SRA develops automatic line selectors for sequential sampling of multiple collection points or for automatic calibration. The selectors are compatible with systems based on μGC and PGC 3000 series industrial analyzers, developed directly by SRA in ATEX or rack versions. The selector and the analysis sequence programming and control are handled by the software Soprane.

The selectors may incorporate:

• Fast and slow-loop circuits with rotameters
• Filtering systems 
• Heating
• Pressure reducers
• Vaporizer and pump or suction ejector for lines at atmospheric pressure
