摘要： The invention relates to a method for analysing a blend of two or more hydrocarbon feed streams such as crude oils. These crude oils are blended in a facility such as a refinery. The method assesses the compatibility of a hydrocarbon feed in a blend to calculate the blend stability such that organic deposition is minimised. The method uses all of a plurality of hydrocarbon feeds to be blended for analysis. The method either selects a neat hydrocarbon feed, from a plurality of the hydrocarbon feeds included in a blend, as a titrant, wherein the or each other hydrocarbon in the hydrocarbon feed are used to make a pseudo-blend and titrating the pseudo-blend with said selected neat hydrocarbon feed for a plurality of different blend ratios. Alternatively the method involves preparing a reference hydrocarbon and making a blend from the plurality of hydrocarbon feeds and titrating the blend with the reference hydrocarbon. Measurements associated with the change in characteristics of the titrated blend are made and data recorded. The method then calculates, using said data, the stability of the blend.

摘要： A use composition monitor determines the concentration of peracid and/or peroxide in a use composition using a kinetic assay procedure. A sample mixture containing a sample of the use composition, a diluent and at least one reagent is prepared and analyzed using, for example, an optical detector. A reduced-turbulence optical detector can be used to improve collected response data. A reduced-turbulence optical detector can include a cell body disposed about a length of transparent tubing. The cell body positions one or more emitter/receiver pairs about the transparent tubing. Thus, tube junctions are eliminated and sample flow within the tube is substantially turbulence free.

摘要： A small liquid sample (24) to be tested is contained within an annulus (18) on the upper surface (14) of a substrate (12). In one embodiment, a reagent diffuses into the sample through a membrane (28) in a junction hole (26), the junction hole connecting upper (14) and lower (16) surfaces of the substrate. Optical measuring equipment (70, 72) detects a measurable change in an optical property of the sample. In an alternate embodiment, a flow of gas (30), directed at the small liquid sample (24), causes the sample to flow in a controlled manner over the surface of an electrode (20), disposed on the substrate surface (14). In another alternate embodiment, a special averaging electrode (20) is disposed in a non-homogeneous sample (24). Highly reproducible and accurate hydrodynamic electrochemical studies and analyses of microliter size samples are thus achievable, without the need for moving mechanical parts.

摘要： A method and system achieving the results of a conventional titration without the need to chemically dilute a sample. Such a result is accomplished by providing a plurality of calibration standards, each containing a different known concentration of a visualizable material. The visualizable material contained within each calibration standard is then visualized (the parameters of the visualization forming a setting). The visualization is then altered by adjusting at least one parameter of the visualization until the point where the visualizable material within each calibration standard can no longer be visualized within the solution. The visualizable material within a sample solution having an Unknown concentration of the visualizable material is then visualized using settings corresponding to the plurality of calibration standards to generate a number of modified visualizations. (Each modified visualization corresponds to the concentration of the standard to which it relates). The modified visualization at which point the visualizable material can no longer be visualized is then correlated with the corresponding concentration, to determine the titration of the sample solution.
