Polarographic Determination of Dissolved Oxygen. Study of Drop Time with Rapid-Dropping Mercury Electrode

“…Effect of Stirring. Movement of the solution has little effect on the current produced when the drop time is sufficiently small { , 13). This Potassium chloride solution, 0.0IN, containing 0.257 mmole of oxygen per liter be used for analyzing flowing solutions and for amperometric titrations where the solution can be continually purged with nitrogen and agitated.…”

Cell for continuous analysis in flowing solutions with the rapidly dropping mercury electrode

“…In the last decades, there have been several polarographic approaches to the problem of continuous analysis in flowing solutions (1)(2)(3)(4)(5)(6)(7)(8)(9)(10)(11)(12)(13)(14)(15). For this purpose, both the conventional dropping mercury electrode (DME) (2-8, 11, 12, 14, 15) and the rapidly dropping mercury electrode (RDME) (9,10,13) have been used. The RDME differs from the DME in the shorter dropping time (t = 1.5-0.1 sec).…”

“…The RDME differs from the DME in the shorter dropping time (t = 1.5-0.1 sec). It can be obtained with L-shaped capillaries (16), horizontally placed capillaries (9), or large bore capillaries (10). In conjunction with the use of DME and RDME as detectors in flowing solutions, special cells have been developed (2,3,(5)(6)(7)(8)10,12,13).…”
