This article describes the use of an in-line, autodilution, and autocalibration sample delivery system coupled to an inductively coupled plasma–mass spectrometry system to analyze a group of over-the-counter pharmaceutical products.

Bottled water has become increasingly popular over the past several years for convenience and safety. In some areas where publicly supplied tap water is contaminated or contains bacteria, this assumption is valid. However, in areas with clean tap water, the presence of bottled water can be controversial because it might be less clean than the local tap. This article discusses the analysis of inorganic contaminants in bottled water, including regulated contaminants and bromate. Detection limit considerations and speed of analysis also are discussed.
