环境标准样品主要用于环境监测及分析测试中的质量保证和质量控制,亦可用于分析仪器校正、分析方法比对和分析技术仲裁。
本标准样品采用高纯试剂在超净间中准确配制,分装于20毫升安瓿内,经均匀性检验合格。其标准值和不确定度是由多家实验室用
原子吸收法进行分析测定,并经数理统计处理后确定的。
本标准样品应在阴凉处保存。
临用时割开安瓿,用10毫升干燥洁净移液管从安瓿中准确移取浓样10 毫升于250 毫升容量瓶中,用1%硝酸定容。稀释后标准样品溶液浓度见下表:
The Environmental Reference Materials (ERMs) are primarily used in quality assurance and quality control in the process of environmental monitoring and analysis, and it can also be used in analytical instrument correction, analytical method contrast and analytical technology arbitration.
This ERM was prepared in super-clean lab with high pure reagents and sub-packed in 20ml ampoules. No significant differences in concentration among sub-samples were found. The certified value and uncertainty were based on the analytical results of eight labs by
AAS method.
This ERM should be stored at a dark and cool place.
When you use this ERM, please carefully break open the ampoule at the neck and pipette 10 ml from the ampoule into 250 ml volumetric flask and bring to volume by 1% HNO3 solution.
The concentration of the diluted solution is as following:
铅 Pb 0270109
