摘要： The present invention provides an apparatus for the mixing or dilution of chemicals from one more sources that have been analyzed using laboratory analysis or an insitu-analyzer for concentration or molarity. The chemical is then transferred to a series of precisely calibrated vessels each of have a volume 10% of the next vessel. For example the main vessel may be 1 L in volume and the second vessel is 0.1 L in volume, the third is 0.01 L in volume and the fourth is 0.001 L in volume. The present system utilizes these two or more metered vessels which are connected to bulk chemical sources via intake lines. Each metered vessel contains an overflow tube, which drains any excess chemical by gravity flow from the metered vessel so as to adjust the chemical amount to a pre-calibrated desired level. As the chemicals exit the angle pipes, sensors located at the end of the overflow tube sense the chemical being discharged and trigger the feed pump and valve to shut off, whereby the excess chemicals will continue to drain out until the chemical levels reach the same level as the vent port of the pipe attached to the metered vessels. The excess chemicals are then drained into a recovery vessel which then can be transferred back to the bulk sources via a feed pump or pressure mechanism. The chemicals in the calibrated vessels are then dispensed by gravity lines to the mix tank vessel for mixing and subsequently delivered to a qualification vessel which may be verified using titration or online Ion Chromatography.

摘要： A method for measuring an evolution rate of a gas from a sample includes equilibrating a sample with an alkaline solution and a pH indicator and permitting the alkaline solution to absorb formed carbon dioxide in an enclosed headspace. From the pH indicator at equilibrium is determined a time increment at which an increment of the alkaline solution is consumed by the CO2. Carbon dioxide evolution rate is calculated from the time increment, the volume increment, and the alkaline solution concentration. A device for performing this measurement includes a sample vial and a reaction chamber having an opening adapted for mating with a sample vial opening and an opening for receiving the solution. The reaction chamber is dimensioned for equilibrating the sample with the alkaline solution and for determining the time increment required for an increment of the alkaline solution to be consumed by CO2.

摘要： Chemical species (e.g., metaborate, carbonate, hydroxide and sulfide) in a boron-containing alkaline wood pulping liquor sample are determined quantitatively by (i) subjecting a first aliquot portion of the sample to a primary acid titration analysis to derive multiple equivalence points at different respective pH values; (ii) subjecting a second aliquot portion of the sample to an analysis to determine the quantitative presence of boron or sulfide ions therein, and then (iii) determining the quantitative presence in the sample of at least one of the chemical species. Wood pulping parameters may thus be determined on the basis of the quantitative presence of the chemical species to assist in process and/or quality control of the wood pulping operation. For example, the sample may be analyzed for boron content using colorimetry or atomic spectroscopy and/or analyzed for sulfide ion content using a secondary silver sulfide precipitation titration analysis, each of which may be conducted substantially simultaneously with the primary acid titration analysis.

摘要： A method of determining the moisture content in wood in which a sample of the wood being tested is first frozen with liquid nitrogen, homogenized and a test sample is placed in a Karl Fischer titration system. The test sample is placed into a solvent solution and the reagent or titrant is progressively added to the solvent solution as the presence of moisture from the wood sample is detected. Once the moisture has been titrated from the solution the moisture content of the wood is determined based upon the amount of reagent dispensed into the titration solution.
