Tobacco and tobacco products; Determination of alkaloid retention by filters of cigarettes
Описание (англ.):
Covers two methods for determining this effect, i.e. the direct method and the indirect method. Both of them are applicable to filter cigarettes, but generally the direct method is used. The indirect method shall be used only if the direct method cannot be applied because of incomplete recovery of the retained alkaloids from the filter material. The indirect method is not applicable to cigarettes with perforated or porousfilter tipping wraps.
