Catalytic Combustion Detector (CCD)

Hydrocarbon and hydrogen selective Detects down to 500ppm Gas-less operating capability Inexpensive Built-in spare element About as sensitive as a TCD, the Catalytic Combustion Detector has the hydrocarbon selectivity of an FID, plus the ability to operate on air alone which is supplied by the  internal "whisper quiet" air compressor. The CCD detector can also be used as a hydrocarbon monitor in non-chromatographic applications where the CCD senses the total hydrocarbon content of a flowing air stream, or as a hydrogen/hydrocarbon leak detector. The CCD sensor, shown above, is rugged and can be expected to last a long time. A second sensor is included in the detector housing at no extra cost, providing a built-in replacement should the first sensor become inoperable. Replacement sensor sets install in minutes without tools and are very economical, making this detector a good choice for academic settings where the sensors may be damaged by inexperienced operators.
