Solid phase extraction (SPE) is a widely used and increasingly popular sample pretreatment technique, which is based on traditional liquid-liquid extraction (LLE) and combines the similar solubility mechanism of substance interactions with the widely used HPLC The basic knowledge of fixed phase in GC has gradually developed. SPE has the characteristics of low organic solvent usage, convenience, safety, and high efficiency. SPE can be divided into four types based on their similar solubility mechanisms: reverse phase SPE, normal phase SPE, ion exchange SPE, and adsorption SPE. SPE is mostly used to process liquid samples, extract, concentrate, and purify semi volatile and non-volatile compounds, and can also be used for solid samples, but must first be processed into liquid. At present, it is mainly used in the analysis of organic substances such as polycyclic aromatic hydrocarbons (PAHs) and polychlorinated biphenyls (PCBs) in water, pesticide and herbicide residue analysis in fruits, vegetables and food, antibiotic analysis, clinical drug analysis, etc. in China. The SPE device consists of SPE columns and accessories. The SPE column consists of three parts: column tube, sintering pad, and packing. SPE accessories generally include vacuum systems, vacuum pumps, blow drying devices, inert gas sources, large capacity samplers, and buffer bottles. Kanglin recommends using Supelco's solid phase extraction (SPE) device from the United States. Typical applications ● Biological fluid analysis, mainly including: serum, plasma, blood, urine and intercellular matter ● Milk treatment, Baijiu, beer and beverage, fruit juice ● Analysis and monitoring of drinking water, groundwater and sewage ● Volatile oil, plant tissue, fruits, vegetables and grains ● Liquid drug samples, soil and sediment ● Meat, fish or other animal tissues, tablets and other solid drugs

● Can be equipped with large capacity samplers, rapid concentration and drying devices, batch processing samples ● Made of durable and anti-interference polytetrafluoroethylene material ● SPE small column has stable quality, high sample recovery rate, and good precision
