KRYPTONATE-BASED INSTRUMENT FOR DETECTING AUTOMOBILE- EXHAUST POLLUTANTS

THE TECHNICAL FEASIBILITY OF USING KRYPTON (KR) TO DETECT POLLUTANTS - CARBON MONOXIDE, NITROGEN OXIDES, AND HYDROCARBONS - IN AUTOMOBILE EXHAUSTS IN CONCENTRATIONS BELOW THE PROJECTED 1975 STANDARDS WAS DEMONSTRATED. IN A LABORATORY TEST SYSTEM, THESE WERE DETECTED BY A PLATINUM OXIDE KRYPTONATE SENSOR, A HYDRO-QUINONE CLATHRATE SENSOR, AND A PALLADIUM CHLORIDE KRYPTONATE SENSOR. NEW JERSEY HAS ALREADY ESTABLISHED STATE-RUN AUTOMOBILE INSPECTION STATIONS; PLANS EXIST TO EQUIP THESE LANES WITH INSTRUMENTS TO MEASURE AUTOMOBILE POLLUTANT LEVELS. NEW JERSEY APPEARS TO BE SET ON THE INFRARED AND FLAME IONIZATION TECHNIQUES FOR DETERMINING CARBON MONOXIDE AND HYDROCARBONS, RESPECTIVELY, DESPITE THE COST AND COMPLEXITY. SUITABLE INSTRUMENTS FOR MEASURING NITROGEN OXIDES ARE NOT AVAILABLE, AND NEW JERSEY IS VERY MUCH INTERESTED IN THE KR TECHNIQUE FOR THIS MEASUREMENT. ONCE INSPECTION HAS BEEN INSTITUTED, COMPARATIVELY CHEAP INSTRUMENTS MUST BE AVAILABLE FOR GARAGES SO THAT SATISFACTORY REPAIRS AND ADJUSTMENTS CAN BE MADE. THE KRYPTONATE TECNIQUE WAS THOUGHT TO BE VERY PROMISING FOR THIS REQUIREMENT. /AUTHOR/
