We refer to any sample in a gaseous state at room temperature, collected without processing in containers such as bags, glass ampoules, or sulfinert-treated metal cylinders (available for hire on request), as gas matrices.
Samples may come from gas cylinders, but they may also be medical gases, the ‘gaseous’ part of food packaging (the top of a water bottle, the gas in a ham package, etc.) or gases emitted by a material (foam, plastic, etc.) or a liquid (perfume, oil, etc.).
Quad-Lab lab can analyze most gaseous matrices and offers the following services:
- supply of gas sampling containers according to your requirements;
- design and manufacture of gas extraction devices for hermetically sealed systems: aerosols, cans, food packaging, heaters, etc.
- a complete range of analyses for pure gases or mixtures, such as
- quantification of gaseous compounds: carbon dioxide (CO₂), hydrogen (H2), nitrogen (N2), oxygen (O₂), etc ;
- quantification of gaseous hydrocarbons: C1 to C5 alkanes, alkenes ;
- the quantification of several specific gases: sulfur hexafluoride (SF6), greenhouse gases, freons, … ;
- search for volatile organic compounds (VOCs) without a predefined list: VOC screening;
- calculation of parameters such as calorific values (HCV and HCV) and density.
