TSRC, Tob. Sci. Res. Conf., 2022, 75, abstr. 56 Determination of particle size distribution from e-vapour products using the Dekati eDiluter™ Pro and ELPI®+ system JOZA P.; RODRIGUEZ-LAFUENTE A.; BAZARGAN H. Labstat International, Kitchener, ON, Canada Particle size is an important factor in determining aerosol deposition in the lungs and the absorption of aerosol compounds. In this study, the eDiluter™ Pro was used to generate the aerosol from e-vapour products. Real-time particle size...
CORESTA Congress, Online, 2022, Smoke Science/Product Technology Groups, ST 73 Quantitative determination of 23 flavour compounds related to potential additives in tobacco products and regulatory reporting requirements RODRIGUEZ-LAFUENTE A.; BIERNACKA P.; JOZA P. Labstat international Inc., Kitchener, Ontario, Canada In 2018, the National Agency of Health Oversight in Brazil (ANVISA) set forth provisions for the reporting of 165 compounds in tobacco products, to address potential attractiveness or enhanced addictiveness of these products. The objective of this...
CORESTA Congress, Online, 2022, Smoke Science/Product Technology Groups, ST 74 Quantitative determination of 28 flavour compounds (lactones and pyrazines) related to potential additives in tobacco products RODRIGUEZ-LAFUENTE A.; DONISA C.; JOZA P. Labstat international Inc., Kitchener, Ontario, Canada Many regulatory bodies require or will require the quantification of various flavour components in tobacco products addressing potential attractiveness or enhanced addictiveness issues related to these products. The objective of this study was to...
TSRC, Tob. Sci. Res. Conf., 2021, 74, abstr. 46 Determination of 2-Chloro-1,3-propanediol (2-mcpd) and 3-Chloro-1,2-propanediol (3-MCPD) in emissions by gas chromatography-mass spectrometry (GC-MS) WANG Jiaming; RODRIGUEZ-LAFUENTE A.; JOZA P. Labstat International Inc., 262 Manitou Dr., Kitchener, Ontario, Canada Monochloropropanediol (MCPD) and glycidol are thermally generated toxicants found in refined vegetable oils and glycerin. The purpose of this study was to develop a method for the quantitation of 2-Chloro-1, 3-propanediol (2-MCPD) and...
CORESTA Meeting, Smoke Science/Product Technology, 2021, Online, ST 15 Determination of tobacco specific nitrosamines (TSNAs) in heated tobacco product (HTP) blend by accelerated solvent extraction (ASE) and LC-MS/MS analysis RODRIGUEZ-LAFUENTE A.; WANG Jiaming; JOZA P. Labstat international Inc., Kitchener, Ontario, Canada Some studies (Vuarnoz, 2015; Williams, 2015) have pointed to chemical binding between TSNA and the tobacco matrix that are not extracted using standard extraction procedures. This potential negative bias may cause inconsistencies in ‘mass balance’...
CORESTA Congress, Online, 2020, Smoke Science/Product Technology Groups, ST 05 Determination of glycidol in e-liquids and emissions from e-cigarettes WANG Jiaming; RODRIGUEZ-LAFUENTE A.; JOZA P. Labstat International Inc., Kitchener, Ontario, Canada The direct analysis of trace levels of glycidol from e-liquids and e-cigarette emissions by GC-MS, is confounded by its size and the limited number of specific ions available for quantification. It is also susceptible to artificial formation...
