  • 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.

  • Surface Science

    SIMS - for depth profiling, surface composition measurement, and elemental imaging, Hiden's SIMS Workstation provides a complete analytical facility. RGA - The Hiden quadrupole mass spectrometers provide high sensitivity detection capability for the most demanding XHV/UHV vacuum environments. The pulse ion counting detector enables measurement of both positive and negative ions through 7 continuous decades, the integral accumulation mode being used for the capture of discreet particle events. UHV Temperature Programmed desorption studies (TPD) - Hiden Analytical’s 3F/PIC mass spectrometers with pulse ion counting detection are available configured specifically for UHVTPD providing fast, wide dynamic range detection of multiple species, capturing the entire desorption event. The Hiden IDP ion desorption probe is a quadrupole mass spectrometer configured for analysis of low energy ions in electron and photon stimulated desorption studies.

  • Water quality monitoring systems for high water purifier industry

    The monitoring of “Ultra Pure Water” or “High Purity Water” requires the lowest possible detection limits for process analyzers. Resistivity is often around 18 MΩ. Dedicated instruments can detect infinitely small amounts (ppt e.g. parts per trillion) of ions.

  • Laboratory Ion Analyses

    Our single ion and multi ion kits allow for real-time laboratory analysis of one to six ions simultaneously with one probe. These ion sensors along with the reference electrode are solid state which allows for easy handling, storage and maintenance. No filling solutions nor buffers are required. The sensors are based on carbon nanotube technology allowing for reliable and reproducible measurement of ions in liquids.

  • Process Belt Meshes For Forming and Laying Down

    CONDUCTO process belts are antistatic process belt solutions for the nonwovens industry individually geared to the particular nonwoven laydown process. Due to their steady and consistently high electrostatic discharge, they are ideal for the manufacture of nonwoven materials that are produced in airlaid processes, carding processes and in spunbond/meltblown processes. Typical of the CONDUCTO process belt family are the woven-in bronze wires that guarantee the reliable discharge of nascent electrostatics.
