Gaseous Samples

We analyse gas samples that were taken primarily by the employees of our company. Sampling is done in respect to the nature of the sample (direct sampling of gas sample, catchment of dust particles, sorption on solid sorbent or solution, reactive catchment etc.)

Common samples:

  • emission and imission
  • inner air or air of working place
  • soil air including landfill gas
  • biogas and other technical gases
  • pressured air


1. Emission and imission

  • Determination of content of solid polutants, i.e. dust fallout (followed by solid particles analysis with focus on heavy metal content or presence of persistant organic compounds)
  • Determination of inorganic contaminants after a catchment onto an absorptive solution (ammonia, sulphur oxides and sulphuric acid, nitrogen oxides, chlorine and inorganic chlorine compounds, Inorganic compounds of fluorine, mineral acids and bases, cyanides, sulphan, phosphin etc.)
  • determination of organic contaminants after catchment onto an absorbtive solution (fenols)
  • determination of organic contaminants after catchment onto a solid sorbent (common volatile organic compounds - see the attachment of the certificate of accreditation)
  • determination of organic contaminants after reactive catchment (carbonyl compounds, isocyanates)
  • asbestos determination (optical microscopy, electron microscopy)

2. Air in working environment

  • dust determination (fraction PM10, PM2,5, subsequent analysis of dust particles with focus on heavy metal content or presence of persistant organic compounds, identification a determination of asbestos filaments)
  • determination of solid aerosols (subsequent analysis with focus on heavy metal content)
  • determination of inorganic contaminants (see emissions and imissions)
  • determination of organic contaminants (see emissions and imissions)
  • determination of vulcanizing fumes
  • determination of microbial contamination (molds, bacterium Legionella Pneumophilla – sampling by aeroscope)

3. Soil air including landfill gas

  • determination of methane and carbon dioxide content (directly in gaseous sample)
  • determination of sulphur compounds and chlorine content (gaseous sample is analysed in laboratory)

4. Biogas and other technical gases

  • mostly determination of methane and carbon dioxide content (biogas, energy gases – possible determination of calorific value)
  • verification of purity of technical gases (e.g. cyanogen)

5. Pressured air

  • verification of purity of pressured air (solid particles content, humidity, contamination with oil residues)
