工作场所有害物质氮氧化物测定的质量保证

Qualtiy Guarantee of Testing Nitric Oxide in Workplace

工作场所空气中产生的有毒物质氮氧化物的测定是用吸收液采集空气样品后送达实验室检测,是采样与显色同时进行,方法的关键是采样前吸收液的配制与采样后样品的运输、保存及其测定,要得到准确、可靠的监测数据,一定要从样品的采集、保存,实验室分析等各个环节加以控制。

The toxic nitric oxide in the air of the workplace is sampled by the adsorption solution and then the laboratory for the test. The sampling and coloration are synchronized. What important is the solution tion, transport, storage and test of the samples, in order to obtain accurate and reliable monitoring data. taken to prepara-
