摘要： A combination of a measuring sensor and protector having a measuring sensor with a housing and having an elongated cup-like protective pipe engaged with the housing. The pipe has a bottom having a convex shape with an inlet opening. The pipe also has at least one outlet opening spaced away from the bottom. A deflector extends inward from the pipe at an acute angle relative to a longitudinal axis of the pipe and away from the bottom so that when gas flows longitudinally within the pipe from the inlet opening, the gas is deflected by the deflector to flow around the deflector to the at least one outlet opening. The bottom also has a boss-like bulging portion projecting outward to form the inlet opening so as to reduce contamination of the measuring element by preventing solid particles in the gas from entering inside the pipe.

摘要： An apparatus and method are disclosed for the continuous monitoring of pH in a fluid stream flowing at a low volumetric flow rate. The stream is directed through an enclosed conduit with a glass electrode sealed therein. The conduit wall facing the electrode has contour approximately complementary in shape to the sensing surface of the electrode with a narrow gap between the opposing surfaces through which the fluid passes, forcing rapid and uniform flow of the fluid over the electrode surface. Continuous operation is thereby permitted for extended time periods without substantial fouling of the surfaces.

摘要： An electrode that is specific for the isocyanurate ion, and capable of rapid determination of the free isocyanurate ion activity directly in solution uses as its sensing element a platinum wire covered with a polyvinyl chloride membrane. The membrane is plasticized with a solution of a quaternary ammonium salt of isocyanuric acid. When this electrode and a commercial reference electrode are immersed in a solution containing the isocyanurate ion, a differential voltage proportional to the isocyanurate ion concentration is generated which is detected by a pH meter.

摘要： A method for investigating and controlling a two-phase liquid system, and for determining the partition factor of a substance between two substantially immiscible liquids. The liquids are intimately mixed in a mixing zone in the presence of the substance to be tested, said substance being introduced therein in any suitable manner. The liquids are separated into their two phases, the separator having one outlet for each phase. The individual phases are conducted to corresponding testing stations where the concentration of said substance in each phase is measured.
