In air and soil gas investigations, achieving accurate, defensible results starts in the field. While TO-15 (whole-air canisters) and TO-17 (sorbent tubes) are well established, selecting and executing the right approach remains a challenge.
Hybrid SS® is designed to solve that problem.
What Hybrid SS® Is
Hybrid SS® is a sorbent-based sampling system analyzed by GC/MS using TO-17 methodology, with controlled air volume (syringe or pump) to collect VOCs onto sorbent media.
It is not TO-15 but complements it.
How It Fits with TO-15
• TO-15 = whole-air, fixed volume
• Hybrid SS® = sorbent, variable volume
Hybrid SS® bridges the gap:
• Use TO-15 for whole-air characterization and regulatory-driven sampling
• Use Hybrid SS® for flexibility, rapid TAT, emergency response, and targeted soil gas sampling
Why It Matters in the Field
• Adjust sample volume → control detection limits
• Rapid deployment in gridded work plans
• Pair with PIDs for confirmation and decision-making
• Defensible sub-slab sampling with Vapor Pin®
Bottom Line
Hybrid SS® doesn’t replace; it adds, giving teams a practical, reliable tool to characterize sites with confidence.
