Mass spectroscopy is an analytical technique which involves ? a. production of gaseous ions from a sample b. separation of the gaseous ions c. measurement of the relative abundance of the gaseous ions d. all of the above

Answer 1

It is d.

In order to perform mass spectroscopy, a gaseous sample must first be ionized (a). The ions are then separated by a magnetic field based on their mass to charge ratio (b). The detector then determines the relative abundance of each ion (c), accomplishing all three tasks.
