Master Student Internship in the Development of quantitative methods for the analysis of pesticides and degradation products in water samples (M/F)

Luxembourg Institute of Science and Technology (LIST)

Esch-sur-Alzette, Luxembourg

Context of intervention

The intern will participate in the implementation of new methods of data analysis and processing and the improvement of existing methods. After validation by the Green Tech Platform Engineers specialized in analysis of organic contaminants, these methodological developments can be exploited in future projects or collaborations in the field of multiresidue analysis (especially pesticides and degradation products).

Description

The GreenTech Platform the Environmental Research and Technology Platform (ERIN Department, Luxembourg Institute of Science and Technology) offers a 5-month internship for a Master 2 student in the field of chemical analysis of micropollutants in water samples.

Pesticides, as well as many xenobiotic compounds, are known to be widespread in the environment and especially in the water cycle, including rivers and groundwater. In order to get significant information on the origins and fate of these organic pollutants, it is of prime importance to develop modern analytical techniques offering the highest sensitivity and the widest range of target compounds. Additionally, regular updates of the methods are required to consider the evolution of pesticide usage, by targeting new pesticides or degradation products.

The Intern will be asked to improve existing methods for the analysis of pesticides, based on on-line Solid-Phase Extraction coupled to Liquid Chromatography and tandem Mass Spectrometry (SPE-LC-MS/MS). The main objective is to expand the number of target analytes by adding challenging pesticides (polar or ionic) and known degradation products. Technical improvements will also be explored, like the optimisation of LC stationary phase and the fine-tuning of MS source parameters. In a second part, the presence of suspected metabolites or degradation products will be investigated in real samples (ground water, river water), by means of semi-targeted full-scan analyses using High-Resolution MS.
