    Determination of hesperidin and naringin in juices using CAPEL-105M capillary electrophoresis system

    The method is intended for determination of hesperidin and naringin using capillary electrophoresis technique in order to reveal adulteration of juices. These components are tested in citrus juices, concentrated juices, nectars, juice-containing beverages, and fruit sauces that are produced primarily from oranges, grapefruits, tangerines, lemons, and limes.

  • Empowering Traditional Mass Spectrometry System for Proteomics & Peptide Mapping

    Peptide mapping is an essential step in the structural verification of recombinant proteins and biotherapeutic molecules. In this technique, proteins are digested into peptides, fractionated by traditional liquid chromatography (LC) methods and then analyzed by Mass Spectrometry (MS). Although this approach can be effective for many peptides, it is slow (often 30 minutes or more per sample), requires complex sample preparation and is incompatible with some sample types such as “sticky” peptides....

  • Empowering Traditional Mass Spectrometry System for Biotherapeutics

    Protein-based therapeutics cover a wide range of molecular types, including monoclonal antibodies (mAbs), Fc fusion proteins, and mAbs conjugated with small molecule drugs. The development of protein therapeutics is challenging and requires sensitive analytical techniques. Mass spectrometry (MS) is widely used due to its sensitivity, selectivity, and specificity. MS analysis can now be simplified and automated by integrating this powerful analytical technique with a microfluidic device that incorporates zone...

    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”...

    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®...

    Determination of total sulfur dioxide in wine and beer

    Method allows determination of mass concentration of total sulfur dioxide (sulfurous acid and its salts, food additives E220–E228) in wine, wine materials, beer and beer products by capillary electrophoresis (CE) using capillary electrophoresis system “CAPEL® -105M”. The mass concentration of total sulfur dioxide is regulated by normative documents to be held within 100– 400 mg/L for different types of wine and wine materials and within 20–50 mg/L for beer products. According...
