The method allows determination of organic acids, in soft drinks (juices, fizz drinks) and alcoholic drinks (wines, beer).
The capillary electrophoresis method for evaluation of cations concentration is based on differential migration and separation of cations in electric field due to the difference in their electrophoretic mobility. Identification and quantitative determination of the analyzed cations is performed by indirect detection measuring UV absorption at 254 nm (for “CAPEL® -103RT/104T” systems) or 267 nm (for “CAPEL® -105/105M” systems) wavelength.
The determination is not hindered by the presence of anions of ammonia, lithium, strontuim, barium, manganese, ferrum (II) in the quantities that are typical for the analyzed drinks.

High-sensitivity trace-level measurement of water in organic solvent was performed on-line, continuously in real-time. Parts-per-million sensitivity (10-ppm detection limit) was achieved which previously could only be achieved by the Karl-Fischer titration method.

Total Volatile Organic Compounds (VOCs) is a common measurement required from industrial emissions. Commonly, a single measurement value is obtained through the use of a Flame Ionisation Detection (FID) analyser. The pyrolysis of the gas stream in a FID analyser allows it to make a measurement of the carbon content of the gas stream. FID analyser cannot indicate the relative abundances of different organic species in a gas stream and often have widely different responses for different gases. However, they are taken as the standard reference method for Total VOC emission measurements.

Drinking water supply and distribution systems around the world (a critical and interdependent component of a nation’s infrastructure) are vulnerable to both intentional and accidental contamination. Unusual water quality may serve as a warning of potential contamination. The available physico-chemical sensors utilize general water quality parameters, such as free chlorine, oxidation reduction potential (ORP), total organic carbon (TOC), turbidity, pH, dissolved oxygen, chloride, ammonia, nitrate to detect the contamination. Generally, one or more of these water quality parameters will change due to the injection of a contaminant. However, no single chemical sensor responds to all possible contaminants nor can they give any indication of the potential toxicity of complex mixtures.
