Solid phase extraction is used in the fields of environmental water quality analysis, food safety analysis, judicial identification analysis, drug analysis, bioengineering and other fields.
1. Analysis of pesticide residues: water, soil, food, etc.
2. Environmental analysis: such as trace amounts of copper in water, pesticide chalk interfering substances, organic matter in the air, etc.
3. Food analysis: vegetables, fruits, cereals, oils, fish, etc.
4. Biopharmaceutical analysis: serum, blood, plasma, urine, etc.
5. Drink analysis: juice, wine, etc.
6. Veterinary drug residue analysis

Instrument introduction: HSE The solid phase extraction device consists of a pneumatic chamber, a collection bottle and an extraction column connection. It is mainly used for pretreatment of liquid samples, extracting semi-volatile or nonvolatile compounds therein, or removing impurities that interfere with separation and analysis in the sample, and can also be used to treat solid samples that can be pre-dissolved into solvents. Compared with traditional liquid-liquid extraction methods, the recovery rate of analytes can be improved and the analytes can be separated from interfering components more effectively, shortening the sample pretreatment process, simple operation, time-saving and labor-saving, and widely used in medicine, food, environmental protection, commodity inspection, chemical engineering and other fields.

Main features 
1.High recovery and high enrichment multiples；  
2.Simple, fast and easy to automate；  
3.Design of anti-cross-contamination and anti-atomization vacuum tank；  
4.Good sealing and high consistency；  
5.Phaseless separation operation, easy collection of analyte combinations, and can handle small volume samples；  
6.Can be equipped with large-capacity sampler, fast concentration and drying device, and batch processing of samples；  
7.Except for the gas chamber and collection bottle, the use of extra hard thickened glass, all other components are made of tetrafluoro and 316 stainless steel, which has strong corrosion resistance.

Purchase Guide:

12The main difference between the square and round solid-phase extractors of pores is that the waste liquid is collected in different ways. The round ones save space and can be equipped with a blow-drying device, which is suitable for experiments where the leaching solvent needs to be blown dry. The square solid phase can display the vacuum degree, so the accuracy of the liquid flow rate in each experiment can be ensured, that is, the experiment repeatability can be improved. Suitable for experiments with strict requirements on experimental repetition. If the processing volume is relatively large, 24-well solid phase extraction can be used. Due to the different structures of the two solid phase extraction devices, when 24-well is selected, the square solid phase is more practical.
