Abstract
A normal-phase Bondapak high performance liquid chromatographic (HPLC) system was compared to two different reversed-phase Bondapak C18 systems for separating and quantifying aldehydes and ketones. In the normal-phase system, isocratic elution with 2-propanol (IPA) and hexane produced the best results. One reversed-phase system consisted of two C18 columns in series. The other reversed-phase system consisted of a single radial compression cartridge (RCC). Both reversed-phase systems employed solvent programming with acetonitrile/water as the mobile phase. Ultraviolet (UV) detection at 340 nm was used in all of the systems. Overall, the dual column reversed-phase system was found to be the most satisfactory, where precise measurements in the 0.05 to 10 ppm range were made for the low molecular weight carbonyls found in diesel exhaust. These carbonyls included the low molecular weight ketones, the C1–C6 aliphatic aldehydes, and two aromatic aldehydes.This publication has 0 references indexed in Scilit:
