Quasi-Simultaneous and Automated Measurement of Primary Amines and Short-Chain Aldehydes Emission by Dynamic SPME On-Fiber Derivatization Coupled With a Flow-Cell

An automated method was developed to simultaneously measure primary amines and short-chain aldehydes emission from foam and rubber samples in one experiment. The technique involved dynamic solid-phase microextraction (SPME) on-fiber derivatization coupled with a flow-cell unit. The parameters of the dynamic SPME on-fiber derivatization method were optimized, including SPME coating, derivatization agents loading temperature, loading time, and dynamic SPME extraction time. The linearity range for the four primary amines and three aldehydes ranged from 0.5 to 100 µg/m³ and 0.9 to 1050 µg/m³, respectively. The amines and aldehydes' quantitation limits (LOQ) were determined as 0.22-0.27 µg/m³ and 0.10-0.18 µg/m³, respectively. Compared to previous methods, this approach is efficient, labor-saving, and allows researchers to concurrently analyze the emission trends of aldehydes and amines in one experiment.
