2 Introduction of a Revolutionary Direct Push Device CP-1000 XRF Cone Penetrometer

3 The EDXRF Underground Soils Soils Sediments Sediments Sludge Sludge And Many More… And Many More… CP-1000…The Worlds Only Tube Based Spectrometer Capable of Being Pushed Into…

4 Statement of Opportunity Cone Penetrometer Miscalculation Miscalculation Excavation & Sampling (example: Super-Fund Site Clean Up) Excavation & Sampling (example: Super-Fund Site Clean Up) Sub-surface characterization of soils and minerals is a necessary step in planning field activities. It is costly and often environmentally unfriendly. Inexpensive field solutions are desired to reduce costs. Additional Cost = Equipment Usage & Remobilization Additional Cost = Equipment Usage & Remobilization Creates Hazard Creates Hazard Disturbs Site Disturbs Site Wait On Lab Results Wait On Lab Results Others Others –Extended CEMS Usage –Site Expansion –Workers Comp/ Exposure Liability

5 Current Status of In Situ Soil Analysis Physical Data Probes Physical Data Probes –EC –Soil Typing –HC Organic Compound Probes Organic Compound Probes –MIP –LIF Push Probe Equipment Push Probe Equipment –Trucks –Trailers Elemental Analysis Probes Elemental Analysis Probes –None! –Take Sample & Send To Lab

6 CP-1000 Overview 3-D Sub-surface Characterization 3-D Sub-surface Characterization Stress Resistant Components & Enclosure Stress Resistant Components & Enclosure Miniaturized X-ray Tube Miniaturized X-ray Tube Si-PIN Diode Detector Si-PIN Diode Detector Patented Window Analysis Patented Window Analysis Developed by the Naval Research Lab (NRL) for soil profiling in remediation of superfund clean up sites. Under Cooperative Research and Development Agreement (CRADA) with NRL, inventor Dr. Tim Elam is partnered with Austin AI to further develop the probe for commercial applications. Markets Served: Environmental Monitoring/Remediation Environmental Monitoring/Remediation Mining/Exploration Mining/Exploration Agriculture Agriculture
