Equipment & Sampling Media
Every tool required for a complete on-site VOC and IAQ investigation — from real-time screening to chain-of-custody lab samples.
Common Situations That Trigger a Sampling Call
If any of these describe your situation — you need sampling, not guesswork.
New flooring, paint, or renovations
Occupants reporting headaches, dizziness, or throat irritation after recent work.
Tenant or employee complaints
Recurring odor complaints or IAQ concerns in commercial or residential building.
School or daycare odor concern
Parent or staff complaint about chemical smell or health symptoms in occupied space.
Post-remediation clearance
Confirm VOC levels acceptable before re-occupancy after spill, fire, or chemical release.
Litigation or insurance support
Legal dispute over IAQ conditions — need defensible GC/MS documentation.
Unknown odor source
Smell with no identified cause — room-by-room PID mapping locates the zone.
Why VOC Testing Matters
VOCs off-gas continuously from common building materials, furnishings, and HVAC systems — often at levels that exceed health guidelines in occupied spaces.
Building Materials
- Flooring adhesives
- Paints & coatings
- Composite wood products
Furnishings & Finishes
- New furniture & carpet
- Upholstery treatments
- Cleaning products
HVAC & Infrastructure
- Duct linings & sealants
- Insulation off-gassing
- Combustion byproducts
The IRIS SentinelAir Pro™
Advanced PID-Based Real-Time VOC Field Screener
Photoionization detection delivers total VOC concentration in real time — no waiting for lab turnaround.
Field professionals log readings space by space to build a contamination map of the entire property.
Characteristic emission patterns help identify likely source materials on-site during the investigation.
Many cases are resolved at the screening level without requiring laboratory sample analysis.
Two Service Levels. One Streamlined Process.
Matched to your situation — from same-day screening to regulatory-grade compound identification.

VOC Index Scoring Table
How the VOC Index Score Works
Methodology · Baseline Control · Scoring Logic
The VOC Index is a normalized 0–500 score derived from real-time TVOC field readings collected by the SentinelAir Pro™ in mg/m³. Rather than presenting raw concentration values, the score translates measurements into a simple, actionable scale — making it easy to compare readings across rooms, floors, and building zones without requiring technical interpretation.
Every investigation begins with an outdoor air reading taken away from building entrances, exhaust vents, and traffic. This establishes the ambient background VOC level for that day and location — the baseline. Indoor readings are then interpreted relative to this control. An indoor score meaningfully above the outdoor baseline is a stronger indicator of an internal emission source than the absolute number alone.
If indoor scores remain near the outdoor baseline, no further action is typically warranted. When indoor readings exceed the baseline — particularly in specific zones — the score pattern guides source investigation. Scores in the Elevated or High range trigger Tedlar bag collection for laboratory GC/MS analysis to identify the specific compounds and concentrations present.
