Determination of carbon monoxide in the gas phase of cigarette smoke Non-scattered infrared method1 ScopeThis document describes a method for the non-dispersive infrared determination of carbon monoxide in the gas phase of cigarette smoke. This document applies to the determination of carbon monoxide in the gas phase of cigarette smoke. 2 Normative references The contents of the following documents constitute the essential clauses of this document through normative references in this document. For referenced documents without a date, only the version corresponding to that date applies to this document; for referenced documents without a date, the latest version (including all amendments) applies to This document. GB/T 16447 Atmospheric conditions for the conditioning and testing of tobacco and tobacco products (GB/T 16447-2004, ISO 3402.1999, IDT) GB/T 16450 Definitions and standard conditions for smoking machines for routine analysis (GB/T 16450-2004, ISO 3308.2000, MOD) GB/T 19609 Cigarettes - Determination of total particulate matter and tar using a smoking machine for routine analysis (GB/T 19609-2024, ISO 4387. 2019, MOD) 3 Terms and Definitions The following terms and definitions apply to this document. 3.1 vapor phase Use a smoking machine that complies with the requirements of GB/T 16450 and the smoke passing through the smoke collector during cigarette smoking according to GB/T 19609. part. 3.2 clearing puff Any puffing on a cigarette after it has been extinguished or removed from its holder. 4 Principles According to GB/T 19609, smoke cigarettes, collect the gas phase of cigarette smoke, and measure the carbon monoxide with a non-scattering infrared analyzer to calculate the carbon monoxide content of each cigarette. The amount of carbon monoxide in flue gas. 5 Reagents or materials Use nitrogen with a purity of not less than 99.999% during the validity period as the mixed gas for carbon monoxide standard gas. Non-scattering infrared analyzer Calibration should be performed using at least three standard gases with known concentrations and a relative error of less than 2%. The concentration range of the standard gases should cover the range of the expected detection. The carbon monoxide concentration should be adjusted to avoid extrapolation of the curve. Standard gases with carbon monoxide concentrations (volume fraction) of 1%, 3%, and 5% should be used. ......Tips & Frequently Asked Questions:Question 1: How long will the true-PDF of GB/T 23356-2024_English be delivered?Answer: Upon your order, we will start to translate GB/T 23356-2024_English as soon as possible, and keep you informed of the progress.
