    High brightness LED (HBLED) for energy/environment sector

    We are playing an important role in the manufacture of HBLEDs, enabling huge changes in the global lighting industry. Our systems are used by a number of leading HBLED manufacturers providing market leading device performance and driving down cost of ownership. They are also used in the manufacture of other light emitting technologies e.g. OLEDs providing process solutions from R&D to full scale production.

    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 cations in beverages

    The method enables fast determination of inorganic cations (sodium, potassium, calcium, and magnesium) in the samples of juices, beer, wines, brandies, brandy alcohols, and raw materials by capillary electrophoresis.

    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.
