This tutorial illustrates the most important definitions used in high-resolution mass spectrometry and clarifies the misconceptions surrounding some of the relevant terms used in this field.

The second installment of this two-part series illustrates further technical principles and applications of the most common mass analyzers used in bioanalytical laboratories today, as well as novel techniques and mass analyzer designs. Examples are based upon the authors' research in small molecule applications.

The analytical challenges in marine chemistry are numerous due to the large number of natural toxins and their metabolites, the highly toxic nature of many of these compounds, and increasingly stringent regulatory guidelines. This article gives an overview of some recently developed mass spectrometry techniques and their application to marine biotoxins.
