Some features are described of a 180° mass spectrometer designed for isotope abundance measurement. The ion current is amplified by an a.c. amplifier and the method of measurement, noise origins and circuits for stabilizing the ion beam are discussed. The accuracy and range are sufficient for the majority of stable isotopic tracer experiments with carbon, nitrogen and oxygen.
