目的对串联法与《GBZ/T16029-2004》中一氧化氮和二氧化氮的采样方法进行比较。方法分析GBZ/T16029-2004法与串联法测定结果。结果 GBZ/T16029-2004法发生二氧化氮与总氮的量倒置。结论利用串联法采集一氧化氮和二氧化氮更方便,数据更精确。
Objective To compare the sampling method of tandem method and nitrogen monoxide and nitrogen dioxide in “GBZ / T16029-2004”. Methods The results of GBZ / T16029-2004 method and tandem method were analyzed. Results The amount of nitrogen dioxide and total nitrogen in GBZ / T16029-2004 method was inverted. Conclusions It is more convenient and more accurate to collect nitric oxide and nitrogen dioxide using the tandem method.
