    Determination of zinc in water by fluorimetric method

    In accordance with WHO’s Guidelines for Drinking Water Quality there is no health-based guideline value of zinc in water concentration. Concentration of zinc in tap water can increase as a result of its dissolution from pipes. Also, elevated levels of zinc may be an indicator of increased concentrations of other toxic metals; thereby zinc in water analysis is an essential analytical task. Lumex Instruments provides sensitive and selective fluorimetric method for the measurement of mass concentration of zinc in water samples using the FLUORAT-02 analyzer.

  • MAXXIFLUX - Lithium fluxes fusion for X Ray Analysis

    The fusion is the dissolution on the sample of flux. The oxides are easily dissolved in Lithium borates. The Lithium Tetraborate (Li₂B₄O₇ -m.p. 920° C ), by having and acid character, react better with basic oxides, as for example the CaO. Therefore, the Lithium Metaborate (LiBO₂ – m.p. 850°C), which has basic character reacts easily with acid oxides, for example:SiO₂. The MAXXIFlux has a high purity level and analytical accuracy, high density, and can be pre-fused or not.
