Investigation of the Effluents Produced during the Functioning of Black and White Colored Smoke Devices

摘要

The qualitative quantitative analyses on the combustion effluents from black and white colored smoke devices have been completed. Techniques for qualitative identification of the structures from combustion effluents were basically similar to that described in the previous paper. Quantitative analyses were completed by obtaining the smoke settling curve at first, Only the amount of smoke collected within the range of the smoke settling curve plateau was used to calculate the quantities of each combustion product. Quantification for most of the combustion effluents was accomplished by comparing the areas of HPLC and GC spectra with that of the standard compounds which are commercially available. Others were estimated by total ion counts or single ion monitoring methods using a mass spectrometer with or without internal standards.
