The invention provides an automatic sample adding and uniform mixing device for pretreatment of the spectrophotometric method, which mainly comprises a base, a sample adding and sampling device for adding a buffering agent and sampling a sample cup which is added with the buffering agent and is uniformly mixed, a transmission and uniform mixing device for transmitting the sample cup and a cuvette, a weighing device for measuring the overall weight of the sample cup, a reagent adding device used for adding experimental reagents, a cleaning device used for cleaning the sampling needle and the reagent needle, and a control system and a control terminal that are used for controlling the devices. The main existence form of the control terminal is that control software runs in a network computer. The sample adding and sampling device, the transmission and uniform mixing device, the weighing device, the reagent adding device, the cleaning device, the control system and the control terminal are used in cooperation, automatic sample adding of cuvettes of a pretreatment part in the spectrophotometric method is achieved, the efficiency and accuracy are high, errors are small, the cost of manual sample adding of professional experimenters is reduced, and the cost is saved.
Description
technical field [0001] The invention mainly relates to the technical field of detection equipment, in particular to an automatic sample adding and mixing device for pretreatment of spectrophotometry. Background technique [0002] Detection technology is one of the essential means of scientific experiments. The commonly used ultraviolet spectrophotometry is a qualitative, quantitative and structural analysis method established according to the absorption characteristics of material molecules on electromagnetic waves of different wavelengths. Spectrophotometer as a An optical detection device is often used to detect and analyze the content of each element in a sample. [0003] Spectrophotometry is divided into two parts: pre-processing and detection; the workload of the pre-processing part accounts for about 80% of the whole process. However, in the spectrophotometric detection experiment, it is still necessary to complete the sample weighing and sample addition through manual...
