| Abstract |
The application of chemical ionization mass spectrometry to the instrumental analysis of oxygenates in automobile exhaust gases is described. Initial monitoring experiments demonstrated the capability of this technique to simultaneously measure the instataneous concentration of formaldehyde, acetaldehyde, acrolein, propionaldehyde, crotonaldehyde, butyraldehyde, valeraldehyde, and benzaldehyde, and the total aldehyde concentrations. Preliminary field evaluation established the accuracy and reliability of the instrument via suitable reference tests. An improved calibration procedure and inlet system were developed. These advancements resulted in a reduction of sample losses in the inlet system and an increase in the accuracy of the instrument. (Author) |
