Abstract
While this paper is to a large degree targeted for those not familiar with mass spectrometry, [for an overview of mass spectrometry, a number of excellent websites are available, including http://base-peak.wiley.com/links/Resources/Educational_Resources], the primary focus is on the importance of mass spectrometry in ultimately protecting public health and minimizing risks of chemical exposure. Its other audience is those who practice in this specialized field.
