这些产品基于重量/重量的基本原理进行重量分析制备而成。溶质和溶剂都于Aladdin技术人员利用OIML 可追溯重量进行校准的衡器上进行称重。Aladdin持有校准非自动称量仪器的 ISO17025 认证(INAB 参考:265C)。由此产生的校准重量证书是按照 ISO/IEC 17025 的要求发出的。高性能校准气相色谱仪上通过ISO 17025认证测试方法检验每一种标准品的浓度-质谱联用仪(LC-MS仪器)。利用ISO Guide 34种认证的、与这些苯酚浓度值类似的高纯度二级源苯酚标准液完成GC-MS仪器的校准工作。通过与美国国家标准与技术研究院(NIST)的质谱库进行比较来确定每个分析物的质谱
These products are prepared gravimetrically on a weight/weight basis. Both solute and solvent are weighed on a balance calibrated by Aladdin engineers using OIML traceable weights.Aladdin holds ISO 17025 accreditation for calibration of laboratory balances (INAB ref: 265C). The resulting Balance Certificate of Calibration is issued in accordance with the requirements of ISO/IEC 17025. The concentration of each standard is verified using an ISO 17025 accredited test method on a high performance calibrated Gas Chromatograph - Mass Spectrometer (GC-MS Instrument). The calibration of the GCMS instrument is completed using high purity ISO Guide 34 accredited PAH standards similar in PAH concentration value to these products. The mass spectrum of each of the analytes is confirmed by comparison with the National Institute of Standards and Technology (NIST) mass spectral library
