  Trace-level aliphatic amines in pharmaceutical ingredients The determination of aliphatic amines in interfering matrices is a challenging task because protonated amines are often poorly retained on the column. This problem is met by applying ion chromatography using coupled-column matrix elimination.

 

  Economical monitoring of uranium in drinking water Compared to ICP-MS, determining ultra-trace levels of uranium in drinking and mineral water by adsorptive cathodic stripping voltammetry (AdCSV) is a straightforward, much less expensive alternative allowing measurements with superior sensitivity

 

  Ion chromatographic analysis of carbohydrates in essential and non-essential foodstuffs This article describes a straightforward ion chromatographic method that uses 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. While carbohydrate determination of most foodstuffs requires only minimal sample pretreatment such as dilution and filtration, samples with interfering matrices such as protein-containing dairy products have to be dialyzed prior to injection.

 

  Automatic thermal sample preparation for Karl Fischer titration When working with difficult samples, such as plastics, salts or other compounds that release their water slowly or require elevated temperatures to do so, labs turn to the Metrohm 874 USB Oven Sample Processor.
