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

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 compressedand injected directly on column in a specially designed GC• GC is constructed within a fully functional personal computer•FID-VOC sensitivity of 50 ppt
