✦ Synopsis

Experiments to perform mass spectrometry with ion traps of submillimeter dimension are described. Several trap geometries amenable to microfabrication have been explored. In these experiments, vaporphase molecules were ionized by a pulse from a frequency-quadrupled Nd:YAG laser. The ions were trapped and mass analyzed by manipulating the radiofrequency voltages on the trap electrodes. Effects of trapping parameters on mass resolution and sensitivity are discussed.

Due to the varying toxicity the species of organotins in their widespread applications, it is important for analytical methods to address their speciation. Traditional methods call for the hydrolysis and subsequent derivatization of the organotins before analysis. These methods can be time-consuming
