Applications
- AN-PAN-1002Online monitoring of cyanide and gold in gold leaching solution
Gold leaching by cyanidation requires precise monitoring of cyanide and gold. Online process analyzers perform such measurements, improving safety and compliance.
- AN-RS-016Trace Detection of Potassium Ferrocyanide in Table Salt
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.
- AN-SEC-002Gathering information from spectroelectrochemical experiments
In-situ spectroelectrochemistry provides dynamic electrochemical and spectroscopic information concurrently with the redox reaction occurring on the electrode surface. Although different spectroelectrochemical configurations can be used, simple equations explain how to relate electrochemistry and spectroscopy for each experimental setup. This Application Note describes how the quantification of one electrochemical parameter (the diffusion coefficient) is calculated from the spectroscopic data as a proof of this concept.
- TA-023Analyse de l'agent de contraste MRT contenant du gadolinium grâce aux analyses couplées CI-ICP/MS
Cet article décrit l'analyse par chromatographie ionique puis spectrométrie de masse à plasma couplé par induction (ICP/MS), dans quelle mesure la floculation du fer(III) par libération des ions dans le cadre de la préparation d'eaux usées libère des ions gadolinium(III) toxiques.
