No. 83 - Determination of Ammonia in Mainstream Cigarette Smoke by Ion Chromatography
(CRM developed into ISO 23919; ISO 23920)
This Recommended Method is applicable to the determination of ammonia in mainstream cigarette smoke as the ammonium ion, using IC with conductivity or suppressed conductivity detection. The method includes both sample collection techniques, separation and detection conditions. It additionally provides recommendations to laboratories regarding features that need to be controlled to provide data as robust and consistent as the repeatability and reproducibility data indicated. The method is not applicable for determination of ammonia in mainstream smoke generated from dark air-cured cigarettes.
