ULTRA Passive Samplers, for VOCs, Chromosorb 106 Overview

ULTRA Passive Sampler, for VOCs (volatile organic compounds) and semi-VOCs, Chromosorb 106, 285 mg in each compartment; designed to sample low ppb to ppt levels of VOCs, pk/5
Limited shelf-life: 30 days at < 39.2 F (4 C)

The ULTRA® Passive Sampler offers a choice of four sorbents for environmental air sampling. The ULTRA samples by diffusion and provides low ppb to ppt detection of compounds, including semi-volatile organic compounds (SVOCs). Use the ULTRA as an alternative to stainless steel canisters for green building certification, fenceline monitoring, product emissions, vapor intrusion, and near roadway, traffic, public health/asthma, and school zone studies.

Applications

Public health/asthma studies
Near roadway air quality studies
Volatiles from soil gas, biological sources, and water
Traffic studies
Fenceline monitoring
Monitoring pollution migration from industrial processes
Odor profiling in fragrance, food, and flavor industries
Product emissions
Emergency response to oil spills and leaks
Green Building certification
Vapor intrusion
School zone studies

*	MRL — minimum reporting level: These can vary with each laboratory; check with the laboratory.
•	Indoor — low velocity conditions (< 5 cm/sec)
†	Outdoor — 5 to 200 cm/sec, low air velocities, typically found in indoor air, result in lower uptake rates in passive samplers
