    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.

    Monitoring Raw Water Intake

    The Situation: Hydrocarbons in water intake used for municipal drinking water and desalination systems are commonly limited to 1 part per million. Problem: Naturally occurring organics in raw water are typically treated with chemicals. Total Organic Carbon (TOC) analyzers in the water treatment system can alert technicians when some type of organic material is present but cannot differentiate between natural organics, such as algae or leaves and hydrocarbons. Solution: A fluorescence monitor can be configured for sensitivity to hydrocarbons, with no significant response to other organics. The TD-4100XDC has the highest sensitivity to hydrocarbons in raw water, has a low cost of ownership, and can be modified with Teflon, Monel, and other corrosion resistant materials for sea water environments.

  • Liquid Rock - Prevening Scale Formation from Ground Water Hardness

    Groundwater is in contact with soil and rock minerals. Significant amounts of the minerals are dissolved in the groundwater. Elevated water hardness is the result of the water interaction and partial dissolution of carbonate minerals. Scale formation is a crystallisation process. Crystals are a highly organised arrangement of molecules. The determining circumstances for a successful crystallisation event include concentration, temperature, pressure and chemical environment. Suitable conditions for the formation of a crystal require numerous factors to coincide. CALSTAT RO-30 provides crystallisation interference at a molecular level :  Excellent results are achieved at low trace quantities of product. Calstat RO-30 dosed at trace levels of 4-10 kg per million litres  Corrosion on steel surfaces is reduced or eliminated  For drinking water production with RO (reverse osmosis) systems, membrane fouling is reduced.
