一般描述

Titrisol®参考缓冲液浓缩液[磷酸盐/氢氧化钠；pH=12.00±0.05 (20 °C)]在经ISO/IEC 17025认可的实验室中采用组合玻璃电极和5点校准法根据DIN 19268的规定对照基于DIN 19266的认证一级标准参考物质进行分析。

Titrisol®浓缩缓冲物质结合易用性和最高精确性，适用于pH仪器的常规校准和监测。要制备现成pH缓冲溶液，只需稀释Titrisol®缓冲液浓缩液即可。

应用


  • Identification of variety-specific metabolites of basil by high performance thin layer chromatography-assisted metabolic profiling techniques: This study identified specific metabolites in different basil varieties using high-performance thin-layer chromatography, employing silica gel 60 H as the stationary phase. The technique allowed detailed metabolic profiling, aiding in the differentiation of basil varieties (Wulandari et al., 2023).


特点和优势

  • 追溯至NIST和PTB的一级标准参考物质
  • 分析标准等级
  • 不确定性数据和可追溯性记录于详尽、针对特定批准的分析证书中。

分析说明

pH值（20 °C）：12.00 +/- 0.05
根据DIN 19266，使用标准缓冲液制备用参比物质进行多点校准（根据DIN 19268）后，用组合玻璃电极稀释至500 ml后测量。
