Principles of High-Frequency Titrimetry

Properties of the Contactless Impedance Detector with Insulated Wire Electrodes Placed Inside the Flowing Liquid Stream

“…The cell generally represents the input impedance, Z i , of the amplifier and can be described by the simplified electric equivalent circuit [15] which is commonly used for the description of the capacitive contactless conductivity cells (Fig. 2B).…”

The use of a radio-frequency oscillator in student analysis

“…It has been shown that the over-all conductance anil capacitance are, for dilute ionic solutions, unique functions of the dielectric constant of the solvent and of the ordinary low-frequency conductance of the solution. An equation for the r-f. conductance, G, which would be measured across the terminals A B (Figure 3) has been given by Reilley and McCurdy (3) as:…”

“…Hall (f), by Blaedel, Malmstadt, Petitjean, and Anderson (2) or by transfer plots first used by Reilley and McCurdy (3). The construction of a transfer plot will be described later.…”

“…The procedure was as described by Hall (6), with the addition of a transfer plot, as described by Reilley and McCurdy (3).…”

Applicability of megacycle frequency oscillator circuits to reaction rate measurement

“…(1) as indicated in fig. 3, the data for which can be obtained by the use of a twin-T impedance measuring circuit.109 11 The latter effectively measures the equivalent parallel capacity and high-frequency conductance separately as well as independently of other circuit components. The values of the conductance at…”
