Amplified Geochemical Imaging, LLC has teamed with American Geological Services to market a passive soil vapor survey that will detect organic, inorganic and organometal(loid) vapors from buried ore deposits. The AGI Passive Sampler (AGI Module) allows for the direct detection of organic, organometal(loid) and inorganic compounds at the surface through hundreds of feet of post mineralization cover. Until now, surface geochemistry for buried mineral deposits has utilized indirect methods of detection. The AGI Passive Sampler makes the difference by allowing direct detection. The patented sample collector keeps water out while allowing vapors to pass through. The module captures organic, inorganic, and sulfur gases from buried mineralized systems. We achieve a high level of sensitivity from this technology with the combination of some unique elements: AGI’s patented expanded polytetrafluoroethylene (ePTFE) tubing • protects sorbents from soil and liquid water, ensuring sample integrity while allowing for the detection of a broad range of gases • waterproof and vapor permeable, allows for installation in low permeability and/or saturated settings Highly durable collector design • makes installation and retrieval simple, with no need to case the hole Engineered sorbent system designed for subsurface detection of gases • provides consistent sampling media and eliminates variability Mineral Exploration

Amplified Geochemical Imaging, LLC has
teamed with American Geological Services to
market a passive soil vapor survey that will
detect organic, inorganic and organometal(loid)
vapors from buried ore deposits. The AGI
Passive Sampler (AGI Module) allows for the
direct detection of organic, organometal(loid)
and inorganic compounds at the surface
through hundreds of feet of post mineralization
cover.
Until now, surface geochemistry for buried
mineral deposits has utilized indirect methods
of detection. The AGI Passive Sampler makes
the difference by allowing direct detection. The
patented sample collector keeps water out
while allowing vapors to pass through. The
module captures organic, inorganic, and sulfur
gases from buried mineralized systems. We
achieve a high level of sensitivity from this
technology with the combination of some
unique elements:
AGI’s patented expanded
polytetrafluoroethylene (ePTFE) tubing
• protects sorbents from soil and liquid water,
ensuring sample integrity while allowing for
the detection of a broad range of gases
• waterproof and vapor permeable, allows for
installation in low permeability and/or
saturated settings
Highly durable collector design
• makes installation and retrieval simple, with
no need to case the hole
Engineered sorbent system designed for
subsurface detection of gases
• provides consistent sampling media and
eliminates variability
Mineral Exploration
Gas chromatography/mass spectroscopy
(GC/MS) and gas chromatography/atomic
emission detection (GC/AED) analysis
yields sensitive, compound-specific results
that are used in identifying sources of
mineralization:
• About 90 compounds - through C20
• Aliphatics
• Aromatics
• Oxygenated compounds
• Inorganic and sulfur compounds
• H2S Hydrogen Sulfide
• S8 Molecular Sulfur
• (CH3)2S Dimethylsulfide
• CS2 Carbon disulfide
• COS Carbonal sulfide
• SO2 Sulfur dioxide
• MercuryText

Geochemical modeling and interpretation
differentiates vapor signatures from oxidizing
mineralization from those associated with
vegetation, host rock, or shallow pollution
Time-integrated sampling
• eliminates impacts caused by variations in
soil permeability or moisture; maximizes
sensitivity to a broad range (up to C20) of
hydrocarbons and sulfur compounds
Coding of each collector and container
• ensures high Quality Assurance/Quality
