2015 Collaborative Study on Ammonia in Mainstream Cigarette Smoke
SMA Technical Report
From 2013 to 2015 the CORESTA Special Analytes Sub-Group (SPA) (now named Smoke Analytes Sub-Group, SMA) evaluated analytical methods for quantitative measurement of ammonia in mainstream cigarette smoke using Ion Chromatography (IC) with conductivity or suppressed conductivity detection.
It was concluded that the two trapping systems were fit for purpose for cigarette products of various designs and constructions with ISO nicotine-free dry particulate matter (NFDPM, tar) in the range 1,3-14,2 mg/cigarette. The methods were determined not fit for purpose for measurement of ammonia in the mainstream cigarette smoke generated from dark air-cured samples.
A CORESTA Recommended Method (CRM 83) was subsequently drafted and published.
