CORESTA Meeting, Smoke/Technology, Innsbruck, 1999, ST01

Analytical approaches for the determination of tobacco alkaloids

YANG S.S.; SMETENA I.

Philip Morris USA, Richmond, VA, USA

Tobacco alkaloids of interest include nicotine, nornicotine, myosmine, anabasine and anatabine. In the past, several analytical approaches were tested for the analysis of these compounds, involving the use of HPLC, capillary electrophoresis, and GC or GC ...

Determination of alkaloids in tobacco using solid-phase microextraction and GC

YANG S.S.; SMETENA I.

Philip Morris USA, Research Center, Richmond, VA, USA

This work is to evaluate the potential use of solid-phase microextraction (SPME) in the analysis of tobacco components, mainly alkaloids. In SPME, sampling can be done either by taking vapor phase in the headspace of a tobacco sample or by dipping the ...

Evaluation of fast gas chromatography for the analysis of tobacco components

YANG S.S.; SMETENA I.

Philip Morris USA, Research Center, Richmond, VA, USA

Combining experimental skills and novel technologies, gas chromatographic analyses of tobacco can be shortened from 30-60 minutes to several minutes. The dramatic increase in separation speed is achieved with little or no cost in the separation quality. ...

Evaluation of micellar electrokinetic capillary chromatography for the analysis of tobacco alkaloids

YANG S.S.; SMETENA I.

Philip Morris USA, Research Center, Richmond, VA, USA

It has been demonstrated that capillary zone electrophoresis (CZE) can be used for the determination of nicotine in tobacco. Under certain circumstances, nicotine analyses can be accomplished within a time period as short as 100 seconds. Simultaneous ...

Determination of small ionic compounds in tobacco and related materials by capillary electrophoresis

YANG S.S.; SMETENA I.

Philip Morris USA, Richmond, VA, USA

The separation and quantitation of organic compounds such as alkaloids and short-chain organic acids often encounter some difficulties due to their ionic characteristics. For example, two common problems in nicotine analysis, the adsorption in the liner ...
