  • I66 the CADMIUM STANDARD CELL. a STANDARD Cell with A
    i66 G. A. HULETT. [VOL. XXIII. THE CADMIUM STANDARD CELL. BY GEORGE A. HULETT. A STANDARD cell with a low temperature coefficient was de- ^~*- vised by Mr. Edward Weston in 1891.1 By substituting cad­ mium sulphate and cadmium amalgam for the zinc sulphate and zinc of the Clark cell, it was found that the temperature coefficient of the cell was reduced 95 per cent., and when the solid cadmium sulphate was dispensed with and only a solution of cadmium sul­ phate used in the cell, the temperature coefficient was still less. With a solution saturated at o° C, Barnes and Lucas found2 that the E.M.F. of the cell was constant for all ordinary temperature changes. This latter combination is a valuable laboratory instru­ ment, but is not sufficiently reproducible or constant to serve as a standard of E.M.F. The Clark cell has a variation of E.M.F. of over a millivolt per degree, and for accurate work requires a very exact control of the temperature for a considerable time. The saturated cadmium cell has only one twentieth of the temperature coefficient of the Clark cell and many other desirable features, so that considerable work has been done in testing its reproducibility and constancy. A. Dearlove3 found that attention must be given to the cadmium amalgam and concluded that it was best to use a 12.5 per cent. amalgam, made by melting together one part of cadmium and seven parts of mercury. Since then considerable work has been done on cadmium amalgams. Kerp and Boettger4 concluded that the solid which separates from cadmium amalgams of over 5 per cent, was a compound represented by the formula Cd2Hgr However, from the work of Bijl5 and Puschin 6 it appears that between about 5 and 15 LU.

An alternative model of the Nernst equation is derived to more appropriately represent the PEMFC system where reactant concentration is instead considered as the activity. Ex situ gas diffusion electrode (GDE) measurements are used to examine the dependency of temperature, electrolyte concentration, catalyst surface area and composition on the measured OCP in the absence of H2 crossover. This is supported by single-cell OCP measurements, wherein RH was also investigated. This contribution provides clarity on the parameters that affect the practically measured OCP as well Citation: Mardle, P.; Cerri, I.; Suzuki, as highlighting further studies into the effects of catalyst particle surrounding environment on OCP T.; El-kharouf, A.

It also removes metal quality indicating free oxygen dissolved in water.

  • Water Quality Procedures
    WAB Field SOP 2018 Revision Date: 8/22/2018 CHAPTER 3. WATER COLLECTION PROTOCOLS Overview A sonde is a collection of multiple sensors and probes housed into one casing and designed to give readings on multiple parameters simultaneously (often referred to as a Multi-Parameter Sonde). Sondes can vary in length, diameter, and housing construction. The most common four sensors on sondes are Temperature, pH, Dissolved Oxygen, and Specific Conductance (typically housed in a 2-inch diameter casing). Larger sondes (e.g., 3.5 – 4-inch diameter casing) can be equipped with additional, larger sensors and probes (e.g., Depth, Chlorophyll-a, and Turbidity). On some sondes (e.g., YSI models) the sensors and probes can easily be changed or replaced by the user. On other sondes (e.g., Hydrolab models), the sensors and probes cannot be easily changed without opening the sonde housing and electronics (either by a very experienced user or by sending the instrument back to the manufacturer’s service department). Figure 3-1. Example of a YSI 660 XL Sonde (right) and a 650 MDS Display Unit (left). Sensors and probes may utilize drastically contrasting technologies to measure a parameter. For example, one sonde may have a Dissolved Oxygen sensor that utilizes Water Collection-Overview Page | 3-1 WAB Field SOP 2018 Revision Date: 8/22/2018 the smaller Clark-cell technology (it has a membrane) with a stirrer; another sonde may use a similar Clark-cell technology and not have a stirrer; yet another sonde may use the larger Luminescence (LDO) technology (no membrane). In this case, the different sensor/probe technologies respectively offer pros and cons based on size the accuracy of the reading and size of the sonde casing required to house the sensor.

    CLARK AND WESTON STANDARD CELLS. By F. A. Wolff and C. E. Waters. INTRODUCTION. The important role now played by the standard cell in both tech- nical and scientific work, and the possibility of its adoption as a primary standard of electromotive force, have led in recent years to a considerable number of investigations concerning its reproduci- bility and constancy. The character of these investigations and the results obtained will, however, be better understood after a brief review of the previous work on the subject. The need of a definite and universal system of electrical units was early recognized. Owing to its preponderating importance in the earlier applications of electricity, the unit of resistance naturally received first attention. The committee on electrical standards appointed by the British Association in 1861 recommended the adoption of the C. G. S. electromagnetic system together with a practical system defined as decimal multiples and submultiples of the C. G. S. units. In addition, its labors led to the construction of concrete standards of resistance in the form of coils of platinum- 9 silver of special design adjusted to represent io C. G. S. units as determined by a series of absolute measurements. The definition of unit current and electromotive force in terms of the C. G. S. units long met every requirement, particularly as currents were generally measured by the aid of the tangent galvanometer, while electromotive forces were generally measured in terms of the electromotive force of the Daniell cell. In 1872 Latimer Clark called to the attention of the British Asso- ciation committee the superiority of the cell which now bears his 2 Bulletin of the Bureau of Standards.
