通过氰化法浸金需要对氰化物和金进行精确监测。在线过程分析仪可进行此类测量，从而提高安全性和合规性。

Potassium ferrocyanide (KFC) is an anti-caking compound added to table salt. Although this is a common non-toxic food additive, its spectroscopic response is representative of analogous cyanide compounds. Trace detection of other cyanides in food products is essential to the safety of consumers, as they can be toxic at oral consumption levels as low as 20 μg/g.This application demonstrates rapid trace analysis of potassium ferrocyanide in table salt with Misa (Metrohm Instant SERS Analyzer), in a simple assay format with minimal use of laboratory reagents.

原位光谱电化学可在电极表面发生氧化还原反应的同时提供动态电化学和光谱信息。尽管可以使用不同的光谱电化学配置，但每个实验装置的电化学和光谱学之间的关系都可以用简单的方程式来解释。 本应用简报介绍了如何通过光谱数据计算出一个电化学参数（扩散系数）的量化值，以此证明这一概念。

本文描述使用离子色谱法然后借助电感耦合等离子体质谱法（ICP/MS）检测在废水处理过程中，铁（III）絮凝操作经聚合释放有毒钆（III）离子到何种程度。
