计算溶液所需的质量、体积或浓度。
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。每一种标志品的密度都是由高性能的经过校准的分光光度计来检测的。而分光光度计的校准是通过经ISO Guide 34认证的分光光度计标准品来完成的。
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 a high performance top
of the range calibrated spectrophotometer. The calibration of the spectrophotometer is controlled
using high purity ISO Guide 34 accredited spectrophotometric standards.
