CORESTA Meeting, Smoke/Technology, Xian, 2001, IG 02 (adjourned)

A global tobacco identity preservation program - TIPP

RYAN L.; GADANI F.; ZUBER J.; ROSSI L.; ARCHIBALD C.; FISHER C.

Philip Morris International Operations, Lausanne, Switzerland

The tobacco industry maintains the identity of tobacco types (sun, air or flue-cured) and grades in order to blend these components into the products preferred by our consumers. With TIPP this existing system was further developed to ensure...

A novel approach for the analysis of crop protection agents in tobacco

HAIB J.; HOFER I.; RENAUD J.M.

Philip Morris Europe, R&D, Neuchatel, Switzerland.

A new method has been developed for the analysis of crop protection agents (CPAs) in tobacco. The objective was to significantly increase the number of samples that can be processed by the laboratory and to make possible the extension of the method...

Formation mechanisms of PAHs for the low temperature pyrolysis of cellulosic materials

HAJALIGOL M.; MCGRATH T.; CHAN G.

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

The formation and yields of PAHs from the pyrolysis of cellulosic materials over the temperature range of 300 to 650 °C were investigated. At a temperature of 300 °C, no detectable amounts of PAHs were observed from the pyrolysis of cellulose,...

Per puff PAH analysis of cigarette smoke

LI S.; BANYASZ J.L.; SHAFER K.H.

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

A per-puff PAH analysis technique was developed in our lab and applied to study PAH formation and distribution in the smoking process. An impaction trap was used to collect the total particulate matter (TPM) from a single puff of smoke. The TPM was...

Isotopic labeling to elucidate carbohydrate pyrolysis mechanisms

PAINE III J.B.; NAWORAL J.; THOMAS C.E.

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

The flash pyrolysis of all six; of alpha-D-glucose, followed by GC/MS analysis, was used to determine the location from within the sugar molecule that the various product fragments arose. Most of the products arose intramolecularly: isotopically...

Formaldehyde in the gas phase of mainstream cigarette smoke

LI S.; BANYASZ J.L.; PARRISH M.E.; LYONS-HART J.; SHAFER K.H.

Philip Morris USA, RD&E, Richmond, VA, USA

Factors affecting formaldehyde deliveries in the gas phase of the mainstream smoke of a single puff were studied using Fourier transform infrared (FTIR) spectroscopy. The lighting puff (first puff), which generates significantly more formaldehyde...

The mechanisms of CO formation and reduction under smoldering conditions

HAJALIGOL M.; LI P.; ROSTAMI A.; YADAV R.; YI S.

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

Carbon monoxide is a product of tobacco pyrolysis and combustion which occur in a burning cigarette. Previous studies have characterized the major formation pathways of carbon monoxide as the pyrolysis of tobacco, combustion of tobacco char and...

A mathematical model of cigarette smoldering process

CHEN P.

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

A mathematical model for a smoldering cigarette has been proposed. In the analysis of the cigarette combustion and pyrolysis processes, a receding burning front is defined, which has a constant temperature (~450 °C) and divides the cigarette into two...

Characterization of the heat transfer for cigarette ignition propensity substrates using transient thermal analysis

WATKINS M.L.; JONES J.S.

Philip Morris USA, Richmond, VA, USA

This study describes the application of transient thermal analysis to study the diffusion of heat within materials commonly used to assess the ignition propensity of cigarettes. The propensity of cigarettes to ignite upholstered furnishings is...

The thermal performance of banded paper cigarettes

WATKINS M.L.; LYONS-HART J.L.; MURTHI R.M.V.

Philip Morris USA, Richmond, VA, USA

This talk describes preliminary investigations characterizing the differences in the thermal smoldering behavior of banded and non-banded cigarettes. Both free smolder and smolder during contact with combustible substrates will be described. The...
