Ambient and Source Technology Integration Dennis K. Mikel EPA-OAQPS-AQAD

Concept Why initiate technology integration? Limited Funds Limited Manpower Time and effort

Task #1 Team Building We formed an internal team –Ambient Air Monitoring Group –Measurement Technology Group –We looked at different technologies –Chose one we felt we could have success

Task #2 Initiate technology integration project We contacted: –Cooper Environmental – X-Ray Fluorescence (XRF) Experts –Met One Instruments – Beta Attenuation Monitors (BAM) Technology –California Air Resources Board - Operate Met One BAMs We created a partnership!

Technology Integration Cooper XRF Technology Met One EBAM Met One Mylar backed Tape – Teflon Coated

Results of Collaboration

Long Term Plan Development of the semi-continuous multi-metals for fence-line and ambient applications Lowering Detection Levels for formaldehyde and 1,3 BD using Cascade Lasers – ORD development Pneumatic Focusing Gas Chromatography

Multi-metals Fence-line – Ambient Applications The Xact Ambient Air Toxics Monitor (Xact AATM) measures the ambient concentration of metals Based on uses X-ray fluorescence Sampling times for this instrument range from one to four hours. The Xact AATM measures metals in the pg/m³ concentration range.

Uses Tunable Infrared Laser Differential Absorption Continuous automated operation Detection Limit (pptv) Formaldehyde 60 Butadiene 80 Acrolein 120 MID-IR Cascade Laser System

Pneumatic Focusing Gas Chromatography (PFGC) Air sample compressed and injected directly on column in a specially designed GC GC is constructed within a fully functional personal computer FID-VOC sensitivity of 50 ppt

Technology Integration Toolbox Research SBIR ORD An Intelligent Approach to Technology Integration!!! Collaborate with Vendors and S/L/T
