    摘要: The invention relates to analytical instrument engineering, in particular to spectroscopy. The inventive method for measuring spectroscopic properties of bulk products consists in portionwisely supplying a sample in a measurement area. In order to fully fill said measurement area, several portions (at least two) are loaded and alternately placed substantially in different fields of the horizontal section of the measurement area in such a way that the uniformed distribution and the permanent density of the product in the area of measurement are provided. Afterwards, the spectroscopic properties of the sample are recorded in a standstill and the sample is removed from the area of measurement. The inventive device for measuring spectroscopic properties of bulk products comprises a feeding hopper, an input (receiving) opening, a batch loading unit which is provided with means for successively and uniformly distributing the product alternately in the different fields of the horizontal section of the area of measurement, a measuring unit, a unit for closing the area of measurement, an output (unloading) opening and a discharge hopper. Said invention makes it possible to ensure the high uniformity and permanent density of the product in the area of measurement during the measurement of the spectroscopic characteristics of the bulk products.

    摘要: A method and system for automatically analyzing the presence of an analyte in a liquid specimen of biological origin are described. The liquid specimen is added to a testing substrate that has a receptor immobilized on a portion of its surface. If analyte is present in the specimen, it will specifically bind to the receptor. A labeled reagent is added to the testing substrate which will bind to the analyte, if present, and generate a color on the testing substrate. The testing substrate is then illuminated and, using electronic equipment, a digital image of its surface is acquired and automatically scanned to locate an area that has the highest color density, which corresponds to the presence of labeled reagent. A measurement of color density, corresponding to pixels per unit area, is generated. An area peripheral to the area of highest color density, which represents background density, is also located and a measured. The presence or absence of analyte in the liquid sample is determined by adjusting the measurement of labeled reagent with the background density measurement in accordance with a predefined mathematical function. In some cases, the result of the test will be interpreted as a binary, positive/negative result according to whether the measurement taken is above or below a given threshold. In other cases, a continuous range of values may be generated from different samples that correspond to the concentration of the analyte present in each tested sample.
