Biogas, Biomethane, Soil Gas, Odor

The measurement of odor is carried out according to the UNI EN 13725 standard, which involves determining the concentration of odor in a gaseous sample using dynamic olfactometry with a panel of examiners. The method is applicable to odor emissions from chimneys or area sources such as biofilters, purification tanks, or heaps.

We are present in Italy with two Accredia-accredited laboratories located in Casanova Lonati (PV) and Mesagne (BR).

In addition to odor measurement, we can perform the chemical characterization of odoriferous substances by air sampling using specific supports (canisters and vials). The analysis utilizes gas chromatographic systems with mass spectrometry combined with thermal desorption, as outlined in EPA TO-15A and EPA TO-17 standards. The versatility of canister sampling allows for monitoring durations ranging from 30 minutes to 48 hours. These activities comply with regional regulations on odor emissions and the ministerial decree approving the "Guidelines for the application of Article 272-bis of Legislative Decree 152/2006 on odor emissions from plants and activities," issued in June 2023.

LabAnalysis Environmental Science has over two decades of experience in odor measurement activities and the characterization of odoriferous substances. We combine dynamic olfactometry with a panel of examiners with the use of highly specialized analyses involving high-sensitivity instrumentation.

Within the specialized area dedicated to the soil gas matrix, LabAnalysis Environmental Science has a team of experts engaged in sampling for the monitoring of gases and vapors at contaminated sites using soil gas probes, such as nesty probes, installed in the ground. This can also involve the use of static dynamic flow chambers (flux chambers) in accordance with the reference SNPA guidelines.

Sampling is conducted using specific supports (vials, filters, thermal desorption vials, canisters, vacuum bottles), and the analyses employ state-of-the-art techniques available in the market to achieve threshold concentrations and quantification limits as outlined in the SNPA guidelines 15/2018.

The types of substances to be investigated can be customized and extended to site-specific pollutants, even those not covered by the guidelines.

LabAnalysis Environmental Science supports its clients in the verification and development of land remediation systems (soil vapor extraction, bioventing, multiphase extraction) by monitoring the concentrations of treated pollutants.

The laboratory monitors gas emissions from landfill surfaces according to the LFTGN07 Guideline "Guidance on monitoring landfill gas surface emissions" to identify critical points for investigation (walkover survey) and measure the emissive flow of pollutants from the landfill body (flux box survey) using accumulation chambers and specific analyzers for direct reading.

LabAnalysis Environmental Science can assist its clients in monitoring pollutants in landfill gas collection systems (gas spy, biogas wells).

Our laboratory is equipped with cutting-edge instrumentation, allowing operators to perform sampling with quality and safety, ensuring the representativeness of the results.
