TY - JOUR T1 - Isotopic carbon: Techniques in its measurement and chemical manipulation Y1 - 1949/09/03 N1 - 10.1001/jama.1949.02910010107023 JO - Journal of the American Medical Association SP - 105 EP - 105 VL - 141 IS - 1 N2 - One of the most difficult and yet important present day fields of research in which to obtain adequate technical information is that concerned with isotopes. The spectacular advances that have been made in many fields of science, principally biochemistry, leave the neophyte deeply impressed with the importance of this tool, and at the same time he is aware that his ignorance of the general principles and technics prevents him from applying these extremely useful isotopes to his own field of research. "Isotopic Carbon," by Calvin and others, is an exceptionally successful and well written manual for initiating the average investigator into the isotopic field. The book adequately describes the preparation of the carbon isotopes, their detection and instrumentation, and the methods employed in handling and preparing samples for analysis. There is also included a concise and accurate description of the methods of preparation of specific compounds, labeled with isotopic carbon, SN - 0002-9955 M3 - doi: 10.1001/jama.1949.02910010107023 UR - http://dx.doi.org/10.1001/jama.1949.02910010107023 ER -
