Stack gas sampling system

The SEC sampling system uses the Cold Dry Extractive method (Dry Basis Analysis).

• Sampling probe equipped with double stage particulate filtration
• Direct span gas injection for a complete system calibration
• Permeation-based drying system avoids loss of highly condensible gases (e.g. HCl, SO₂,NO₂ and HF)
• Automatic & periodic back-purge functionality for longer maintenance intervals
• Clean & dry sample transferred via unheated line (up to 100m distance) at ambient air temperature
• Large selection of probes available (depending on process conditions: stack diameter, gas temperature, water content, particulate concentration)
• Heated probe with choice of materials & lengths

Cold Dry Extractive (Dry Basis Analysis)
The gas sample is extracted and conditioned before transport, in order to have all moisture and condensible components removed prior to its analysis. Upon arrival
to the analyzer, the sample is clean, dry, at ambient temperature & water interference-free.
