为支撑环境空气臭气监测方法标准的有效实施,采用称量法制备浓度水平为60 μmol/mol的氮气中正丁醇标准气体。开展了高纯原料纯度分析,建立了正丁醇标准气体的气相色谱分析方法,评价了分析方法的精密度、检出限及线性,建立了正丁醇标准气体制备技术,考察了正丁醇标准气体制备一致性和涂层气瓶适用性,通过放压试验及稳定性研究确定了样品最低使用压力和样品有效期,并开展了量值不确定度评价。结果表明,所建方法具有良好的精密度及线性,氮气中正丁醇标准气体具有良好的制备一致性,涂层气瓶可满足氮气中正丁醇标准气体的制备需求。在10~2 MPa压力范围内,压力变化对正丁醇量值的影响不显著,样品在16个月的时间稳定性研究中组分量值稳定。采用称量法研制的氮气中正丁醇标准气体的相对扩展不确定度(
k
=2)为2%,量值可有效溯源至SI基本单位,可有效支撑我国环境空气和废气中臭气监测及质量管理工作。
To support the effective implementation of environmental odor monitoring method standards,the 1-butanol certified reference material with a concentration of 60 μmol/mol in nitrogen was prepared using the weighing method. The purity analysis of high-purity raw materials was conducted. An analytical method based on gas chromatography was developed for sample anal
ysis,and its precision,detection limit,and linearity were systematically evaluated. Furthermore,the preparation technology for the 1-butanol certified reference material was established,the preparation repeatability and coated cylinder suitability were also investigated. The minimum operating pressure and validity period of the sample were determined through pressure release experiments and stability studies. Afterwards,the uncertainty of the 1-butanol certified reference material was evaluated. Results showed that the analytical method exhibited excellent precision and linearity. The 1-butanol certified reference material in nitrogen displayed high preparation repeatability. The coated cylinders were confirmed to be suitable for preparing 1-butanol certified reference material in nitrogen. Pressure variations within the range of 10 MPa to 2 MPa had no statistically significant effect on the characteristic values of 1-butanol. The characteristic values can remain stable throughout the 16-month validation period,confirming long-term stability. Overall,the relative expanded uncertainty(
k
=2) of 1-butanol certified reference material in nitrogen developed by weighing method was 2%. The certified values are fully traceable to SI units through rigorous calibration protocols. The 1-butanol certified reference material provides a reliable reference for enhancing the accuracy and comparability of odour monitoring and quality management in China’s ambient air and industrial exhaust systems.
