本标准适用于卷烟烟气总粒相物中以上四种烟草特有亚硝胺的测定。

Introduction

Method highlights and technological evolution

This standard first proposed the combination of basic alumina chromatography column purification and GC-TEA coupling technology, which increased the sensitivity by 3 times compared with the 2000 version of the method. The International Tobacco Research Cooperation Group (ISO/TC126) included this method as a core reference.

Key technical nodes of the whole process

Steps	Parameters	Quality control points
Ultrasonic extraction	100ml×1+60ml×2	Recovery rate ≥92%
Rotary evaporation concentration	Water bath 40±1℃	Residual liquid volume ≤5ml

Systematic method validation data

Another brand of cigarettes actually tested showed that the NNK detection value was 14.6±0.8ng/stick, and the inter-laboratory comparison RSD was <7%. The four TSNAs were accurately separated by the HP-1MS capillary column gradient program.

Suggestions for implementing differentiated management

Low-tar cigarettes (≤8mg) need to increase the frequency of repeated analysis
The key point of chromatography purification is to use visual pH indication to optimize the column density
