Abstract:
The present invention provides a mass spectrometer comprising a sample inlet, an ionization source, a mass analyzer, and an ion detector, wherein the ionization source comprises a photoionization detector lamp. The invention also provides mass spectrometers comprising two photoionization detector lamps. The use of a photoionization detector lamp can provide an increase in the signal of detected compounds as compared to the signal of detected compounds obtained using a comparable mass spectrometer with a conventional electron pumped beam lamp.
