油基液体颗粒计数器校准用标准物质的研制及应用
|
摘要
针对油基液体颗粒计数器(APC)的准确校准需求,采用重力沉降、超声筛分和扫描电子显微镜等制备及测量技术,开展准单分散中级试验粉尘颗粒标准物质(AM-MTD-CRM)的研制。标准物质粒径涵盖了APC的常用测量范围,定值不确定度小于2.5%(k=2),远低于现有多分散中级试验粉尘标准物质(P-MTD-CRM)的定值不确定度。所研制AM-MTD-CRM的定值不确定度小、粒径分布窄,解决了P-MTD-CRM中粒径测量准确性差、大粒径范围统计颗粒数量少等问题,使得APC校准结果不确定度得到很大改善。
For the purpose of accurate calibration for the oil-based liquid automatic particle counter(APC), the preparation and measurement techniques such as gravity sedimentation,ultrasonic sieving and scanning electron microscope(SEM), were used to develop the approximately-monodispersed MTD certified reference materials(AM-MTD-CRM). The series particle size CRM cover the routine measurement range of APC, and the uncertainty of the certified value was less than 2.5%(k=2), which was far below the uncertainty of polydisperse MTD CRM(P-MTD-CRM). Because of the low uncertainty and the narrow particle size distribution of the AM-MTD-CRM, which overcome the difficulties of poor accuracy of particle sizing and less particle statistics for P-MTD-CRM, it makes the APC calibration uncertainty is greatly improved.
