Equipment & Sampling Media

Everything our field professionals arrive with — and everything the results will document.

Equipment & Media
Surface Wipe Kits Walls, ceilings, electronics, HVAC registers — direct surface particle collection
Bulk Sample Containers Insulation, drywall, ceiling tile, furniture residue — PLM/TEM examination
Airborne Filter Cassettes Personal air samplers and area monitors
Settled Dust Collection Media Personal property, ventilation ductwork, building surfaces
Chain-of-Custody Form Full COC from collection to PLM/TEM lab, ASTM D6602/D3849 compliant
What We Detect & Document
Soot vs. pre-existing dust PLM morphology confirms combustion-generated vs. background
Carbon black vs. fire soot TEM nanoscale ID critical for insurance disputes
Char & ash residue mapping Char indicates direct combustion; ash identifies fuel type
HVAC & infiltration extent Surface wipe mapping quantifies spread through ventilation
Particle origin tracing Provenance by morphology & element maps
Pre- vs. post-remediation comparison Clearance sampling confirms return to baseline

Common Situations That Trigger a Sampling Call

If any of these describe your situation — you need sampling, not guesswork.

Insurance claim

Scope of damage in dispute, adjuster needs defensible particle ID to substantiate or limit the claim.

Restoration contractor

Document contamination extent before work begins — baseline sampling protects scope and liability.

Post-fire re-occupancy

Air and surface sampling confirms safe soot levels before residents or workers return to the space.

Dark residue — fire or something else?

PLM confirms combustion-generated soot vs. mold vs. background dust — critical before any remediation decision.

HVAC system

Smoke infiltration mapping from adjacent unit fire — wipe sampling quantifies spread through shared ductwork.

Litigation or subrogation support

Chain-of-custody ASTM-compliant report for legal proceedings — defensible, court-ready documentation.
