The design and analysis of isotope experiments
The American Journal of Medicine, 1960Abstract The importance of quantitative isotope technics in the study the metabolism of the whole body is discussed. A number of simple model systems are analyzed and approximate numerical solutions are presented for the investigator who does not require the added precision of more complex mathematical analyses.

A Mass Spectrometer for Isotope and Gas Analysis
Review of Scientific Instruments, 1947A mass spectrometer suitable for routine isotope analyses of the lighter elements is described. Complete electronic circuits are given. An all metal mass spectrometer tube is employed. A null method of determining relative abundances of the elements carbon, nitrogen, and oxygen is used.
