On-site GC-MS Analysis

GC-MS analysis provides insight into quality of indoor and ambient air

The highest risk associated with VOC-contaminated soil is its impact on the quality of indoor and ambient air. VOCs are harmful to the health of local residents,as well as on-site employees.

On the basis of our expertise with MIP GC-MS measurements, we have developed a modified method for carrying out gas analyses. Here we go into the field to analyse the soil gas, indoor air, as well as the ambient air or industrial gas flows at the site itself.

Rapid on-site evaluation and measurement of VOCs

We use Vapor Pins ™ or soil gas probes to sample the soil gas. By capturing the air in gas bags or by directly connecting it to the GC-MS, we are able to instantly measure individual VOCs in unsaturated zones. This way we are able to very quickly investigate where, for example, the source zone of a soil contamination is located and to plan any subsequent instigations with a better focus. For example, we apply this approach as an initial phase, prior to a detailed investigation using MIP GC-MS.

On the other hand, the On-site GC-MS Analysis is extremely well suited to monitoring VOCs within indoor or ambient air. The analysis of individual components makes it possible to anticipate the highly divergent limit values of air pollution and take focused measures accordingly.

The extensive sampling system also makes it possible to subsequently use the GC-MS to monitor various gas lines from the different sampling points. 

Real-time evaluation of individual VOCs

As an engineering firm or a soil investigation firm, you naturally want to keep your finger on the pulse during such assignments. From this perspective, EnISSA focuses on dynamic sampling and real-time follow-up of the values.

Your benefits All of the results of the on-site GC-MS are immediately available. Furthermore, the intensive sampling provides detailed insight into the concentrations, which enables you to specifically adjust the focus of the soil investigation or the soil remediation where necessary.

On-site metingen resulteren in een dynamische onderzoeksmethodiek

  • Lage detectielimieten voor verscheidene parameters
  • Gedetailleerde informatie over individuele verbindingen
  • Kosteneffectieve verzameling van meerdere honderden datapunten/dag
  • Directe beschikbaarheid van resultaten
  • Mogelijkheid om on the spot het onderzoek bij te sturen
  • Reductie van de doorlooptijd van het bodemonderzoeken

 

De gedetailleerde compound specifieke MIP-profielen maken we voor onze klanten heel visueel. Soms zelfs ook in 3D. Dit helpt hen in hun adviesrol naar klanten toe om de situatie van de verontreiniging helder te illustreren.

 

We kunnen dus stellen dat deze methodiek uiterst betrouwbare informatie oplevert, wat adviseurs helpt bij het opmaken van het CSM en wat op zijn beurt weer leidt tot een geslaagd saneringsproject in the end.
