tandem spectrometry

Tandem spectrometry is a technique in chemistry that combines two mass spectrometers to help determine the structure of complex molecules. In this process, a beam of ions from the first spectrometer is directed into a gas cell. Within this cell, collisions cause the ions to break apart. The resulting fragments are then analyzed by a second mass spectrometer, which produces a spectrum that is often easier to interpret. This method is an advancement in mass spectrometry, an analytical technique used to identify chemical substances by sorting gaseous ions based on their mass-to-charge ratios.12
