对一种新开发的高流速可吸入尺寸选择性旋风采样器(GK 4.162-也称为可吸入空气采样旋风铝大型(RASCAL))进行了校准,以确定其最佳操作流速。联合王国的健康与安全实验室和美国国家职业安全与健康研究所的两个实验室使用两种不同的方法进行了实验:(1)多分散气溶胶和飞行时间直接阅读仪器(空气动力学粒度仪);(2)单分散气溶胶和空气动力学粒度仪。旋风的测量性能数据进行了评估,对国际可吸入公约使用的偏差地图的方法。虽然使用不同的气溶胶和检测方法对GK4.162旋风分离器进行了测试,但三个实验室的结果基本相似。基于实验室结果的一致性,推荐流速为9.0 L/min。
A newly developed high flow rate respirable size-selective cyclone sampler (GK4.162—also known as the Respirable Air Sampling Cyclone Aluminum Large (RASCAL)) was calibrated to determine its optimum operating flow rate. The Health and Safety Laboratory in the United Kingdom and two laboratories from the National Institute for Occupational Safety and Health in the United States conducted experiments using two different methods: (1) polydisperse aerosol and time-of-flight direct reading instrument (Aerodynamic Particle Sizer (APS)) and (2) monodisperse aerosol and APS. The measured performance data for the cyclone was assessed against the international respirable convention using the bias map approach. Although the GK4.162 cyclone was tested using different aerosols and detection methods, the results from the three laboratories were generally similar. The recommended flow rate based on the agreement of results from the laboratories was 9.0 L/min.
