  • Liquid Analysis in Mineral Processing
    This paper describes the process applications that take place after mining and prior to refining as they relate to pH / ORP, dissolved oxygen and conductivity.The implementation of the proper analytical sensors in the common metal extraction processes used today in the minerals industry go far
  • MICRO: Testing liquid-handling system components to ensure purity and reliability
    released specifications for particulate and metallic contamination in components. Not included, however, are specifications for particle release, while requirements for metallic extractables are based on extraction into water. Section 3.7 states that the relative leach-out performance of polymer
  • Moving Beyond the Batch
    By Bill Swichtenberg, Senior Editor Phoenix Chemicals Proctor thinks it is important to consider the entire process as a candidate for continuous processing (much as Novartis-MIT is doing) and not just the reaction stage. For example, many chemical processes rely on a liquid-liquid extraction
  • When Less is Much, Much More
    , four-channel, and HPLC-integratable analysis configurations. These microreactors can interface with a liquid-liquid extraction module for rapid purification. Syrris focuses on development-worthy microreactors, preferring to leave systems for large-scale manufacturing to other companies. Nevertheless
  • Polymer Solvent Drying
    Problem: The production of many petroleum and biomass based polymers involves contact with chemical solvents. This contact may occur during the polymerization/reaction step, or to extract impurities from the final product. Typically, the liquid solvent is first removed mechanically by centrifuge
  • Medical Device Link .
    testing the cleanliness of an irregularly shaped part (and therefore testing the effectiveness of the cleaning method), all methods follow two steps. The first is to extract the particles from the device into a liquid; the second is to test how many particles the liquid now contains. This article
  • MICRO: Ultrapure Fluids by Anurag Kumar (Jan 2000)
    for determining a variety of organic compounds using liquid-solid extraction and elution with organic solvents. However, none of those methods can identify and quantitate <1-ppbw levels of some semivolatile organic compounds, such as siloxanes, and plasticizers, such as dioctyl phthalate (DOP) and TXIB
  • Tuning in to New Solvents
