Combined with appropriate selection of instrument components to reduce the sulfur background, ICP-MS using MS/MS with oxygen reaction cell gas can provide accurate low-level analysis of sulfur and sulfur isotope ratios in aqueous and organic matrices. This is useful in applications in life science, clinical research, pharmaceutical development, food safety, environmental monitoring, geochemistry, and petrochemistry.

Metallomics seeks to understand the metallobiochemistry of cells and organisms in health and disease. This article explains the principle of laser ablation–inductively coupled plasma–mass spectrometry (LA-ICP-MS) for imaging applications and highlights its potential to provide additional insights in bioanalysis and metallomics.

Inductively coupled plasma–atomic emission spectroscopy (ICP-AES) relies on the use of a peristaltic pump for sample introduction. Here, two conventional peristaltic pumps are compared with a new pump based on the “easy click” principle for the analytical figures of merit.
