The CORESTA Recommended Method No. 9 (CRM 9) “Determination of Nicotine in Cigarette Filters by Gas Chromatographic Analysis” was first issued in October 1989. Its field of application is the determination of nicotine retention of cigarette filters made from paper or cellulose acetate plasticized with triacetin or triethyleneglycol-diacetate (TEGDA). The applicability of this method to filters containing adsorbents or chemical additives was uncertain at the time of issue.

The Routine Analytical Chemistry (RAC) Sub-Group undertook a study to review and update CRM 9 to include recent advances in GC analysis techniques and r & R statistics and to extend the scope to include filters containing carbon.
