Scientists have introduced a statistical definition of the limit of detection (LOD) for calibration-free laser-induced breakdown spectroscopy (CF-LIBS). The study provides a robust framework for LOD determination, addressing the high LOD associated with LIBS and enabling more accurate trace element analysis.

In this third part of this four-part series on spectroscopy instrument components, we take a closer look at components used in atomic spectroscopy instrumentation—from beryllium and Kapton windows used in X-ray analysis to sampler and skimmer cones and plasma torches for ICP systems.
ICP-MS is increasingly being used to analyze complex matrices, but an ICP-MS instrument optimized for the highest sensitivity may not have the sufficient matrix tolerance to analyze high-salt samples. We describe a method to optimize plasma robustness and interference control for accurate, routine analysis of critical trace elements in undiluted seawater.
Brines from desalination plants are increasingly being seen as a source of valuable elements, such as lithium, rubidium, and cesium. We show how ICP-OES can be used to measure the concentrations of such elements in brines to assess the economic feasibility of their recovery.
