Micropollutant monitoring

//

Passive sampling

 

Our services cover all aspects of monitoring studies, from study design to on-site deployment, including training in the use of passive samplers, analysis, data formatting and interpretation of results.

terrain

Study sizing / Project management

We support you in choosing the strategy to be implemented, drafting the call for tenders, monitoring the study and interpreting the data.

Field deployment

The installation and removal of samplers, as well as various in-situ measurements of physico-chemical parameters, is an integral part of our services.

Micropollutant analysis

Pesticides, pharmaceutical residues, hormones, metals, metalloids, etc. State-of-the-art analytical instruments (LC-MS QqQ, LC-MS Qtof, ICP-MS) offer a wide range of analyses and limits of quantification adapted to all media.

Training

With many years’ experience in passive samplers, the Ecométrique team can train you in their operational use.

Interpretation report

After an in-depth analysis and meticulous synthesis, we deliver optimized, tailor-made results.

Full studies

We also carry out complete studies, from sizing to deployment, including analysis and interpretation.

Our passive sampler

Our passive samplers, deployed and used under operational conditions, have demonstrated excellent reliability. They are designed to effectively sample a wide range of micropollutants, including pesticides, pharmaceutical residues, metals, polycyclic aromatic hydrocarbons (PAHs), perfluoroalkylated and polyfluoroalkylated substances (PFAS), and many others.

DGT

DGT® devices are passive samplers for metals and metalloids. When deployed, their diffusion layer controls the accumulation of target elements, facilitating the determination of concentrations in the medium. Thanks to the multiple fixing phases available, DGT® can measure a wide range of compounds (aluminum, copper, iron, arsenic, cadmium, selenium, manganese, etc.).

POCIS

Le POCIS (Polar Organic Chemical Integrative Sampler) est un échantillonneur passif adapté à la mesure des micropolluants hydrophiles comme peuvent l’être de nombreux pesticides, résidus pharmaceutiques ou hormones. Sa phase absorbante microporeuse lui permet de piéger et concentrer les molécules durant toute la durée d’exposition (15 jours en moyenne).

Chemcatcher

Chemcatcher devices, in their apolar version, can be used to sample “apolar” compounds such as PAHs (Polycyclic Aromatic Hydrocarbons) and PCBs (PolyChloroBpiheniles).

LO-DGT

The LO-DGT is a passive sampler combining the advantages of POCIS (large sampling area) and DGT (diffusive phase to control the arrival of compounds at the fixing phase). Applied for hormone sampling, it can also be used to monitor pharmaceutical residues.
