Analysis of organometallic compounds using ion trap mass spectrometry

Abstract

Ion traps are an increasingly common presence as mass analysers in commercial bench-top mass spectrometers. Such instruments, usually interfaced with electrospray ionisation or nanospray sources, are invariably aimed at organic and biological applications, such as in the analysis of proteins, pharmaceuticals, organics, biomarkers, metabolites, etc. However, the abilities of ion trap mass spectrometers (extraordinary sensitivity, good resolution, MS" for structural information) can be profitably employed in the analysis of inorganic and organometallic compounds. We highlight these abilities, identify various problems and suggest the areas that will perhaps benefit most from employment of ion trap instruments. (C) 2003 Elsevier B.V. All rights reserved.

Mass spectrometry

Mass spectrometry (MS) is an analytical technique that is used to measure the mass-to-charge ratio of ions. The results are presented as a mass spectrum, a plot of intensity as a function of the mass-to-charge ratio. Mass spectrometry is used in many different fields and is applied to pure samples as well as complex mixtures. A mass spectrum is a type of plot of the ion signal as a function of the mass-to-charge ratio.

Ion trap

An ion trap is a combination of electric and/or magnetic fields used to capture charged particles — known as ions — often in a system isolated from an external environment. Atomic and molecular ion traps have a number of applications in physics and chemistry such as precision mass spectrometry, improved atomic frequency standards, and quantum computing. In comparison to neutral atom traps, ion traps have deeper trapping potentials (up to several electronvolts) that do not depend on the internal electronic structure of a trapped ion.

Quadrupole ion trap

In experimental physics, a quadrupole ion trap or paul trap is a type of ion trap that uses dynamic electric fields to trap charged particles. They are also called radio frequency (RF) traps or Paul traps in honor of Wolfgang Paul, who invented the device and shared the Nobel Prize in Physics in 1989 for this work. It is used as a component of a mass spectrometer or a trapped ion quantum computer. A charged particle, such as an atomic or molecular ion, feels a force from an electric field.
