摘要： The invention provides a method for the determination of the phase change characteristics of a hazardous material, the method comprising optically recording images of a sample of the material and objectively evaluating the images. The phase change characteristics generally relate to a solid/liquid or liquid/solid phase change, and the method finds particular application in the determination of the crystallisation points of hazardous materials, most particularly radioactive materials. The images are typically recorded by means of a camera, and evaluated using a computer, which is able to objectively determine the point at which a phase change is first seen to occur, and thereby provide accurate, reliable and objective data.

摘要： A method for detecting particles in a fluid involves passing any ultrasonic signal through the fluid. A Fast Fourier Transform analysis is performed on the received signal, to determine a characteristic frequency of the fluid where the amplitude is greatest. Both the amplitude of FFT spectrum at the characteristic frequency and the time-domain amplitude are monitored. A drop either in the amplitude of the FFT spectrum at the characteristic frequency or the time-domain amplitude indicates the appearance of particles in the fluid.

摘要： In the method of the invention for crystallization of proteins and the like, test substances prepared by mixing a sample of a protein and the like and reagents which promote the crystallization of the sample are put into test-substance wells of containers, such as microplates, and transferred to an analysis process, such as an X-ray crystal structural analysis, to perform an information analysis of the sample. This method includes the steps of: setting a plurality of standard images of progress stages of the test substances, such as crystal formation, as images in uncompleted crystallization regions and images in crystallization regions permitting an analysis; comparing data on the plurality of standard images with fetched image data during the progress of crystallization of the test substances thereby to make a judgment; selecting only test substances having fetched image data in perfect or close agreement with the images in crystallization regions permitting an analysis; and transferring a container containing the test substances to the analysis process. In the above-described method, a mark to indicate the selection is automatically put to the container containing the test substances which are selected by comparing data on the plurality of standard images with the fetched image data to make a judgment. The method of the invention includes a crystallization robot, which prepares test substances by mixing a sample of a protein and the like and reagents which promote the crystallization of the sample in test-substance wells of containers such as microplates; a stocker housing portion, which includes a plurality of shelves which temporarily store the containers containing the test substances in such a manner as to permit the mounting and dismounting thereof; an image processor, which performs image processing of the test samples in the containers stored in the stocker housing portion thereby to grasp the condition of crystallization; a stocker robot, which performs the mounting and dismounting of the containers in the stocker housing portion; and a stage robot, which performs the transit of the containers from the stocker robot and the transfer and supply of the containers to the crystallization robot and the image processor.

摘要： A crystallizer control method and apparatus that generate control signals to manipulated process parameters on the basis of on-line information derived from the measurement of the crystal population in a selected size range in the crystallizer slurry. According to one embodiment of the invention, a particle counter probe is immersed directly into the fines removal circuit of the crystallizer for on-line measurement of crystal population in the 16 to 32 micron size range. The data so collected are then used directly in a standard proportional controller apparatus to manipulate certain operating parameters, such as fines removal rate and feed rate, to effect the desired result. Applying this model-independent control method to a KCl crystallizer, the steady-state conditions of the crystal size distributions were reestablished after an upset in approximately half the time required when no control was applied. The maximum perturbation of the performance index in the controlled case was approximately 65 percent of the magnitude registered without control. The perturbation of the crystal population in the 16-32 micron range was approximately half of that seen without control.

摘要： A process for determining the degree of saturation of a solution comprising a solvent and a compound of limited solubility which involves the steps of (1) diluting a feed solution of the compound of limited solubility, (2) passing a sample of the diluted feed solution through a bed of a solid solution of the compound and a tracer in which the tracer is intrinsically incorporated into the crystal structure of the compound, so that the diluted feed solution being tested becomes saturated with the compound by dissolution of a portion of the solid solution in the bed, (3) measuring the concentration of the tracer in the sample after passage through the bed of solid solution, thus measuring the amount of the compound dissolved from the solid solution to saturate the diluted feed solution, and (4) determining the degree of saturation of the compound in the feed solution from the measured values.

摘要： A method for determining the onset of nucleation wherein a zone of a translucent fluid in which crystals may be formed is illuminated by a beam of light. When crystallization commences the crystals in the illuminated zone reflect and scatter light. Some of the scattered light is collected and transmitted to a light sensitive detector operable to generate a signal indicative of nucleation. Upon detection of nucleation either manual or automatic procedures may be instituted to modify the crystallization process in an appropriate manner.
