RT Journal T1 Spectrochemical analysis in 1938: A companion book to "spectrochemical abstracts 1933-38." JF Journal of the American Medical Association JO Journal of the American Medical Association YR 1939 FD March 25 VO 112 IS 12 SP 1191 OP 1191 DO 10.1001/jama.1939.02800120077035 UL http://dx.doi.org/10.1001/jama.1939.02800120077035 AB Twyman, physicist to Adam Hilger Limited, manufacturer of optical instruments, has now presented to his fellow workers a "last minute" account of references pertaining to spectrochemical analysis. The monograph is divided into six sections and a subject index. Twyman makes a candid selection of the literature. The second chapter, on quantitative spectrochemical analysis with the microphotometer, is of importance because it is the field which receives most attention at present. Chemists, physicists and biologists interested in this branch of science need this booklet on their study table.
