Metrohm is pleased to support the food and beverage industry with 4 applications utilizing ion chromatography with pulsed amperometric detection (PAD) for the fully automated determination of multiple GOSs (β-galactooligosaccharides) and carbohydrates in novel foods and instant coffee, respectively, key anions and cations in beer, and organic acids ...
A free Metrohm white paper presents 2 improved methods for simplified sulfite analysis using ion chromatographic separation followed by amperometric (method 1) and conductivity detection (method 2). While method 2 is ideally suited for higher sulfite concentrations in foods with low organic load, method 1 excels due to detection limits as low as ...
Metrohm is pleased to present an application for the straightforward determination of the herbicide glyphosate and its primary metabolite AMPA in drinking water by ion chromatography with pulsed amperometric detection. With a detection limit of approximately 1 µg/L, the method is sensitive enough to comply with limit values in the US, ...

” By their inclusion in the final rule, the following approved methods can be used for determining compliance with National Pollutant Discharge Elimination System permits or other monitoring requirements: D2036-09 (B), Test Methods for Cyanides in Water; D6888-09, Test Method for Available Cyanide with Ligand Displacement and Flow Injection Analysis (FIA) Utilizing Gas Diffusion ...
Cyanide and hydrogen cyanide are highly toxic. Regulations have been established to require the monitoring of cyanide in industrial and domestic wastewaters and surface waters. This test method is applicable for natural water, saline waters, and wastewater effluent. The method may be used for process control in wastewater treatment facilities. The spot test outlined in Test Methods ...
The maintenance-free auxiliary and reference electrodes complement your detection system. This makes amperometric detection more robust and easier to use than ever before. Depending on the application, the direct current mode (DC), the pulsed amperometric detection mode (PAD), the highly flexible ...
Metrohm has developed a straightforward ion chromatographic method using isocratic elution and pulsed amperometric detection (PAD) to sensitively determine water-soluble polyols and sugar alcohols as well as mono-, di- and oligosaccharides in essential and non-essential foodstuffs. ...
