Abstract
Abstract A reagent used for the analysis of total aldehyde concentrations, 1,3-cyclohexanedione, was adapted to the trace analysis of aldehydes using high-performance liquid chromatography. Experiments were performed to determine the optimal reagent composition, stability of the derivatives, reproducibility and reagent clean up. Many of the optimal reaction conditions with 1,3-cyclohexanedione were found to be very similar to those with an analogous reagent, dimedone. However, 1,3-cyclohexanedione has some advantages, namely that it is more soluble in water than dimedone, making reagent preparation easier, and the derivatization reaction occurs at a lower temperature. Removal of contaminants from the reagent is readily achieved with a method employing disposable cartridges of reversed-phase material. Applications to environmental samples are reported.
