本标准物质以纯度经准确定值的乙草胺纯品为原料,以HPLC级甲醇为溶剂,采用重量-容量法准确配制而成。
乙草胺,英文名称:Acetochlor,CAS No. :34256-82-1
本标准物质以配制值作为标准值,采⽤⾼效液相⾊谱法-⼆极管阵列检测器(HPLC-DAD)对本批次标准物质和质量控制对照样品进⾏⽐对,核验配制值。通过使⽤满⾜计量学特性要求的制备⽅法,测量⽅法和计量器具,保证标准物质的量值溯源性。
标准值:1000μg/mL,相对扩展不确定度(k=2):2%
标准值的不确定度综合考虑了原料纯度定值结果,制备过程,量值核验以及均匀性,稳定性等引入的不确定度分量。
依据JJF1343-2022《标准物质的定值及均匀性、稳定性评估》,对分装后的样品进行随机抽样,对溶液浓度进行均匀性检验,稳定性考察。结果表明,本标准物质均匀性,稳定性良好。
本标准物质量值自定值日期起,有效期18个月, 研制单位将继续跟踪监测该标准物质的稳定性,有效期内如发现量值变化,将及时通知用户。
1、包装: 本标准物质采用硼硅酸盐玻璃安瓿瓶包装,约1.2mL/支,移取或稀释时请以移液管量取为准。
2、贮存: 运输时应避免挤压,碰撞;冷冻(-18±5)℃,置于阴凉处贮存。
3、使用: 启封前于室温(20±3)℃平衡,并充分摇匀。安瓿瓶一经打开,应立即使用,不可再次熔封后作为标准物质使用。
