KRYPTONATE-BASED INSTRUMENTATION DEVELOPMENT FOR AUTOMOBILE EXHAUST POLLUTANTS

摘要

This phase of the program encompassed the design, construction and evaluation of four (4) prototype instruments for the detection of auto mobile exhaust pollutant detection. These instruments employed the radio release mechanism utilized by Panametrics in detection of various trace gases.nhe prototype instruments were of two (2) designs. One design was operable from a power source supplied by an automobile battery. The second design was operable from 110 volts AC power.nSuccessful evaluation in the laboratory as well as with various automobiles were performed with both type instruments. Scale-up of the quantity of sensor material prepared introduced unexpected problems with respect to detection lifetime which were not satisfactorily resolved within the time and funds available to the program. Nevertheless, a Kryptonate based instrument using a single detection method for the measurement of hydrocarbons, CO and NO as pollutants by automobile exhausts was shown to be operable with actual automobile exhausts, to provide more than adequate sensitivity for inspection purposes, and to provide response and recovery times for full scale reading in the range 10-15 sees.
