摘要： A process for simultaneous assay of chlorides and sulfides by low pressure ion exclusion chromatography is provided, and in said process an analytic apparatus comprising a sampling valve, a sampling loop, an ion exclusion column and an analytic detection flow path is used, and said process comprises the following steps: (1) in the analytic detection flow path, the mixture of developer R1 and developer R2 mixes with Eluent C and then enters into a reactor, and the mixing is continued under heating. The resulting mixture flows into the optical flow cell and a baseline is mapped accordingly; (2) a testing sample S flows into the sampling loop through a sample flow path and the sampling valve, and under the drive of Eluent C, flows into the ion exclusion column from the sampling loop, and enters into the analytic detection flow path through the ion exclusion column; developer R1 and developer R2 each enter into the analytic detection flow path through respective developer flow path and mix with each other in the analytic detection flow path. The mixture of developer R1 and developer R2 mixes with the Eluent C carrying the testing sample and then enters into the reactor, and the mixing is continued under heating and a reaction takes place. The reacted mixture flows into the optical flow cell and a spectrogram of the testing sample is mapped accordingly.

摘要： The present invention is a rapid method of determining the concentration of the major components in a chemical stream. The present invention is also a simple, low cost, device of determining the in-situ concentration of the major components in a chemical stream. In particular, the present invention provides a useful method for simultaneously determining the concentrations of sodium hydroxide, sodium sulfide and sodium carbonate in aqueous kraft pulping liquors through use of an attenuated total reflectance (ATR) tunnel flow cell or optical probe capable of producing a ultraviolet absorbency spectrum over a wavelength of 190 to 300 nm. In addition, the present invention eliminates the need for manual sampling and dilution previously required to generate analyzable samples. The inventive method can be used in Kraft pulping operations to control white liquor causticizing efficiency, sulfate reduction efficiency in green liquor, oxidation efficiency for oxidized white liquor and the active and effective alkali charge to kraft pulping operations.

摘要： A process and apparatus are disclosed for the detection and measurement of sulfur in both organic and inorganic sulfur-containing compounds. The process includes admixing a sample including a sulfur-containing compound with oxygen, and then exposing the mixture to a source of combustion causing heat in the presence of a combustion supporting reducing agent at a combustion site. The resulting gaseous combustion products are vacuum extracted from the combustion site, and then directed into a darkened low pressure chamber. The combustion products in the low pressure chamber are then contacted with ozone, with the result that the sulfur combustion products are converted to chemiluminescent sulfur dioxide. The emitted chemiluminescence is then detected, and may be measured to provide a quantitative indication of the amount of sulfur in the original sample. The preferred source of oxygen is air, the preferred form of combustion heat is a flame, and the preferred form of reducing agent is hydrogen gas.

摘要： Phenyl substituted 2-thiazolyl tetrazolium salt compounds characterized by a reflectance spectrum exhibiting an extended plateau above about 600-650 nm. Such compounds are useful as chromogenic indicators for reducing substances such as NADH.

摘要： This invention relates to a process for the selective determination of theoncentration of a substance dissolved in a solvent by means of an osmosis cell. The osmosis cell according to the invention contains a substance not contained in the solution to be tested, which is either practically insoluble or is impermeable for the membrane. This substance reacts chemically with the substance permeating into the osmosis cell, with a product resulting from it in the cell or with a product resulting from the substance in the solution to be tested and permeating into the cell. Reaction products are thereby formed which produce a pressure in the osmosis cell, which is different from the osmotic pressure of the chemically converted portion of the substance. A pressure increase thereby occurs in the cell, from which the concentration of the substance in the solution to be tested can be determined on the basis of standard values.
