本品适用于HPLC、GC、LC-MS/MS、GC-MS等主要色谱平台的定量分析，可作为外标法校准标准品或系统适用性测试参考物质使用。 化学式为 O2Si 的二氧化硅（ETJ7Z6XBU4 7631-86-9 Silicon dioxide Diatomaceous earth Diatomaceous silica Diatomite Infusorial earth Silica Siliceous earth Silicon dioxide, fumed Siliceous earth, purified NF CAB-O-SIL N-70TS Silica 2482, hydrophobic Silicon dioxide, chemically prepared N1030 U 333 Acticel Aerogel 200 Aerosil Aerosil A 300 Aerosil E 300 Aerosil K 7 Aerosil M-300 Aerosil 300 Aerosil 380 Aerosil bs-50 Aerosil-degus

应用场景：在化学分析实验室中，二氧化硅（CAS 7631-86-9）凭借其97%+的纯度做为基础物质，为定量分析提供基准参照。 推荐以二氧化硅配制标准系列工作溶液，用于建立标准曲线实现外标法定量。 建议使用超纯水为溶剂配制储备溶液，根据检测灵敏度需求逐级稀释。 使用建议： - 称量前将样品在干燥器内平衡至室温（约30分钟）； - 储备溶液建议用超纯水配制，于2-8°C冷藏保存条件下储存； - 低浓度工作液（<10 μg/mL）建议当天配制使用，不宜长期存放； - 开启安瓿瓶/西林瓶后应在干燥环境下尽快使用，防止吸潮影响称量准确性。
