Easy-VOC
™
Simple, catch-all sampling solution for VOCs in air or gas Vapour-phase organics such as ambient air toxics, soil gas contaminants or fugitive industrial emissions can be monitored using a variety of techniques and sampling media. Bags, canisters, sorbent tubes and passive samplers have all been used for many years. Each air sampling option has its own inherent advantages and disadvantages. In challenging field conditions sometimes the simplest grab-sampling methods are the most suitable. Grab-sampling involves collecting volumes of air or gas instantly or over a very short period of time, without pumps or complicated mass flow control equipment.
Product highlights • Easy grab-sampling onto sorbent tubes. • Robust and intuitive, with no pump to calibrate. • 50–500 mL volumes. • More versatile alternative to canister sampling – compatible with n-C3 to n-C32. • Accommodates ¼″ and 6 mm o.d. sorbent tubes.
Originally, grab-sampling was only possible using canisters, but canisters are a cumbersome and expensive monitoring option and are only compatible with compounds over a limited volatility range (typically C2 to n-C8/9). Sorbent tubes are compatible with a much wider range of compounds including volatiles from C3, semi-volatiles to n-C32 and above (including phthalates, PAHs and PCBs), plus many polar and reactive species.
Accurate & reproducible sampling volumes Easy-VOC facilitates the rapid, grab-sampling of small volumes (1 ppb when using quadrupole MS detectors.
