Know Your Baseline. Stay Ahead.
In today’s regulatory landscape, chemical and polymer manufacturers face heightened scrutiny under the Hazardous Organic NESHAP (HON) Rule — not just for emissions, but for how well they understand and control them.
At RJ Lee Group, we address the critical question: “Where do you really stand?”
Our mobile laboratory, outfitted with Proton Transfer Reaction Time-of-Flight Mass Spectrometry (PTR-TOF-MS) and Aerosol Ionization Mass Spectrometry (AIMS) technologies, delivers real-time, ultra-trace measurement capability directly to your facility. With detection sensitivity down to the parts-per-trillion (ppt) level, RJ Lee Group provides the data clarity you need to stay ahead of compliance thresholds and uncover fugitive or process-related emissions before they escalate.
Why This Matters
- The HON Rule (40 CFR Part 63, Subpart HHH and others) governs hazardous organic NESHAP emissions from petrochemical, polymer, and chemical manufacturing facilities.
- EPA enforcement and consent decrees are increasingly targeting Ethylene Oxide (EtO), Chloroprene, 1,3-Butadiene, Vinyl Chloride, and Ethylene Dichloride, among others.
- Facilities can no longer rely solely on periodic grab sampling or delayed lab reports — real-time, high-frequency monitoring is now essential for continuous improvement and compliance assurance.
RJ Lee Group’s Mobile Advantage
Our Mobile PTR-TOF-MS/AIMS Laboratory Platform Offers: - Real-time emissions profiling at ppt/low-ppb levels - Rapid on-site deployment with minimal infrastructure needs - Detection and speciation of hundreds of VOCs and HAPs simultaneously - High temporal resolution for identifying process upsets or leaks - Fenceline to stack coverage for source attribution and root-cause analysis - Data transparency and defensibility for internal and regulatory reporting.
