Air Sampling Bottles Offer a More Cost-Effective Solution for Soil Gas Analysis
- Protective, foam-filled box prevents bottle breakage during sampling, transportation, and analysis.
- Easy-access, leak-tight RAVEqc valves prevent sample loss and are quick and simple to use.
- Inert, deactivated glass ensures reactive compounds are stable and can be accurately reported.
Stainless-steel air sampling canisters work well for ambient air testing, but for soil gas testing, air sampling bottles can save labs significant time and money. Because soil vapor is often highly contaminated, canisters are difficult and time-consuming to clean and can even become irreversibly contaminated. Glass air sampling bottles are a much less expensive alternative, but they can shatter, causing injury as well as the time and expense of resampling. Restek offers a better solution: our deactivated air sampling bottles are housed in specially designed, protective packaging that allows direct access to the valve while the bottle stays protected during sampling, transportation, and analysis.
Protected and disposable, Restek air sampling bottles are more cost-effective for soil vapor testing than air canisters.
Get Full Protection with an Easy Connection
At a fraction of the price of air canisters, Restek’s air sampling bottles are designed for ease of use and peace of mind. While the bottles may be used for indoor or ambient air sampling methods, such as Method TO-15A, they are ideal for soil gas and other highly contaminated samples. During use in the field and lab, the valve is easily accessed from a separate chamber while the bottle stays secure and protected within the box. In addition, the RAVEqc quick-connect valve makes it fast and simple for novices and experts alike to make consistent, leak-tight connections. After soil gas sampling and analysis, the bottles can either be cleaned and reused for additional savings or disposed of properly.
A separate chamber provides easy valve access while the bottle stays safe in the box, preventing breakage, sample loss, and injury.
Keep Active Compounds Stable for Accurate Reporting
While cost, bottle protection, and ease of use are critical, sample storage stability is also essential for accurate results. Stability testing proves that the deactivated glass air sampling bottle is highly inert, which prevents the breakdown of active analytes and ensures more accurate reporting. As shown in Table I, all compounds met the ±30% stability criteria in Method TO-15A after 30 days of storage. Deactivated valves are also available for a fully protected sample path.
Table I: Analyte concentration is stable over 30 days in air sampling bottles due to highly effective glass deactivation.
