The automatic solid phase extraction device independently developed by Shanghai Xinzhuang Instrument Co., Ltd. is divided into 12 holes and 24 holes for unified control, and each hole device is independently controlled. Solid-Phase Extraction (SPE) is a widely used and popular sample preparation technology that uses a solid adsorbent to adsorb a target compound in a sample, separate it from the matrix and interfering compounds of the sample, and then The eluent is then eluted or desorbed by heating to achieve the purpose of separating and enriching the target compound. Based on the traditional liquid-liquid extraction (LLE), it uses the similar principle of similarity between substances and combines the basic knowledge of liquid chromatography (HPLC) and gas chromatography (GC) stationary phases. In the solid phase extraction process, the solid relative analyte is more attractive than the sample mother liquor. When the sample passes through the SPE column, the analyte is adsorbed on the solid surface, and the other components pass through the column with the sample mother liquor, and finally the appropriate solvent will be used. It elutes. SPE itself can be divided into four types according to its principle: reverse SPE (RP-SPE), forward (NP-SPE), ion exchange SPE (IE-SPE), and adsorption SPE (Absorption). In most cases, solid phase extraction is used to treat liquid samples for extraction, concentration, and purification of volatile and semi-volatile compounds in a sample; when needed for a solid sample, the solid sample must first be treated as a liquid. When the number of individual SPE treatments increases, the timeliness of the analyst becomes frequent and complicated. The human error greatly affects the reproducibility of the processed samples, which is not conducive to the quantitative and qualitative work of the analysis results. The company introduced the United States imported technical support, SPE multi-tube vacuum solid phase extraction device (Vacuum Manifold) in response to the response, the company's DG series solid phase extraction device can simultaneously process multiple SPE work items in batches, and will not cross infection, closed The integrated anti-atomization observation bin makes your SPE work clear and clear. Shanghai Xinzhuang not only developed low-temperature constant temperature instruments, ultrasonic instruments, box-type instruments, microbial instruments, ice-making refrigeration instruments, laboratory supporting instruments, but also gradually formed a product pattern of various scientific instrument technology reserve products. .
