    Determination of protein purity and heterogeneity with capillary gel electrophoresis and capillary isoelectric focusing

    INTRODUCTION

    Antibodies, protein-based therapeutics, and other recombinant proteins are final products in biotechnological and pharmaceutical industry. Determination of their purity, stability, and hetero geneity is of utmost importance since post-translational modifications as well as degradation processes can change drastically the biological activity of these proteins.

    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 water-soluble forms of inorganic cations in soils, clays, peat, wastewater silt, activated sludge, and bottom sediments

    INTRODUCTION

    The content of water-soluble forms of inorganic cations (ammonium, potassium, calcium, sodium, magnesium) is one of the substantial characteristics in agrochemical, land reclamation, and sanitary assessments of soils (arable, hayland, pasturable, forest nursery soils). The cation balance should be controlled during ecological soil monitoring for the human activity impact assessment.

    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.

    Direct AA Mercury determination in cosmetics

    INTRODUCTION

    High mercury concentration can be found in such cosmetic products as skin lightening soaps and creams, makeup cleansing products, and mascara.

    Mercury in cosmetics exists as inorganic and organic compounds. Inorganic mercury (e.g. ammoniated mercury) is used in skin lightening soaps and creams. Organic mercury compounds, such as thiomersal, are used as cosmetic preservatives in makeup cleansing products and mascara.

    Direct atomic absorption mercury determination in tissues and biological samples

    INTRODUCTION

    Mercury and its compounds are highly toxic substances fo r humans. It occurs naturally and exists in various forms: elemental (or metallic); inorganic (e.g. mercuric chloride); and organic (e.g., methyl- and ethylmercury). These forms all have different toxicities and implications for health. Among naturally occurring mercury compounds, methylme rcury exerts a significant influence (neurotoxic action) on human health.

    Chemiluminescense based analyzer for semiconductor applications

    NOx detection is an innovative approach in CMP (Chemical Mechanical Polishing) process control. CMP smoothens the wafer surface with a combined chemical and mechanical polishing procedure. During production, wafers are coated by a thin layer. To avoid damage to the wafer surface, for instance by stress cracks, the NOx emitted as soon as the wafer is plane and blank must be measured. Therefore, a high-resolution NOx-detector, capable of determining exactly when the polishing process must be stopped, is essential. This approach is used successfully in manufacturing and development lines worldwide, since 1996.

  • Early warning systems for drinking water

    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.

  • Early Warning systems for surface water industry

    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.
