This study describes how interference-free, low-level analysis of toxic elements as well as major elements in particulate matter (PM), with an aerodynamic diameter of 2.5 μm or smaller, can be accomplished. Comparison study examples are given for two locations.
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.
This study reveals the potential of triple-quadrupole ICP-MS for reliable quantification of noble metals at ultratrace levels even in difficult matrices.The
effective use of reactive gases for interference removal and a thorough and effective protocol for sample preparation and handling are essential.
