Metal moments

Metallic and other elemental impurities in oral pharmaceutical products can be detected and determined with precision and speed using axial viewed inductively coupled plasma atomic emission spectrometry with ultrasonic nebulisation, according to a team at the Quantum Analytics Group, based in Bridgewater, New Jersey, USA. Given that new regulations are in place in the USA and elsewhere to control specific daily exposures to various heavy metals, it is essential that the tools exist for quality control, assurance, and regulatory compliance. The team hopes their technique will overcome some of the limitations of earlier techniques as well as being more readily available to laboratories worldwide in comparison with other techniques.
