As part of the SAFESIDE project, a portable gas chromatography-mass spectrometry (GC / MS) system was purchased in order to make comparative tests with the developed prototypes.
This equipment allows to obtain qualitative and quantitative laboratory quality results, in the field, in less than 20 minutes. It allows the identification and quantification of volatile organic compounds and some semi-volatile organic compounds. These compounds may for example be emitted by industrial processes (use of solvents, channeled or diffuse emissions), combustion phenomena whether intentional or not (fossil fuel use, fire, explosion), toxic chemicals (operations storage or transfer, toxic waste), or during incidents / accidents involving chemicals (transport of toxic materials).
This instrument is sensitive and very precise since it gives the possibility of measuring quantities of the order of μg / m3 and ng / m3 thus giving access to information on the degree of danger. It allows you to make quick decisions affecting health and safety.
In the frame of the project SAFESIDE, a portable analysis system has been used for inter-comparison with the systems developed within the project.
This system can be deployed on the field in 30 minutes and permits to get quantitative information with laboratory quality.
It permits the simultaneous analysis of principal gases of combustion: CO2, O2, CO, NOx and SO2 at a frequency of 1 Hz. The PG-350 E includes 3 detectors for the following standards: SRM for NOx (chemiluminescence), for CO/CO2 (Infrared) and O2 (Paramagnetic).
Depending on the characteristics of the effluents to be analyzed (dust, humidity, temperature), it can be combined with a portable pre-treatment module (PSS-, M&C Tech Group) and completed by a total hydrocarbons measurement (Graphite 52M, Envea).
These devices can be implemented by le Centre Commun de Mesures à l’Université du Littoral Côte d’Opale (Dunkirk site) which offers a delivery service for industry and research.
