AbstractA gas chromatographic method is described which is suitable for the quantitative routine determination of CO in tobacco smoke. The CO is separated from other gases on a moderately activated molecular sieve column and is quantitatively determined after hydrogenation on a nickel-contact at 290°C with a flame ionisation detector. The method is characterized by high sensitivity and great stability of the separation column. A comparison of a "constant flow" smoking machine and a smoking machine operated by pistons, in the course of which a container filled with a saturated solution of sodium chloride or a polyvinylchloride bag was employed for gas storing, led to comparable results. The addition of NaNO

Abstract Functionality distributions of telechelic prepolymers have been determined by thin layer chromatography (TLC). Commercially available 1,2-polybutadienes having either carboxyl or hydroxyl groups were examined. TLC with p-xylene as the developer made it possible to separate the sample into a nonfunctional component and a mixture of mono- and difunctional components. Complete separation of the sample into the three components was achieved by selecting the developer and development procedure appropriately. Quantification of the chromatograms was performed successfully in a TLC apparatus equipped with a flame ionisation detector. A simple method for the determination of the functionality distribution was proposed.
