PROBING METHOD USING ION TRAP MASS SPECTROMETER AND PROBING DEVICE

摘要

A probing device based on mass spectrometry, wherein a fast screening is conducted by using a step (201) of acquiring mass spectrum and a step (202) of judging whether or not an intrinsic m/z ion exists. Switching is made, for scrutinizing, to a step (203) of conducting a tandem mass spectrometry depending on the judged result in the judging step (202). A warning is triggered (205) from the result obtained in the tandem mass spectrometry via a step (204) of judging whether or not an intrinsic m/z ion exists and according to the judgment result. Whereby, a fast and substantially error-free probing is made possible.
