Determination of Small Molecular Aldehydes in Cigarette Smoke by Extraction and Derivatization in Single Drop

Abstract

Extraction and derivatization in single drop (EDSD) coupled to matrix-assisted laser desorp- tion/ionization Fourier transform ion cyclotron resonance mass spectrometry (MALDI-FTICR-MS) was utilized to determine small molecular aldehydes in single puff smoke. Through employing Girard's reagent T as derivatization reagent, small molecular aldehydes (SMAs) transformed into quaternary ammonium salt, and the sensitivity of analysis for SMAs was significantly improved. Using this method, acetaldehyde and acrolein in single puff smoke were easily determined. This approach with an automatic potential provided a simple, rapid, and accurate procedure for the determination of SMAs in smoke.
