Abstract
A simplified and portable design of the 180° deflection‐type mass spectroscope was developed for quantitative analyses in the mass range from 4 to 65. The principal features include an oscillating accelerating voltage, permanent magnetic field, the use of a.c. amplifiers, and an oscilloscope. Successful application has been made to fixed gas, liquid and solid samples, and continuously flowing gases with changing component concentration. Accuracy from isotope ratio determinations is of the order of 2–5 percent.Keywords
