Claim 14:
15. A computer program product, comprising a non-transitory tangible computer-readable storage medium whose contents include a program with instructions being executed on a processor so as to perform a method for calibrating a mass analyzer, comprising:
providing a system, wherein the system comprises one or more distinct software modules, and wherein the distinct software modules comprise a control module;
instructing an ion source device to ionize an analyte of a sample using the control module, producing analyte ions,
instructing a dual-purpose electron beam generating unit of the mass spectrometer located between the ion source device and a mass analyzer of the mass spectrometer, in a first mode, when the mass spectrometer is in mass spectrometry (MS) mode, to transmit the analyte ions to the mass analyzer directly or through one or more other units of the mass spectrometer for mass analysis using the control module,
instructing the dual-purpose electron beam generating unit, in the first mode, when the mass spectrometer is in mass spectrometry/mass spectrometry (MS/MS) mode, to fragment the analyte ions into product ions and transmit the product ions to the mass analyzer directly or through the one or more other units for mass analysis or to transmit the analyte ions to a collision cell of the mass spectrometer for fragmentation that, in turn, transmits resulting product ions to the mass analyzer for mass analysis using the control module, and
instructing the dual-purpose electron beam generating unit, in a second mode, to create ions of calibration compounds and transmit the calibration ions to the mass analyzer directly or through the one or more other units for mass analysis using the control module.
