Air sampling bottles for cost-effective soil gas analysis
Ideal for soil vapour testing, air sampling bottles are more cost-effective for highly contaminated samples than air canisters. While other sampling bottles can easily break, Restek offers a better solution: air sampling bottles are housed in specially designed foam packaging that keeps the bottle protected during sampling, transportation, and analysis. A separate chamber provides easy access to the RAVEqc quick-connect valve, making it fast and simple for novices and experts alike to make consistent, leak-tight connections. These deactivated glass air sampling bottles are highly inert, which prevents the breakdown of active analytes and ensures more accurate reporting. Deactivated valves are also available for a fully protected sample path. In addition to soil gas testing, they can be used for indoor or ambient air sampling methods, such as Method TO-15A. At a fraction of the price of air canisters, Restek’s disposable air sampling bottles are designed for safety, ease of use, and peace of mind.

Continuous air quality monitoring for particulate matter and aerosols
When air pollution levels are high, it leads to illness. It also causes acid rain and harms wildlife. Since 99% of the population breath air which exceeds WHO’s quality guideline limits, this is a widespread issue. Among the various air pollutants, particle matter and aerosols are of particular concern.
It’s important to analyse the chemical composition of these pollutants to determine sources and long-term effects. By doing so, we can take steps to reduce emissions and work towards creating a healthier environment.
Metrohm Process Analytics is a well-known provider of analytical solutions for particle analysis. The company offers advanced instruments and software that gather accurate and reliable measurements of airborne particles.
The Metrohm AeRosol Sampler (MARS) samples aerosols, whilst the 2060 Monitor for AeRosols and Gases in ambient Air (MARGA) samples aerosols and water-soluble gases. Both instruments include gas denuders, condensation particle growth samplers, as well as, pumping and control devices.

The EPA test methods for evaluating solid waste (SW-846) provide a comprehensive source of information on sampling, sample preparation, analysis, and reporting. EPA 3546 was formally included in SW-846 and is a microwave assisted solvent extraction (MASE) procedure for extracting water insoluble or slightly water soluble organic compounds such as organochlorine pesticides, semivolatile organics, PAHs, PCBs, phenoxyacid herbicides, phenols, dioxins, and furans from soils, clays, sediments, sludges, and solid waste.
The above compounds were traditionally extracted using lengthy methods that required large volumes of solvents. MASE is a rapid sample preparation technique that enables efficient extractions but using reduced amounts of solvents with the ability of working at higher temperatures and pressures. For example, the Milestone Ethos X microwave extraction system from Analytix can extract the target compounds from environmental samples in full compliance with EPA 3546 (100-115 °C and 50-150 psi) and is capable of quickly processing up to 24 samples and 30 g of sample per vessel simultaneously thereby improving the limit of quantitation (LOQ) for analysis. This results in the capacity to extract over 200 samples in an 8-hour workday and the potential problems of contamination, memory effects, and cleaning are eliminated due to the use of disposable glass vials.
Twelve application reports highlighting the advantages of MASE for environmental samples are available from Analytix that demonstrate the recoveries of certified environmental standard materials being in compliance with the certificate values. In addition, it demonstrates that a wide range of different compounds can be completely extracted, even in large sample amounts.
The use of disposable glass vials coupled with speed of extraction and reduced solvent consumption makes the Ethos X a unique and innovative solution for the extraction of contaminants from environmental samples, providing unmatched ease of use and low running costs.
