    Monitoring of mercury in ambient air

    Mercury, being widespread in environment, has toxic effect on a human organism even at a low concentration. Therefore, quantitativ e determination of mercury in vari ous environments is one of the most important environmental monitoring problems. The use of a mercury analyzer RA-915M/RA-915+/RA- 915Light with Zeeman background correction provides di rect real-time continuous determination of mercury in air from 0.5 ng/m 3 within the overall possible range of me rcury concentration in ambient air.

    Determination of preservatives (benzoic, sorbic acids and their salts) and sweeteners (acesulfame K, saccharine and its salts) in food products and raw materials, and dietary supplements

    Various food additives – preservatives (benzoic acid, sorbic acid, and their salts), sweeteners (Acesulfame K, saccharine and its salts) and others are widely used in food industry for the improvement of food products properties and extension of storage life. The amount of these additives in food products is regulated by technical instructions and other norms.

    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 to European and Russian regulations it is allowed not to indicate on the labels the presence of sulfur dioxide in beverages if its concentration is less than 10 mg/L.

    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.

    Determination of bitter iso- alpha-acids and alpha- and beta-hop acids in beer

    It is important to quantify α- and β-hop acids (humulons and lupulons) as well as bitter iso- α-acids (isohumulons) on the all stages of beer production. Hop acids are the biochemical markers of a certain hop type. Bitter iso- α-acids stabilize the beer foam, suppress the growth of undesirable microorganisms and give the beer its bitter taste.

    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.

    Quality control of oilseeds and pressed oil

    For the manufacturers of edible oils it is very important to control the crushing process at all the stages to achieve the best cost efficiency. In order to provide maximum yield and meet the product specifications it is necessary to monitor process as closely and rapidly as possible. Rapid determination of the key parameters with the use of InfraLUM® NIR analyzers provides the opportunity to control the process at every stage from quality control of oilseeds at intake point to the QC of the final product (liquid or solid).

    Determination of D- and L-isomers of tartaric and malic acids in wines, wine materials, and food additive

    Naturally occurred is predominantly L-form of tartaric acid whereas its D-form and the relevant racemic mixture can be artificially synthesized. Generally, artificial acidification of wine with tartaric acid is allowed by OIV, but only pure L-form must be used for this purpose. Thus the analysis of tartaric acid isomers either in food additives or directly in wine can be an important parameter in clarifying any deviations in wine production. Analysis of isomers of malic acid is also within the necessary oenological procedures stated in OIV recommendations. LUMEX INSTRUMENTS offers the present method which allows determination of L- and D-forms of tartaric and malic acids in wine, wine materials, and special food additives by capillary electrophoresis method.
