Abstract
A laser desorption chemical ionization mass spectrometer configuration has been previously reported (l). The system uses a short pulsed (40 nS) CO2 laser interfaced to a mass spectrometer (Dupont 491) which normally acquires spectra by continuous scanning of the magnetic field. In this article, the details of the timing circuitry which enables coordination of the laser pulse, mass scanning, and data acquisition are described.
