ICP-MS Measurement

Overview

This section will focus upon considerations in developing an ICP-MS measurement procedure for those using a spectrometer employing a quadrupole mass filter. These instruments are relatively easy to operate, have good stability, and are the most common instruments used by trace elemental analytical laboratories. They also have a resolution of something less than 1 amu (atomic mass unit). These instruments are typically referred to as low resolution instruments.

Some other types of spectrometers will not be addressed in this guide. These include: a) spectrometers using magnetic fields to disperse the ion beams can operate up to a resolving power of 1 part in 10,000; b) time-of flight- spectrometers; c) and spectrometers utilizing ion-trap principles. For more detail on the quadrupole as well as the other types of ICP-MS spectrometers, I encourage you to refer to the following references:
