Controlled-Potential Polarographic Polarizing Unit with Electronic Scan and Linear Residual Current Compensation

Polarography in sulfolane and reference of potentials in sulfolane and other nonaqueous solvents to the water scale

“…The instrument described here is a versatile polarograph having capabilities of previous ORNL DC polarographs (1)(2)(3), but with improved performance, functional and operational features not included in previous instruments, and low maintenance requirements and reliability resulting from the use of solid-state operational amplifiers. The potentiostat is capable of delivering 20 mA at 10 volts to the polarographic cell.…”

Determination of molybdenum by controlled-potential coulometry. Application to the analysis of molybdenum-tungsten-rhenium alloys

“…Polarographic measurements were made with both a controlled-potential, fast-sweep differential polarograph (13), and an ORNL Model Q-1988-ES controlled-potential, dc derivative polarograph (14,15).…”

Differential constant-current potentiometry for analysis by kinetics

“…The past decade has witnessed this field develop from infancy to a state of incipient maturity as a result of rapid evolution of knowledge in three principal areas: instrumental techniques, usable solvents and appropriate schemes for their purification, and electrode reaction mechanisms. The measurement problems attending the high resistance characterizing most aprotic solvent-supporting electrolyte systems (1,2) have been overcome to a large extent by the development of potentiostats and galvanostats which permit automatic potential and current control with threeelectrode cell configurations (3)(4)(5)(6)(7)(8)(9)(10). This development began in the late 1950's with the efforts of Booman (3), DeFord (3, and Kelley and coworkers (6,7).…”
