The transport of liquid gas samples must be carried out in pressure containers specially suited for this purpose, which may only be filled to a maximum of 80 %. If you do not have your own pressure containers available, containers with 150 ml (max. 200 bar) can be borrowed from us for a rental and cleaning fee. We can arrange the transport of these empty pressure containers to the customer, whereas the transport of the filled gas cylinders to us must always be organised by the customer for legal reasons.
If you do not wish to carry out the sampling yourself, we can offer sampling according to DIN EN ISO 4257 by trained personnel, if desired also directly at a petrol station. In this case, the samples can be transported in our special vehicle in compliance with all regulations.
Since the analysis of liquid gas samples raises a number of detailed questions, from sampling to transport to measurement on the equipment, we recommend contacting us when you are planning a gas measurement. In this conversation, all important details such as sample vessels, connections, pressure ratios, duration of transport, etc. can be discussed in detail so that the incoming samples can be measured immediately.

We have been accredited for the analysis of fuels since 1998.
The flexible accreditation allows the application of accredited test procedures with different dates of publication. Therefore, it may happen that an (outdated) version listed in the official annex to the accreditation certificate D-PL-11334-01-00 is no longer used in the ASG laboratory.
