The sample pretreatment method of solid phase extraction (SPE) currently used by the Haozhuang (LNB) brand solid phase extraction device produced and developed by Shanghai Haozhuang Instrument Co., Ltd. is characterized by high efficiency, speed, convenience and high selectivity. Shanghai Haozhuang Instrument Co., Ltd.'s newly developed Haozhuang (LNB) brand solid phase extraction device SPE vacuum device is an important part of Haozhuang LNB-SPE method. Can process 12 or 24 samples at the same time, 12 and 24 are divided into Haozhuang unified control and Haozhuang independent control of each hole type, 12 and 24 bits are equipped with Haozhuang pressure gauge, and the other 12 , 24-bit independent control Each hole type is equipped with 12 or 24 flow control valves, which is more convenient for your operation. With its unique rotating top cover, it is easy to switch between each step of LNBSPE to collect the required components. A Haozhuang solid phase extraction device LNB vacuum device combined with high performance liquid chromatography (HPLC) separation is used. Examples of application of bile acids in human serum. The design and application of the vacuum of the solid phase extraction device, see below for details: â— Anti-cross pollution, anti-atomization vacuum tank design, simple and fast operation. â— No phase separation operation is easy to collect analyte components and can handle small volume samples. â— The solid phase extraction device can be equipped with a large-capacity collection container, which can process samples in batches or individually. â— Vacuum groove is formed by special hard glass mold, and its uniform wall thickness can withstand high negative pressure above -0.085Mpa. â— The extraction column tray is made of special polymer material, which is beautiful and corrosion-resistant and does not deform under long-term use under high pressure. â— The internal test tube rack is made of PTFE so it has high corrosion resistance.
