COMPUTER-CONTROLLED INSTRUMENTATION FOR ACCURATE MASS DETERMINATION BY PEAK MATCHING IN MASS-SPECTROMETRY

Peak matching, although a tedious and somewhat subjective process, has long been used with sector mass spectrometers for accurate mass deter mination. Computer-assisted control and data acquisition can remove th e subjectivity and make the process faster and less tedious. The circu its for data acquisition and sweep generation and the data analysis pr ograms that provide these advantages are described. These can also be used, with minor modification, for peak ratio determinations.
