What Is the Basic Setup of a Tandem Mass Spectrometry

Multiple Choice

What is the basic setup of a tandem mass spectrometry analyzer?

A) Tandem mass spectrometry uses a UV laser to ionize small amounts of matrix and analyte that are directed toward mass analyzer.
B) Tandem mass spectrometry is primarily for complex compound analysis,while tandem mass spectrometry is used for elemental analysis only.
C) Tandem mass spectrometry uses an ion trap designed to trap ions in three dimensions instead of two dimensions as in a typical beam type of mass spectrometer.
D) Two beam type mass spectrometers are arranged sequentially in tandem mass spectrometry,with a "collision cell" placed between the two instruments.
