2results about How to "Reduce cost burden" patented technology

The application discloses an immune detection method for accurately quantifying structural analogues and application thereof. The immune detection method can realize accurate, intuitive and rapid identification and quantification of target analytes by combining wide-spectrum antibodies and specific antibodies to recognize structural analogues and by establishing a three-dimensional curved surface model through a multilayer perception machine model, and can solve the problem of false positive results in the detection process due to the high structural similarity between a certain target analyte and another substance in the immune analysis method, especially for analytes with indistinctive characteristic structures and cross substances, which are often difficult to prepare high-specificity antibodies. The immune detection method is simple to operate, does not require experimental personnel to take multiple verification measures, and greatly reduces the cost burden of detection. The application has great significance and broad application prospect for improving the accuracy of rapid detection of residual substances in food.

The disclosed apparatus for mixing and supplying chemicals used for semiconductor processes according to the present application includes: raw chemical supply lines for externally supplying chemicals; and a mixing line for receiving the chemicals from the raw chemical supply lines to produce a chemical mixture; wherein one end of each of the raw chemical supply lines is connected to a chemical storage tank in which the chemicals are stored, and a chemical flow controller for controlling the flow rate of the chemicals is installed in each of the raw chemical supply lines, and the chemical flow controllers installed in each of the raw chemical supply lines are controlled in multiple channels using one controller, and the flow rate of each of the chemicals is preset corresponding to a mixing ratio of the chemicals and stored as a preset value, and when the chemicals are supplied for mixing, the flow rates of the chemicals are simultaneously controlled using the preset values corresponding to the mixing ratio, which are previously stored.
