Selective Retention of some Smoke Condensate Components: Phenols, Polyphenols, Heterocyclic N-Compounds - Die selektive Retention bestimmter chemischer Bestandteile des Kondensates: Phenole, Polyphenole, heterocyclische Stickstoffverbindungen

The authors present the basic analytical values for, and the calculation of CORESTA efficiency indices E_i related to some chemical items (phenols, polyphenols, Ehrlich-positive compounds, hetero-N compounds, indole) in the smoke of filter cigarettes (dark air cured type, two types of filter tips of the acetate group, with and without activated carbon additive). The calculation presented for proposed "selectivity indices" E_i / E_G confirms factually the high grade of selectivity for phenols and some hetero-N compounds in the experimented systems; some critical facts are called to the attention concerning the role played by the activated carbon additive
