Determination of the amount of volatile organic compounds (VOC) released by solid or liquid samples. The measurement is performed by placing the investigated sample in a chamber, through which nitrogen is flushed. The nitrogen is led through an absorption cartridge, which traps the VOC compounds. Upon completion of the gas collection, the trapped VOCs are analyzed with thermal desorption-gas chromatography (TD-GC). The measurement can either be performed at ambient temperature, or the sampling chamber can be heated.

Quantification of CH₄ (methane), CO₂ (carbon dioxide), O₂ (oxygen), N₂ (nitrogen), H₂S (hydrogen sulfide), and H₂O (water) in natural- and biogas samples with gas chromatography. Additional possibilities to analyze siloxanes (hexamethylcyclotrisiloxane (D3), octamethylcyclotetrasiloxane (D4), decamethylcyclopentasiloxane (D5), hexamethyldisiloxane (L2), octamethyltrisiloxane (L3), decamethyltetrasiloxane (L4), dodecamethylpentasiloxane (L5), and trimethylsilanol (SiOH)) as well as ammonia (NH3, using IC). The base package includes the quantification of CH₄, CO₂, O₂, N₂, H₂S, and H₂O. Please contact Measurlabs experts to check other sample vessel suitability for the analysis.

Classic stable isotope analysis of carbon (13C) with isotope-ratio mass spectrometry (IRMS). The results are reported in the unit VPDB, ‰. The analysis is suitable for various sample materials. Please contact the Measurlabs expert for more detailed information on the analysis.

The biocompatibility of medical devices with breathing gas pathways is generally assessed according to ISO 18562 standards. Measurlabs offers tests according to this standard family, including the following: ISO 18562-2: Tests for emissions of particulate matter (PM), ISO 18562-3: Tests for emissions of volatile organic compounds (VOCs). Our experts are happy to help with any questions related to the tests and prepare a quote for you. Contact us with your testing needs through the form below, and we will get back to you shortly.

Determination of volatile organic compounds (VOC) in water using the GC-MS technique. The analysis determines the concentrations of 67 volatile compounds including BTEX, DIPE, ETBE, MTBE, TAEE, TAME, and TBA. The results of the analysis are reported in µg/l.

Determination of the amount of hydrogen fluoride (HF) in a gas sample. Testing is performed by pumping the gas through a gas trap, after which the content of the trap is analyzed. The required pump and gas trap will be delivered to the customer before sampling. The customer performs the sampling and returns the equipment, upon which the analysis is performed. The detection limit depends on the volume of the sampled gas. Please see the details below.

Determination of the hydrogen sulfide (H₂S) content of natural gas or biogas samples. Please contact Measurlabs experts to check the suitability of other sample vessels for the analysis.

Determination of inhalable and respirable dust fractions present in indoor air. The aerodynamic diameters of the inhalable and respirable dust particles are < 100 µm and < 4 µm, respectively. The price includes a sample collector and a sample pump, which are delivered to the customer for sampling. Results are reported as mg/m³. According to the Finnish Ministry of Social Affairs and Health's decree on Hazardous Concentrations (538/2018), the normative threshold value for inhalable dust is 10 mg/m3 on an eight-hour average concentration.

Quantification of siloxanes in biogas or natural gas samples with gas chromatography: Hexamethylcyclotrisiloxane (D3) LQ : 0,10 mg/Nm3, Octamethylcyclotetrasiloxane (D4) LQ : 0,20 mg/Nm3, Decamethylcyclopentasiloxane (D5) LQ : 0,15 mg/Nm3, Hexamethyldisiloxane (L2) LQ : 0,10 mg/Nm3, Octamethyltrisiloxane (L3) LQ : 0,10 mg/Nm3, Decamethyltetrasiloxane (L4) LQ : 0,10 mg/Nm3, Dodecamethylpentasiloxane (L5) LQ : 0,5 mg/Nm3, Trimethylsilanol (SiOH) LQ : 0,10 mg/Nm3.

Quantification of heating value, CH4, CO2, O2, N2, H2, and C2–C5 alkanes in natural gas and biogas samples with gas chromatography. The sample can be shipped in a gas bag or preferably in an adsorbent tube. Standard methods available: ASTM D1945, ASTM D1946, ASTM D3588. Please contact our experts to check the suitability of other sample vessels.

Determination of the biomass fraction of CO₂ emissions generated from mixed fuel incineration, as required by the EU Emissions Trading System (ETS). CO₂ originating from non-fossil sources like biomass has an emission factor of zero under EU ETS and is therefore not counted towards carbon emissions. This means that the biomass fraction of mixed fuels, such as municipal waste or solid recovered fuel (SRF), must be determined to calculate reportable emissions accurately. In this analysis, the proportion of biogenic carbon dioxide in total emitted CO₂ from the incineration process is measured using the radiocarbon (¹⁴C) method. The measurement is based on the ASTM D6866 standard. This standard is equally rigorous and based on the same methodology as EN ISO 13833, which is mentioned in Commission Implementing Regulation (EU) 2018/2066 on the monitoring and reporting of greenhouse gas emissions. Testing is relevant for industrial plants that use mixed fuels and participate in emissions trading, as well as for municipal waste incineration (MWI) plants, which have been required to monitor and report emissions according to EU ETS since the beginning of 2024.

Quantification of CH₄ (methane), CO₂ (carbon dioxide), O₂ (oxygen), N₂ (nitrogen), H₂ (hydrogen), H₂O (water), and C2-C5 alkanes in natural gas and biogas samples with gas chromatography. Please contact Measurlabs experts to check the sample vessel's suitability for the analysis.
