What is ISO 23920 about?
ISO 23920 is a standard that covers the ion chromatography test method for cigarette mainstream smoke with an intense smoking regime that enables accurate determination of ammonia in cigarettes and regulate its content.
ISO 23920 specifies a method for the quantification of ammonia by ion chromatography in mainstream smoke using ISO 20778 smoking parameters.
ISO 23920 specifies is applicable to an ammonia yield of about 10 μg/cigarette to 40 μg/cigarette.
Note: ISO 23920 does not apply to -
- Determination of ammonia in dark-air cured cigarettes
Who is ISO 23920 for?
ISO 23920 on determination of ammonia in cigarettes is applies to:
- Manufacturers of cigarettes
- Distributors and importers of cigarettes
- Testing houses and labs for cigarettes
- Government regulators
Why should you use ISO 23920?
Tobacco filler contains ammonia which is used as a chemical additive. Ammonia chemicals raise alkalinity, making nicotine easier to absorb into the body and increasing nicotine dependency and addiction in smokers.
ISO 23920 provides you guidance on the ion chromatography method that includes two alternative trapping systems which are, a combination of glass fibre filter pad followed by impinger traps and impregnated GFP followed by a GFP to accurately determine the ammonia content in cigarettes.
ISO 23920 method is based on the results obtained in a collaborative study that involved 18 laboratories and 8 samples using cigarettes manufactured from a range of blend styles that ensures the authenticity and accuracy of the test method for determining ammonia.
ISO 23920 ensures that you perform the method accurately by providing you with a step-by-step procedure for the method.
The guidance in ISO 23920 enables you to identify ammonia content in cigarettes to regulate its content and limit dependency and addiction in cigarettes.
