• Ionic Chromatograph • Gas and liquid chromatographs • Mass spectrometers • Level 2 Laboratory for Bacteria
This infrastructure measures trace elements in a wide variety of natural matrices ranging from water or soil samples to cellular fractions of living organisms. The laboratory includes: 1) a quadrupole mass spectrometer coupled to an inductive plasma (ICP-MS) 2) a high performance liquid chromatograph (HPLC) 3) an ultracentrifuge 4) two radiation counters (gamma counter and liquid scintillation counter)
This laboratory is used in particular to carry out research work on understanding the environmental fate of energetic materials. The laboratory consists of two experimental pans, the size of which makes it possible to carry out restoration experiments similar to field conditions, but under controlled experimental conditions. These tanks can contain 4 to 9 m3 of soil from contaminated sites or clean soils to which specific contaminants can be added.
This laboratory aims to develop electrolytic techniques and oxidative processes to improve municipal and industrial wastewater treatment systems or replace conventional low efficiency technologies to remove refractory, inorganic and microbial organic contaminants. It includes 4 facilities: - Laboratory treatment and control units - Analytical instrumentation units - Assembly of units, storage of reagents, installation ovens and scales - For heavy lab
This laboratory consists of a physical model of a municipal drinking water distribution network aimed at better management of these networks. The infrastructure replicates a typical sector of a municipal drinking water system. The pipes are about 2/3 of the actual diameter and pressure of a real network. The network is equipped with numerous sensors (flow, pressure, conductivity), pressure regulators, isolation valves and faucets (to simulate water usage or leaks) that are all connected to a central computer system . The assembly is designed to be more versatile.
A mass spectrometry service is offered to the scientific community for the identification of organic molecules, the analysis of natural products, the quantification of metabolites of pharmaceutical products, the analysis of trace pollutants, the determination of the molecular weight of proteins, the sequencing of peptides. The service includes, among others, a Micromass Quattro II triple quadrupole equipped with gas and liquid chromatography interfaces. It can be operated in positive and negative mode and carry out a mass scan up to 4000 m / z. The mass spectrometry service can perform a variety of MS / MS experiments such as daughter ion, parent ion and neutral fragment loss analysis. Various ionization modes such as electronic impact (EI), chemical ionization (CI), chemical ionization at atmospheric pressure (APCI), electrospray and nanospray can be used. It has an interface for gas chromatography with an HP 6890 gas chromatograph and an interface for HPLC HP 1100 liquid chromatography equipped with an automatic injector and a UV detector.
Analysis of trace metals in liquid or solid samples (biological tissues, suspended matter, sediments, soils) and bio-optical analysis. Research focuses on the path of toxic metals in the food chain, the bioavailability of contaminants, the impacts of anthropogenic activities and the assessment of the sensitivity of the natural environment. The main equipment is as follows: Particle and radioactivity counters (beta and gamma emissions); Atomic and mass emission spectrometers, by inductively coupled plasma (ICP-AES and ICP-MS); Liquid, gas and ion chromatography devices (HPLC, LC-MS-MS, GC, GC-MS); ICP-MS coupled to an HPLC; Mercury analyzer.
The service is able to meet several needs in the animal, plant or microbial fields, including: • Research and identification of viruses from all sources; • Research and identification (Gram-positive or Gram-negative) and description of bacteria from all sources • Research and identification of contaminants (eg mycoplasma) in clinical specimens or cell cultures • Immunoelectromicroscopy with or without colloidal gold on a liquid sample (negative staining) or on cell sections (pre- or post-embedding techniques) • Quality control of viral fractions of density gradients • Cell morphology on thin sections • Quantification of viruses (eg Retrovirus) using latex spheres of known concentration by negative staining. • Quality control of biological products released to municipal sewage • Research of Retrovirus in cells, identification and count of the proportion of infected cells (cell sections)
These laboratories make it possible to analyze water samples by colorimetry, fluorometry, spectroscopy, radioisotopy and chromatography, as well as to analyze organic compounds and trace metals present in different matrices (water, effluents, sewage sludge, soils, sediments, biological tissues), and finally, to analyze the elements present in solid samples (rocks, soils, sediments, sludge). X-ray microfluorescence scanning: Non-destructive x-ray analyzes coupled with chemical X-ray fluorescence analysis of rocks, soils and sediments. Scanning electron microscopy: Production of high resolution images of the surface and composition of a sample using technology using electron-matter interactions.
