The report deals with the prototype aldehyde analyzer built by Scientific Research Instruments Corporation (SRIC). With the instrument, called the AUTOSPECT, SRIC has been able to simultaneously analyze engine exhaust for 9 different oxygenates. Although the AUTOSPECT can be calibrated to determine almost any desired oxygenate, the current instrument is set to determine the 9 most prevalent aldehydes believed to be present in exhaust gas. Work on the AUTOSPECT is aimed at procedural improvements and reductions to a practical portable oxygenate analyzer. In addition to unburned hydrocarbons, carbon monoxide, and oxides of nitrogen, the exhaust of automotive vehicles contains small amounts of partially combusted materials known as oxygenates. The most prevalent class of oxygenate components are known as aldehydes. Aldehydes are odoriferous, in some cases irritating to the eyes, and potential sources of photochemical reactions conducive to the formation of smog. (Author)
