Shanghai Haozhuang Instrument Co., Ltd. has developed the LNB brand solid phase extraction device, which is energy-saving and environmentally friendly, leading the country. Professional manufacturing is more secure and affordable. Overview of solid phase extraction equipment: As a sample preparation technology, solid phase extraction has been more and more widely used in the laboratory. It utilizes the poor ability of the analyte to be adsorbed in different media to purify the target substance, effectively separating the target substance from the interfering components, greatly enhancing the ability to detect analytes, especially trace analytes, and improving the sample to be tested Recovery rate. Such products are widely used in many fields such as pesticide detection, food analysis, medicine, and commodity inspection.
The principle and application of the solid phase extraction device: The solid phase extraction device uses a solid adsorbent to adsorb the target compound in the liquid sample, separate it from the sample matrix and interfering compounds, and then elute with the eluent or heat desorption to achieve separation And the purpose of enriching the target compounds (ie sample separation, purification and enrichment), the purpose is to reduce sample matrix interference and improve detection sensitivity, which is applied to various food safety tests, agricultural product residue monitoring, medicine and health, environmental protection, commodities Inspection, tap water and chemical production laboratories. The main characteristics of the solid phase extraction device: 1. The whole machine is made of transparent organic glass and has strong corrosion resistance. 2. Each channel is equipped with an inlet regulating valve, which can adjust the flow rate according to the test requirements. Good sealing and high consistency; 3. Simple operation, fast and easy to realize automation; 4. Design of anti-cross contamination and anti-atomization vacuum tank; 5. The solid phase extraction instrument is evenly pressurized everywhere, good air tightness and stability Sexuality. 6. The internal test tube rack of the product is made of PTFE, so it has high corrosion resistance. 7. The vacuum tank has uniform wall thickness, so it can withstand high negative pressure above -0.096Mpa. Technical characteristics of solid phase extraction device: 1. Accurate speed control, single channel flow rate 0.01-7ml / min, support large volume injection and positive pressure elution, avoid cross contamination; 2. Corrosion-resistant top plate, chassis phosphating and multi-layer ring Oxygen resin spraying treatment; 3. The structure of the chassis is convenient for maintenance; 4. Multi-channel, the small column joint is resistant to acid, alkali, organic solvents, and oxidants; 5. The operation is simple, and the single-person operation can process 1-8 samples at the same time, greatly Improve working efficiency; 6. Good extraction speed consistency and easy control adjustment; 7. Good sealing, strong stability, good linear relationship between speed and flow rate.
