一般描述

UV/VIS 和红外光谱中分析结果的准确性取决于是否使用非常纯的溶剂进行样品制备。Uvasol<TMSYMBOL></TMSYMBOL> 系列是特别被计为用于光谱学和其它需要最高光学纯度化学物质的应用领域。精制过程使得应用更加安全并避免由痕量 UV(紫外线)、IR(红外线)和荧光污染引起对分析结果的错误判断。Uvasol<TMSYMBOL></TMSYMBOL> 溶剂可提供最佳的紫外线透射率。在所有质量标准中,均确定了5种典型波长的最小透射率。

应用


  • Quantitative determination of nitrous oxide in human blood by HS-GC-MS: forensic application of two fatal poisoning cases.: This study leverages n-Pentane in headspace gas chromatography-mass spectrometry (HS-GC-MS) for the forensic analysis of nitrous oxide in human blood. Highlighting its importance in forensic science, the research demonstrates n-Pentane′s utility in providing accurate and reliable measurements essential for legal and medical evaluations (Li Z et al., 2024).
