Interscan - Dilution System for Gas Detection Applications
The Dilution System [flow diagram] operates by mixing the sample to be analyzed (the analyte) with diluent purified air or nitrogen. The optimal flow rates for both the analyte and diluent are determined based on the particular application, and are monitored and controlled at integral rotameters.

Certain gas detection applications are better served if the sample is diluted before it reaches the analyzer. Sample dilution is used to:
- Make measurements beyond the nominal range of the analyzer
- Extend sensor life by reducing the concentration of gas directed to the sensor—especially in situations where a high background concentration is always present
- Dilution ratios available 3:1 to 1000:1 [Based on rotameter configuration]
- Dilution accuracy ± 10%
- Integral pump Diaphragm type, driven by vibrating armature
- Wetted surfaces Teflon, polypropylene, polyethylene/ethyl vinyl acetate
- Rotameters Glass tube, stainless steel valve, float material depends on application
