  • Multi-Parameter Analysis and Enhanced Productivity by the Consolidation of Inorganic Wet Chemistry Methods

    Summary Multi-tasking and time allocations are key components to running an efficient laboratory and decreasing the cost per analysis for pH, conductivity, alkalinity, chloride, fluoride and ammonia.  The cost of analysis has risen over the years while revenue from these parameters has remained the same.  Much of the high cost is due to the use of multiple instruments, multiple ...

  • 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 which makes such solutions conducting. With conductivities of 1,000 µS/ cm or more, an ample supply of mobile ions provides pH electrodes with a ...

  • How should I clean a pH electrode, or revive a damaged electrode?

    Traditional glass pH electrodes are very delicate and need regular care to keep them in good working order. If your electrode has been damaged by exposure to incompatible chemicals such as proteins, heavy metals or sulphides, you may be able to clean and revive it using specialized cleaning solutions… pH electrodes that have a single junction are particularly susceptible to damage, and can ...

  • A polyvinylchloride-based cadmium ion-selective electrode using [Mo2(OAc)2(H2-calix[4]arene)] as an electroactive material

    A highly electroactive material Mo2[(OAc)2(H2-calix[4]arene)] is used as a neutral carrier for Cd2 +  ions in this paper. The membrane is fabricated by using ionophore [Mo2(OAc)2(H2-calix[4]arene)]:poly(vinyl chloride) (PVC): dibutylphthalate(DBP):sodium tetraphenyl borate (NaTPB) in the ratio of 40:300:470:5 respectively and tetrahydrofuran (THF) used as a solvent. The membrane electrode ...

  • pH Electrode Architecture

    A pH Electrode can be compared to a battery in that an electrical voltage is generated between two points that is a function of water chemistry. In the case of a pH electrode the voltage potential is a function of the acidity or alkalinity of the solution in which it is immersed. Note: The terms pH electrodes and pH probes are often used synonymously, despite the fact that there are differences. ...

  • Titrimetric determination of sulfate

    Most methods for the titrimetric determination of sulfate do not work reliably if interfering divalent cations such as calcium and magne¬sium are present in the sample. Using the methods described below calcium and magnesium will not interfere and can even be deter¬mined in the same analysis. IntroductionSeveral different titration methods are used to determine sulfate ...

  • Towards ferroelectric and multiferroic nanostructures and their characterisation

    We summarise here our efforts toward the fabrication and characterisation of ferroelectric and multiferroic films and structures. First, we discuss the challenges related with the fabrication and characterisation of nanostructures of functional complex oxides. In particular, to demonstrate the functionality of our films and especially of our structures, we briefly describe atomic force microscopy ...

  • A voltammetric method for determining free metal activities in aqueous solutions. Part 1: direct current voltammetry of Cd, Cu, and Pb

    A selective and sensitive method for determining free metal activities (M2+) for Cd, Cu and Pb in aqueous solutions is presented based on the Lingane and DeFord and Hume models. Electrochemical and complexation studies were carried out by direct current voltammetry (DCV) and by metal ion selective electrodes (ISE) as a reference method. A voltammetric equation was tested to evaluate ...
