  • Real Time TOC Analysis in Steam and Condensate

    Executive Summary Steam in petro/chemical plants could be contaminated with hydrocarbons (TOC = Total Organic Carbons) from various sources. In any case this is a sign for defects in the process, whether it they occur in the heat exchanger, the blow down vessel, the condensate recovery or other parts of the system. Conventional solutions to monitor such contaminations use TOC- ...

  • A real-time operation of the Three Gorges Reservoir with flood risk analysis

    Risk analysis is essential to reservoir operation. In this study, a new analysis for reservoir operation is proposed to enhance the utilization rate of the flood water from the Three Gorges Reservoir (TGR) during the flood season. Based on five scenarios of hydrology forecasting with the adaptive neuro-fuzzy inference system (ANFIS), a multi-objective optimum operation was implemented ...

  • Real-time Total Microbial Measurement For Water Distribution Systems

    A well-managed water distribution system is essential for maintaining a healthy water supply. The World Health Organization, the directing and coordinating authority on health (World Health Organization, 2008), has compiled the Water Safety Plan which reflects this. With over 2.3 million deaths per year caused by water born diseases (Davidson, et al., 2005), safeguarding water systems is of ...

  • Rapid and specific detection of Salmonella in water samples using real-time PCR and High Resolution Melt (HRM) curve analysis

    A real-time PCR assay combined with a pre-enrichment step for the specific and rapid detection of Salmonella in water samples is described. Following amplification of the invA gene target, High Resolution Melt (HRM) curve analysis was used to discriminate between products formed and to positively identify invA amplification. The real-time PCR assay was evaluated ...

  • AquaLab Analyzer provides real-time phosphorus measurement in Everglades

    When it comes to ecosystem sustainability, Florida is no backwater. The South Florida Water Management District, which includes the unique Everglades habitat, had a major challenge. The EPA and various governmental authorities have defined limits for many water quality parameters to support a water body’s designated use. Any physical, chemical or biological condition that threatens the designated ...

  • Webinar Highlights: Microfluidics for macromolecules

    Hi, I’m Jim Murphy, Principal Consulting Chemist at Waters, and I recently collaborated with Lucinda (Cohen) Hittle to present an exciting webinar on the use of microflow chromatography for macromolecules.  Lucinda, a Director of Discovery Bioanalytics at Merck, presented an overview of the use of LC-MS for peptide analysis along with various case studies for in vitro and in vivo ...

  • Caltech working to solve the world`s energy problems with the help of inVia

    Fossil fuels are the world's main fuel source for transportation, heating and generating electricity. As a by-product, high levels of CO2 are released into the atmosphere. With the drive for sustainable energy production, a method that generates easily-stored fuel from sunlight—and absorbs CO2—is a very attractive proposition. The California Institute of Technology ...

  • Water analysis

    A complete tap water analysis includes the determination of the pH value, the alkalinity and the total water hardness. Both the pH measurement and the pH titration by means of a standard pH electrode suffer from several drawbacks. First, the response time of several minutes is too long and, above all, the stirring rate significantly influences the measured pH value. Unlike these standard pH ...
