In which of the following techniques the gaseous ions are subjected to two or more sequential stages of mass analysis according to the m/z ratio?

In which of the following techniques the gaseous ions are subjected to two or more sequential stages of mass analysis according to the m/z ratio? Correct Answer Tandem mass spectrometry

In tandem mass spectrometry the gaseous ions are subjected to two or more sequential stages of mass analysis according to the m/z ratio. This technique is also called as MS-MS. A particular ion from the spectrum is selected in the first MS and then it is fragmented in the collision box and selected in the second MS.
