Gas-chromatographic method ICS 65.160 X87 National Standards of People's Republic of China Determination of total particulate matter in cigarette nicotine Gas chromatography (ISO 10315.2000, MOD) Posted 2009-03-26 2009-06-01 implementation Administration of Quality Supervision, Inspection and Quarantine of People's Republic of China Standardization Administration of China released ForewordThis revised standard adopts ISO 10315.2000 "nicotine cigarette smoke condensate by gas chromatography" (in English). This standard is based on ISO 10315.2000 redrafted. Taking into account the situation of our country, the present standard and ISO 10315.2000 the presence of a small amount of technical differences compared to the relevant technical differences have been incorporated into positive The paper and the terms they covered the margin identified by a single vertical line. It is given in Appendix B of these technical differences and their reasons List for reference. For ease of use, this standard ISO 10315.2000 made the following editorial changes. --- Remove ISO 10315.2000 Foreword; --- Remove ISO 10315.2000 Introduction; --- Remove ISO 10315.2000 references; --- Increase in Appendix B "of the present method and ISO 10315.2000 of control."

In purity was determined to meet the requirements and do not smoke while eluting with the other components of the case, carvone, n-octadecane, or other substances may also be Used as internal standard. Each sample should be monitored when the measured peak area of \u200b\u200bthe internal standard remain unchanged, if the change should be used without the internal standard samples extracted Was taken to verify, confirm sample liquid component not including the peak elution position of standard substance (see Chapter 9). Containing the appropriate concentration of isopropanol in the standard (4.4) of (4.3), generally 0.2mg/mL ~ 0.5mg/mL. 4.5 extraction agent. If the extraction agent No temperature control during storage prior to use should be balanced to (22 ± 2) ℃. 4.6 Standard substance. according to GB/T 23225 verification of known purity nicotine, at 0 ℃ ~ 4 ℃ stored. It may also be used in accordance with the GB/T 23225 verification of known purity nicotine salicylate salts. 4.7 Standard solution. nicotine standard substance (4.6) dissolved in extracting agent (4.5), the standard solution was prepared at least 4, at a concentration range should cover Cover anticipated detected in a sample of nicotine concentration (generally 0.02mg/mL ~ 2.0mg/mL). Standard solution should be avoided at 0 ℃ ~ 4 ℃ Light save. Cryopreservation extractant solution before use and should be equilibrated to (22 ± 2) ℃. ......Tips & Frequently Asked Questions:Question 1: How long will the true-PDF of GB/T 23355-2009_English be delivered?Answer: Upon your order, we will start to translate GB/T 23355-2009_English as soon as possible, and keep you informed of the progress.
