Air Sampling Applications
Air sampling is used in many industrial and commercial sectors, and the technology used to execute a comprehensive air sampling and analysis plan with RJ Lee Group has several applications, including:
- Vapor Intrusion Studies
- Indoor Air Quality Testing
- Quality Control Evaluations
- Environmental Test Chamber Testing
- Headspace Sampling
- Industrial Emissions Evaluations
- Analyzing for the presence of asbestos, dust, metals, crystalline silica, PCBs, PNAs, and dioxins
Beryllium Testing
Accurate testing and analysis of Beryllium heavy metals from sources ranging from natural rock erosion to coal mining is a vital part of maintaining environmental health and safety for your organization. RJ Lee Group provides accurate reporting that details the origins of any trace beryllium and our consulting experts can help address and resolve issues.
RJ Lee Group’s testing methods comply with EPA, NIOSH, and OSHA standards.
Proton Transfer Mass Spectrometry (PTR-MS) measures low concentrations of VOCs in real-time, making it ideal for monitoring air quality and detecting contamination. RJ Lee Group uses PTR-MS to measure the presence of environmental hazards like secondhand smoke, anesthetic gases in hospitals, and trace amounts of contamination in industries that require a sterile workplace.
Our PTR-MS technology offers many advantages over traditional methods:
- No sample preparation
- Near Real-Time Analysis (Response time <100 ms)
- Instant measurement of contamination
- Changes in the air can be captured daily
- Very low limit of detection (LoD ~ 5 ppt) of VOCs
- Allows monitoring of any indoor/outdoor air in any environment
- Does not use carrier gases, which can dilute the sample
Mobile PTR-MS Vehicles
RJ Lee Group’s mobile PTR-MS laboratory provides rapid response and ongoing monitoring for outdoor locations to perform air sampling on-site for chemical producers, power plants, petroleum refineries, and other industrial businesses.
Our mobile PTR-MS laboratories can also record day-to-day emissions from motor vehicles in areas of concern or be deployed to provide real-time monitoring of air quality after a natural or industrial disaster to aid in remediation efforts.
When used in a remote operation, the PTR-MS can monitor:
- Long-range effects of VOCs, providing chemical concentration maps in real-time
- Waste incineration and biomass monitoring, such as brushfires and forest fires
- Agricultural applications, such as the impact of reactive trace gases above swamps, dairies, and feedlots, and the use of pesticides
- Airborne contaminant from an accident, spill, or unintentional discharge.
RJ Lee Group mobile laboratories are dispatched from our Pittsburgh, PA headquarters and our CBAL location in Pasco, WA.
Fenceline monitoring and root cause analysis
We recently completed fenceline measurements at four refineries and a chemical plant, measuring benzene and 1,3-butadiene in real time to parts per trillion and tracing hotspots back to leaks or processes within each facility. We also found compounds from adjacent facilities moving onto the properties.
Fenceline monitoring tells you a threshold was exceeded. Real-time measurement on a mobile platform can tell you why.
When a concentration rises, the team can move upwind, measure again, and narrow the area until an elevated reading at the property line resolves into a specific unit, a specific valve, or a source that is not on the site at all.
