• Definition of the installation as a function of the purity of the gas and the critical impurities for your analysis or process 
Our certified installation teams follow procedures defined especially for analysis :
Selection of tubing (material, quality, diameter)
Compatibility of the gases and materials
Airtight connections or fittings
For tube fittings and depending upon the gases used, our installations employ: double-ring connectors, connectors screwed to flat Kel-F joints, VCR connectors to metallic joints or butt-welded connections.
• Purging
By using successive purges to provide superior decontamination of the classical pollutants (moisture, air).
• Maintenance of installations
We hand over the installation in real use conditions.
• These steps are illustrated in a dedicated publication: gas network installation and gas handling.
