  • Instrumentation and Operational Considerations for On-Line pH Measurement in Samples Below 10µS/cm Conductivity

    Instrumentation and Operational Considerations for On-Line pH Measurement in Samples Below 10µS/cm Conductivity

    Ordinarily pH measurements are made in water with 1,000 to 10,000 µS/cm conductivity. The conductivity comes from dissolved solids which are typically salts but also acid or base. These dissolved substances are in the solution in ion form ...

  • pH/ORP Sensors for Metallurgical Applications

    pH/ORP Sensors for Metallurgical Applications

    Importance of pH Measurement Hydrometallurgical concentrating and refining applications require pH/ORP sensors to withstand aggressive environments while maintaining accurate measurement. Processes such as cyanide leaching (e.g gold) and ...

  • Boiler Dissolved Oxygen Control

    Boiler Dissolved Oxygen Control

    DISSOLVED OXYGEN CHEMISTRY Dissolved Oxygen (DO) is a measure of the amount of oxygen, usually thought of as a gas, that is dissolved in a liquid such as water. Oxygen is essential to life and is also the most common element found taking part in ...

  • Stop metal losses in processes with Sulphide, Cyanide, Ammonia and Pressure Fluctuations

    Stop metal losses in processes with Sulphide, Cyanide, Ammonia and Pressure Fluctuations

    Abstract Losses of metal are often traced to incorrect pH/ORP signals in floatation, leaching, extraction, electrolysis, and precipitation processes, aggravated by pressure changes. IC Controls a Canadian mining sensor manufacturer developed a new ...

  • Total Dissolved Solids (TDS) Measurement

    Total Dissolved Solids (TDS) Measurement

    Definition Total Dissolved Solids (TDS) is a measure of the sum of all inorganic and organic substances in a liquid in molecular, ionized or micro-granular colloidal suspended form. The solids must be small enough to survive filtration through a ...

  • Conductivity Measurement in high purity water samples below 10 microsiems/cm

    Conductivity Measurement in high purity water samples below 10 microsiems/cm

    High Purity Water Resistivity/ Conductivity Measurement Ultra-Pure Water without any chemical impurities will still have a conductivity because of the presence of H* and OH" ions due to the self-ionization of water. Ultra-pure water has a ...

  • Reliable pH measurement in Oily applications

    Reliable pH measurement in Oily applications

    pH measurement in the petrochemical industry is frequently extremely difficult. Operating in high temperatures with highly reactive contaminants traditional pH reference electrodes can, in some applications, last only days. IC Controls 613 sensors ...

  • Modem sustainable cyanide destruction control

    Modem sustainable cyanide destruction control

    Industrial Process Description Cyanide-containing waste is produced in various industries such as mining and electroplating. Processes such as stripping, cleaning, and plating generate wastes that can include metal cyanide complexes with alkaline ...

  • Pure water pH measurement in low conductivity samples

    Pure water pH measurement in low conductivity samples

    Normally, pH measurements are made in water with 1,000 to 10,000 uS/cm conductivity. The conductivity conies from dissolved solids, typically, salts plus net acid or base which explains the exhibited pH. These dissolved substances are in the ...

  • Chlorine Theory & Measurement

    Chlorine Theory & Measurement

    Chlorine, dissolved in liquid is one of the most effective and economical semi-killers for the treatment of water to make it potable or safe to drink. Chlorine`s powerful disinfectant qualities come from its ability to bond with and destroy the ...

  • Conductivity Theory and Measurement

    Conductivity Theory and Measurement

    Electrical conductivity is a measure of the ability of a solution to cany* a current. Current flow in liquids differs from mat in metal conductors in that electrons cannot flow freely, but must be carried by ions. Ions are formed when a solid such ...

  • pH Theory & Measurement

    pH Theory & Measurement

    WHAT IS pH? pH is a short form for the Power (p) of Hydrogen (H). pH is defined as the negative log of the hydrogen ion activity, aH~ or the effective hydrogen ion concentration. Descriptive Definition pH is a unit of measure which describes the ...

  • ppb Dissolved oxygen measurement

    ppb Dissolved oxygen measurement

    Dissolved oxygen (D.O.) measurement is one indicator of water quality because oxygen is a common element contributing to corrosion reactions. This corrosion reaction provides the need for low level D.O. control since dissolved oxygen is responsible ...

  • ppm Dissolved oxygen measurement

    ppm Dissolved oxygen measurement

    Dissolved oxygen (D.O.) levels are used as a general indicator of water quality. Oxygen is essential to life and vital for countless aquatic forms. D.O. level control is critical in numerous applications ranging from the monitoring of industrial ...
