Wastewater from coal-fired power plants is linked to a wide range of environmental and human health concerns. Measuring low levels of toxic trace metals in these wastewaters is complicated, however, by high levels of interfering matrix elements. A new EPA method using ICP-MS addresses this analytical challenge.

The Faraday cup has been associated with mass spectrometry since the first instruments were assembled and continues to be used today. Here's how it works.

Temperature measurements can be made using spectral features such as the position, linewidth, and intensity of the Raman signal associated with specific optical phonon modes. Each of these spectral characteristics offers particular advantages, depending on the type of device and operational considerations.
