Introduction: Solid-phase extraction is a kind of sample pretreatment technology developed in recent years. It is developed from the combination of liquid-solid extraction and column liquid chromatography. It is mainly used for the separation, purification and concentration of samples. Compared with traditional liquid-liquid extraction, Many problems are avoided, such as easy emulsification, incomplete phase separation, low quantitative analytical recovery, expensive fragile glassware, and large amounts of organic waste. Solid-phase extraction more effectively separates the analyte of interest from interfering components, which can increase the purity and recovery of the target analyte, reduce relative bias, improve reproducibility, and facilitate more accurate qualitative and quantitative analysis of the target analyte. . Solid-phase extraction technology can conveniently process multiple samples at the same time, greatly reducing the amount of sample pretreatment and operating time, effectively improving the efficiency of the work, with simple, accurate, time-saving, labor-saving, environmental protection and other characteristics. BT-158 semi-automatic solid phase extraction instrument can be used in various food safety testing, agricultural product residue monitoring, medical and health, environmental protection, commodity inspection, tap water and chemical production laboratory. In the process of sample processing, the column flow rate of various solutions is accurately controlled in an automatic manner, and at the same time, positive pressure elution, large-volume continuous injection and timing functions are used to ensure the recovery and purity of the target analytes, reduce relative deviations, and avoid Cross-contamination between samples allows multiple samples to be processed at the same time, further improving work efficiency, and providing easy operation and maintenance. Features: 1. Single-channel flow rate 0.01~10.85ml/min, supporting large-volume injection and positive pressure elution to avoid cross-contamination; 2. Stepless automatic operation, large-screen LCD display, touch screen and button compatible operation, ergonomics design; 3, chassis phosphating and multi-layer epoxy spray coating; integrated equipment makes operation easier and faster; 4, equipped with Ya source extraction technology software modules; a variety of output methods, optional connection to the computer operation; 5, multi-channel, small column joints acid, alkali, organic solvents, oxidant corrosion; 6, the use of high-precision motor automatic technology, low energy consumption, precise speed control; 7. The automatic pump tube adopts the American original long-life tubing; 8, simple operation, single operation can be carried out at the same time the processing of 1 to 8 samples, greatly improve work efficiency; 9, the consistency of the extraction speed is good, the control and adjustment are convenient; the sealing is good and the stability is strong 10.
