Foreword

GB/T 23203 "Cigarettes - Determination of water in" is divided into two parts.

--- Part 1. gas chromatography;

--- Part 2. Karl Fischer method.

This is Part 1 GB/T 23203 of.

This section drafted in accordance with GB/T 1.1-2009 given rules.

This Part replaces GB/T 23203.1-2008 "Cigarettes determination of water - Part 1. gas chromatography", and GB/T 23203.1-2008 main technical changes compared as follows.

--- Gas Chromatography cigarette total particulate matter in the water increases the detection capillary columns.

This section uses redrafted Law Amendment uses ISO 10362-1:1999 Determination of "cigarette total particulate matter in the water - Part 1. Gas Phase chromatography "(in English), and this part of ISO 10362-1:1999, compared with more adjustment in the structure, listed in Appendix B of this section and ISO 10362-1. reg number control list 1999, this part of ISO 10362-1:1999 as compared to the presence of technical differences, these differences Terms have been involved in a single vertical line through the blank space in the outside margin was identified in Appendix C gives the corresponding technical differences its list of reasons.
