  • What to Expect at Interphex 2007
    particle size analyzers, Raman, fluorescence, pH meters, X-ray fluorescence, ellipsometers, elemental composition and materials characterization analyzers. ( International Portland manufactures 12 different models of class 100 downflow containment booths used for raw material sampling and dispensing
  • Chloride Determination in Copper-Sulfuric Acid Plating Bath
    Equipment: Meter: pH/Millivolt meter. Readability of 1 mV required, 0.1 mV preferred. Specific ion meter will provide direct readout of final answer or concentration factor. Consult manual for millivolt measurement instructions. If the electrode is being used for the first time, please follow
  • Determination of Ionized Calcium in Skim Milk
    Ionized calcium in skim milk can be measured directly in the normal range (1 mM to 4 mM) utilizing the Iotron Calcium Electrode. Potassium Chloride is added to both standard and sample for consistent ionic strength. Equipment: Meter: pH/Millivolt meter. Readability of 1 mV required, 0.1 mV
  • Chloride Analysis in Water
    and swamp waters. Sulfide is easily removed by aeration. Equipment: Meter: pH/Millivolt meter. Readability of 1 mV required, 0.1 mV preferred. Specific ion meter will provide direct readout of final answer or concentration factor. Consult manual for millivolt measurement instructions.
  • Bromide Analysis in Nickel Sulfamate Bath
    may be present in trace amounts. As bromide concentrations may vary widely, use the following method as a general guide line. Equipment: Meter: pH/Millivolt meter. Readability of 1 mV required, 0.1 mV preferred. Specific ion meter will provide direct readout of final answer or concentration factor
  • Bromide Analysis in Water
    The following analysis is valid for bromide levels as low as 0.5 ppm. Check the deionized water used in reagent preparation. The specific conductivity should be no greater than 2.0 uSCM-1 (5 Mohms). Sample solutions should be free of iodide and sulfide ions. Equipment: Meter: pH/Millivolt meter
  • Removal of Chemically Emulsified Oil
    This treatment sequence requires a reaction tank and a pH adjustment tank. The salts and polymers that break the emulsions are added to the tank by means of metering pumps and mixed with mechanical mixers, or injected in line prior to the tank and the pump, using the pump as the mixer. Metals can
  • Improving Energy Efficiency in Pharmaceutical Manufacturing Operations Part I: Motors, Drives and Compressed Air Systems
    (pH and total dissolved solids), flow and temperature. Clean and replace filters and heat exchangers per manufacturer s specifications. (see also the Leak Reduction section below). Specify pressure regulators that close when failing. Check all applications requiring compressed air for excessive
