MIP measurements with compact Geoprobe make indoor HRSC investigation possible at locations with limited space.
Soil contamination involving Volatile Organic Compounds (VOC’s) can pose health risks
to users, residents, neighbors, and passersby. Leveraging our expertise in
rapid GC-MS measurements using MIP technology, we have developed a tailored
methodology for on-site gas analysis. This allows us to analyze soil gas,
indoor air, ambient air, and industrial gas streams directly in the field,
enabling remediation teams to take swift and targeted action when necessary.
Using Vapor Pins™ or soil gas probes, we sample soil gas. By capturing the gas in tedlar bags or directly connecting it to the GC-MS, we can instantly measure individual VOCs in unsaturated zones. This approach quickly identifies the source zone of soil contamination, facilitating the planning of further targeted investigations. For example, we use this as a preliminary phase before conducting more detailed studies with MIP-GC-MS.
Additionally, on-site GC-MS analysis is highly effective for monitoring VOCs in indoor or ambient air. The ability to analyze individual components allows us to address the highly variable thresholds for air pollution and implement specific mitigation measures.
Thanks to the comprehensive sampling system, the GC-MS can even monitor multiple gas lines sequentially from various sampling points.
Through
dynamic sampling and real-time monitoring of measured values, all results from
our on-site GC-MS analysis are immediately available.
This intensive sampling provides a detailed understanding of concentrations,
allowing for precise adjustments to soil investigations or remediation
activities as and when needed.
