Sample conditioning

The term “sample conditioning” simply means the preparation of the gas sample containing your analyte to render it suitable for introduction into your gas analyzer. This is usually less of a consideration in ambient air monitoring applications than in source monitoring applications. When sampling from a source such as an industrial process, utility stack, or…

Recommendations on sample tubing

Back in the 1970s, many multi-point systems were being deployed, for monitoring carbon monoxide in parking garages and vehicular tunnels. Since long and otherwise exposed sample tubing runs needed to be installed, copper tubing was used. Because CO is not very reactive, and copper tubing is both flexible and robust, this was a preferred choice.…

Ethylene And Fruit Ripening

How about a little peak into the secret life of plants? Fruit ripening is a form of senescence and signifies the final stage in fruit development. Ripening, of course, eventually leads to spoilage, so there are important commercial reasons to increase and control post-harvest longevity. Complicating matters, post-harvest longevity varies naturally. Strawberries, for example, last…
