The analysis of chlorinated organic insecticides by partition chromatography on paper and on cellulose columns

“…With the reported application (Gordon, 1951) of the more sensitive micro-diffusion analysis of chloride (Conway, 1950) to insecticides, it may be possible to perform this estimation on narrow strips of paper using still smaller quantities of insecticides. It might also be possible to use direct photometry (McFarren, Brand & Rutkowski, 1951) for the measurement of spot density on the developed chromatogram.…”

Analytical chemistry

“…Radiochemical Analysis.-The application of radioactive isotopes, the analytical methods that have been developed, and instrumental methods of measurement have been reviewed. 242 The isotope-dilution method has been applied to biological materials.243 0. Giibeli and W. Kolb 244 discuss the quantitative analysis of radioactive substances by activity measurements, and have applied the method, by measurement of radon and thoron, to the hydroxide.…”

Neutron activation analysis applied to arsenic determination

“…The post-irradiation assay must be provided for each combination of matrix and trace elements. In many cases, Boyd, who published his war-time researches (20), and to the early USAEC program begun by Overman and Clark (111) (20,23,44,45,82,124,146,147,148,149) presented the basic principles of the method and the applications, in cluding experimental data.…”
