Product Instruction  

Detection Method	Visible Spectrophotometry
Specification	50T/48S

测定意义：H2S 是一种新型气态信号分子，存在于脑内的神经递质，生理浓度的 H2S 对神经系统海马的长时程增强功能具有重要的调节作用，并对自发性高血压、出血性休克及肝硬化等疾病的过程发挥着重要的病理生理效应。 
测定原理：H2S 与醋酸锌、N, N-二甲基对苯二胺和硫酸铁铵等反应生成亚甲基蓝，亚甲基蓝在 665nm处有最大吸收峰，通过测定其吸光值可计算 H2S 含量。
需自备的仪器和用品：天平、低温离心机、可见分光光度计1ml玻璃比色皿、蒸馏水。
