The “Plasma spectroscopies, hyphenated methods & speciation” group evaluates and develops spectroscopic tools and their hyphenations.
Two main fields of research are investigated : speciation methods and laser assisted spectroscopy whose applications are related to process control, sustainable chemistry and environmental issues.
Our work in laser assisted spectroscopy is mainly dedicated to:
Instrumental and strategy developments, such as calibration improvement, on laser ablation hyphenated to inductively coupled plasma with both optical and mass spectroscopy detection (LA-ICP OES or LA-ICP-MS) for complex liquid/solid samples (metals, plastics, material from petroleum industries) to gain in terms of detection limits and accuracy of measurements
We are working in Laser-induced breakdown spectroscopy (LIBS) to develop its potential for on line liquid analysis for process control or recycling materials sorting.
Speciation’s aim is to identify and quantify different chemical species of elements so as to evaluate their toxicity/ecotoxicity and biodisponibilty. These studies are applied both in environment, health and industrial issues. Our works in Speciation are focused on development of analytical methodologies based on innovative hyphenated techniques such as GC/LC -ICP-MS and LC2D – ICP-QQQ-MS.
