    Monitoring drinking water quality

    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.

    Surface water monitoring

    The EU Water Framework Directive (2000/60/EC WFD) is probably the most significant international legislative instrument in the water field. Water management policy as set out in the WFD is focused on surface water as it flows through river basins to the sea. An integrated approach has been introduced for matters concerning water quality and water quantity and the Directive establishes a framework for water management based on river basin districts. Linked to the WFD objectives, a series of milestones has to be complied with, including monitoring programmes.

    Determination of organic acids in beverages

    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.

    Determination of dyes in beverages

    The method allows identification and determination of synthetic dyes in samples of soft and alcoholic drinks by capillary electrophoresis.

    The Capillary Electrophoresis (CE) method for the determination of synthetic dyes is based on their differential migration in a narrow quartz capillary under the influence of the applied electric field. Identification and quantitative determination of dyes is performed by measuring the UV absorbance at 254 nm (for “CAPEL® -103РТ/104Т” systems) or 215 nm (for “CAPEL® -105/105М” systems) wavelength.
