Gas and biogas analysis:
Check the composition of your samples
Detect traces, measure purity, and comply with standards with precise and actionable analyses.
From safety to industrial performance, Quad-lab supports you in understanding, controlling, and optimizing your gases, regardless of the sector.
Our gas analysis fields
Analysis of gas matrices
At Quad-lab, we define gaseous matrices as any sample in the gaseous state collected at room temperature, without transformation, in suitable containers: bags, bulbs.
Biogas analysis in the laboratory
Independent laboratory specialized in the analysis of biogas and biomethane. We support operators, engineering firms, and project owners by providing reliable analyses tailored to the requirements of engine manufacturers and injection network managers.
The operation of a gas analysis
🧪 Sampling :
Sampling can be performed using various techniques, such as passive or active sampling (active sampling requires the use of a pumping system to ensure active circulation).
⚙️ Sample preparation :
After sampling, the gas sample must be prepared for analysis.
🔬 Analysis :
Gas analysis can be performed using various methods, such as gas chromatography (GC), infrared spectroscopy (IR), or mass spectrometry (MS). Each method has its advantages and can be selected based on the sample to be examined.
📈 Interpretation of the results :
Following the analysis, the results must be interpreted to identify the composition of the gas mixture and the various concentrations. One can juxtapose the results with established references or thresholds, for example, to assess air quality or compliance with regulatory standards.
Gas sampling supports
Not all sampling equipment is suitable for all types of gases.
Quad-Lab laboratory has tested the preservation of gases in different containers.
Contact us to select the most suitable option. The samples are taken very well on aluminized bags and sulfinert cylinders.
