Group of Analytical Chemistry and Materials for Environnement and Health

The group of Analytical Chemistry and Materials for Environnement and Health develops analytical methods for the detection of organic molecules mainly in the air but also in other environmental matrices (water, soils). The activities of the team are structured around 3 research axes:

• Axis 1: On-line analytical methods via microfluidic devices for the quantification of air pollutants

On-line methods combine sampling, species separation or selective derivatization reaction and near-real time detection. Microfluidics allows to obtain compact and portable devices.

Keywords: Volatile Organic Compounds (VOC), formaldehyde, aldehydes, benzene, BTEX, microfluidics, portable instruments, prototyping.

Contact: Dr. Stéphane Le Calvé

• Axis 2: Off-line analysis methods via chromatographic techniques

The off-line methods consist in taking the sample on site and analyzing it once back to the laboratory. The active or passive air samplings are performed with adsorbent tubes.

Keywords: Semi-volatile organic compounds (SVOC), pesticides, PAHs.

Contacts: Prof. Maurice Millet and Dr. Olivier Delhomme

• Axis 3: Adsorption study of organic molecules on various materials

The aim is to study the adsorption processes of organic molecules on different adsorbents (zeolites, MOF, etc.) either in air using representative controlled conditions (temperature, relative humidity and pollutant concentrations) or in water.

Mots clés : Adsorption, désorption, Composés Organiques Volatils (COV), formaldéhyde, aldéhydes, benzène, BTEX, BET, courbe de perçage.

Keywords: Adsorption, desorption, Volatile Organic Compounds (VOCs), formaldehyde, aldehydes, benzene, BTEX, BET, breakthrough curve.

The CAMATES team is committed to providing the best possible working conditions for all its members.

With this in mind, it boasts state-of-the-art equipment, including recent instruments such as LC/MS, GC/MS-MS, and GC/MS, enabling high-quality research to be carried out.

Aware of the importance of a pleasant working environment all year round, the team has also equipped its laboratories with reversible air-conditioning systems installed in recent years.

In 2024, a convivial area was created for relaxation, coffee breaks and meals. Coffee is provided free of charge to all members.

The offices are equipped with modern workstations, including computers running Windows 10 or 11, as well as large screens (24 or 27 inches and more), ensuring optimum comfort.

This initiative is part of a continuous improvement process, with a focus on incorporating all suggestions relevant to the team's well-being and efficiency.

• Convivial space

• Examples of recent analytical instruments
