描述

應用

• Development of Cyanide Detection Methods: Utilizing high-performance liquid chromatography-tandem mass spectrometry, researchers have developed concurrent determination methods for cyanide and thiocyanate in human and swine blood. This technique ensures high accuracy and sensitivity, crucial for toxicological analysis and forensic investigations (Alluhayb et al., 2023).
• Fluorometric Cyanide Sensing: A novel fluorometric probe offers high selectivity for sensing cyanide in aqueous solutions, which can be applied to quantitative determinations and living cell imaging. This advancement supports biochemical assays requiring precise cyanide measurements, enhancing safety and detection capabilities in both environmental and clinical settings (Satheeshkumar et al., 2023).

分析報告

浓度     β (CN⁻)：990 - 1010 mg/l
测定方法：银量滴定法。
该溶液的含量是用硝酸银标准溶液（货号1.09081）测定的，该标准溶液是用容量标准氯化钠（货号1.02406）标定的。扩展测量不确定度为± 0.7 %（k=2，覆盖因子为95%覆盖率）。认证值可通过体积标准氯化钠追溯至一级标准品NIST SRM 999b（NIST：美国国家标准技术研究院）。该过程由德国Darmstadt Merck KGaA公司认可的校准实验室根据DINDIN EN/ISO 17025进行测定。
