Gas analytics

With sampling carried out by our specialists and express analysis immediately afterwards on our highly sensitive laboratory instruments, we deliver a fast and highly precise analytical result for a wide range of questions. Alternatively, you can send us gas samples taken by your own specialists.

In that case our service team is glad to provide sampling kits and transport boxes and to handle dispatch and collection for you. On request we also install sampling systems at your site for straightforward handling of the sampling process.

You receive our detailed result reports immediately after the analysis. Our experts are available to discuss the results and are glad to advise you.

We offer the following services:

• Determination of various trace components in hydrogen in accordance with SAE J2719, ISO 14687 and DIN EN 17124, as well as in natural gas, biogas, synthetic gases (SNG) and liquefied natural gas (LNG
• Sampling at natural gas and hydrogen refuelling stations, power plants, biogas plants and similar facilities
• Mobile measurement of hydrogen, methane slip and other exhaust trace components in the exhaust streams of plants

• Measurement and determination of trace components in biogas at biogas production plants, also in accordance with DVGW code of practice G 269
• Measurement and determination of the odorant content in distributed natural gas in accordance with DVGW code of practice G 280, and determination of sulphur components
• Determination of gas physical properties (density, calorific value, Wobbe index and others) in fuel gases (NG, SNG, biogas, LPG, LNG and others)
• Chemical and physical analytical support for performance tests during the installation or inspection of gas turbines, combined heat and power units and other gas combustion plants.

Our testing laboratory is accredited to DIN EN ISO/IEC 17025 by the DAkkS The accreditation covers exclusively the scope stated in the annex to the certificate.

Our mobile laboratory makes gas quality measurement of laboratory standard possible directly on site – for example at production facilities, during loading and unloading of tankers or during plant commissioning. The causes of any deviations from target values can be investigated immediately on site.

The innovative sampling system enables online measurement in virtually any application at pressures up to 1,000 bar. The sample can be taken directly at the filling coupling, with no need for a service employee of the customer or the manufacturer to be present.

As a testing laboratory accredited to DIN EN ISO/IEC 17025:2018, we work to the highest quality standards and international norms. In addition, we work to in-house methods that we have developed and validated ourselves.

The measurement technology installed in the vehicle has also been successfully validated with regard to the limit values under SAE J2719, ISO 14687 and DIN EN 17124, in cooperation with a specialty gas producer in Germany.

As hydrogen becomes established as an energy carrier, materials and auxiliary substances that come into contact with hydrogen under various conditions (pressure, temperature) must be tested for chemically and physically neutral behaviour. This applies in particular to seals, adhesives, lubricants and plastics. If impurities are released from these materials, sensitive components such as the membrane electrode assembly of the PEM fuel cell can be damaged or destroyed. Toxic substances such as hydrogen sulphide may also be formed.

Using the measuring chambers we have developed ourselves for analysing material compatibility, we can reveal undesirable reactions of hydrogen-wetted parts while varying pressure, temperature and flow.

This allows potential sources of hydrogen contamination to be identified in advance and ruled out through the targeted selection of suitable materials.

As one of only two officially approved certification bodies in Germany, we certify a broad spectrum of test and calibration gas mixtures:

• Determination of the certified amount-of-substance fractions by a high-precision gas chromatographic comparison measurement against a secondary standard certified by the Federal Institute for Materials Research and Testing (BAM)

• Quality assurance by means of a further secondary standard certified by BAM, together with a direct density measurement and additional gas chromatographic examinations
• The accuracy of the calculated standard density is ensured by a directly measuring method
• The majority of the calibration gas mixtures are certified for process gas chromatographs in accordance with PTB-A 7.63
