    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.

    DETERMINATION OF TOTAL PETROLEUM HYDROCARBONS (TPH) IN WATER BY FLUORIMETRIC METHOD

    Total petroleum hydrocarbons (TPH) is a term used to describe a large family of several hundred chemical compounds that originally come from crude oil; the main and most specific part of these compounds are non-polar and slightly polar hydrocarbons of the aliphatic, aromatic and alicyclic structure. These compounds are harmful to humans and animals if absorbed through the skin, ingested, and inhaled thus claiming the analytical control of THP content in water as a global issue. Quantification of TPH in water is typically done using rather expensive chromatography techniques. Lumex Instruments developed fluorimetric method for cost-effective petroleum hydrocarbons in water determination using FLUORAT-02 analyzer. The method is based on measuring the fluorescence intensity of oil products after their extraction from water phase by hexane.

    Analysis of Methylimidazoles in Caramel Colored Carbonated Beverages

    Caramel colorings are used as additives in a broad range of food and beverage products to impart a desired color, but have no nutritional or preservative function. Recently, the potential hazard to humans of ammonia- and ammonia-sulfite-process caramel colorings was raised, because they contain the by-product 4-methylimidazole, which is a potential carcinogen.1 The methylimidazole compounds are difficult to analyze due to their polar nature and low molecular weight. Traditional reversed phase techniques are unsuccessful in retaining these small polar compounds. Therefore, most HPLC methods utilize ion-exchange resins for analysis. Another common method involves GC analysis after the analytes first undergo a derivatization step. The purpose of the work shown in this article was to develop a simple and fast analytical method to determine the levels of 2-methylimidazole and 4-methylimidazole in caramel colored carbonated beverages.

    Analysis of Isocyanates Using the ASSET™ EZ4-NCO Dry Sampler

    Isocyanates are used as a raw material to produce a number of products . Personal exposure can occur while the products made with isocyanates are being applied, or when the materials are removed by grinding or thermal degradation. Workers who are exposed to these compounds are at risk for respiratory disorders and asthma. The highly reactive nature of the isocyanate compounds and the low occupational exposure limits put high demands on both sampling and analytical techniques for monitoring of isocyanates in air. We investigated the performance of the LC-MS and LC-MS-MS methods in the analysis of isocyanates using the new ASSET™ EZ4-NCO Dry Sampler. We found that the analytical method can successfully reach the quantitation limit for most isocyanates of 5 ng/mL in the final sample when LC-MS-MS analysis was used and the quantitation limit of 10 ng/mL when LC-MS analysis was used. All 11 compounds were well-resolved chromatographically using a 15 cm Ascentis Express C18 column.

    Determination of heavy metals in food

    This analytical procedure is intended for measuring the content of the elements (cadmium, lead, arsenic, tin, chromium and mercury) in the samples of food products by atomic absorption spectrometry with electrothermal atomization using an “MGA-915M” Graphite Furnace AA Spectrometer.

    The method is based on measuring resonance radiation absorption that occurs when the radiation passes through a layer of atomic vapor in the electrically heated graphite furnace of the “MGA-915M” AA spectrometer. The concentration of the elements is determined from the integrated analytical signal and is calculated using a preset calibration graph. The samples of food products are digested prior to analysis in accordance with standard methods.

    DETERMINATION OF FATTY ACID METHYL ESTER (FAME) CONTENT IN DIESEL FUEL OR DOMESTIC HEATING FUEL BY MID-IR SPECTROSCOPY

    Presence of fatty acid methyl esters (FAME) in diesel fuel or domestic heating fuel (both hereinafter referred to as diesel fuel) is a signal of blending with biodiesel. The control of FAME content in diesel fuel is an essential and actual task because of the need of the right fuel identification and registration of possible FAME impact on engines and fuel systems. To control the compliance one of the most accurate, rapid and simple methods is EN 14078:2014. Lumex Instruments provides user-friendly analytical solution for EN 14078:2014 implementation using FTIR spectrometer InfraLUM FT-08 and powerful SpectraLUM software package. The method is based on measuring the transmission spectra of a sample of diesel fuel in the mid-IR spectral range. Consequent calculation of the FAME concentration is performed by InfraLUM software automatically by comparison of peak height against a calibration curve.
