System description:
Mixing chamber (injection chamber) to inject a known volume
of a component to generate a gas mixture with known concentration.
The process is the primary standard to generate gas mixtures
to calibrate gas analyzers. The development was for the most
part carried out by the National EU Clean Air Reference Lab,
a division of the Federal Environmental Agency, and is documented
in ISO 6144 as a standard.
The mixing chamber features sensors for the precise determination of the temperature and pressure. The values of the sensors can be directly imported to the laboratory information and management software IC-LIMS-2001 .
