Abstract
The present invention provides methods and electronic circuits for a chemical analyzer, for example, a mass spectrometer, which provide generated signals that are maintained to a required level of precision. A user may specify the required precision for the signals which operate the spectrometer and may specify the required precision for the mass analysis, either explicitly or by choosing a predefined configuration. The spectrometer will then generate the signals to the required precision despite changes in operating conditions, environmental conditions, component aging and degradation, or other nonfailure effects that otherwise affect analyzer calibration and signal output. The electronic circuits incorporate signal monitoring to maintain closed-loop signal control. The closed-loop control includes a feedback path which may include discrete components and may include software enabling a processor to adjust the generated signals to maintain the required precision of the signals and analysis. Further, the spectrometer may monitor signals and analyze and store data in order to predict future performance, including precision, analysis limitations, impending component degradation or fa…
