Description:
A novel macroporous polymer material (Shodex) was evaluated as a stationary phase in liquid chromatography for the separation of a wide variety of aliphatic, oxygenates and polynuclear aromatic compounds using a variety of solvents. Fundamental studies were performed that determined the chromatographic properties of this new macroporous polymer packing. In addition to the evaluation of this stationary phase packing material, a reversed phase ion partition chromatography procedure was developed by which, through the use of methylene blue, a highly sensitive method for determining sub-microgram quantities of alcohols was developed. Analytical methods to measure the organic and total carbon content of ambient particulate matter collected on Teflon and quartz filters were also intercompared. Estimation of the soot or light absorbing carbon collected on Teflon and quartz filters by use of light absorption methods (light transmission and photoacoustic) compared favorably with the combustion procedure used to measure soot carbon.
