Formula: C5H6O2. So far, in addition to halogen atoms, other non-metallic atoms can become part of the aromatic heterocycle, and the target ring system is still aromatic. Compound: 5-Methylfuran-2(3H)-one, is researched, Molecular C5H6O2, CAS is 591-12-8, about Online analysis of aerosol components of heated tobacco products by GC-MS.
In order to study the chem. composition of aerosols from heated tobacco products (HTPs) and to investigate the puff-by-puff release characteristics of aerosols from HTP samples, an online sampling device for HTP aerosols was developed by adopting a valve injection technique. Using this technique, HTP aerosols were directly introduced into gas chromatog.-mass spectrometry (GC-MS) by carrier gas (helium) through an inline heating transmission line without sample loss. The results showed that the online HTP aerosol anal. system had a stable performance and good reproducibility. The contents of acetone and 2-butanone determined in the aerosols of sample A by this method was in good accordance with the results reported by literature. With the proceeding of puffing, the releases of acetone and 2-butanone from the aerosols of sample B increased first and then decreased. This method is simple, efficient and suitable for the online anal. of the whole aerosols of HTPs and the puff-by-puff release characteristics of HTP aerosols.
