micro-scale). 1966D. G. Brandon Mod. Techniques Metallogr. 103 It is now possible to perform a very large number of metallurgical operations in [sic] a microscale inside the electron microscope. 1968[see macro-scale]. |
