  1. Ambient and SourceTechnologyIntegration Dennis K. Mikel EPA-OAQPS-AQAD

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

  3. 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

  4. 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!

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

  7. 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

  8. 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.

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

  10. 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

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