Shanghai Solid Phase Extraction Instrument Sample Extraction Device

Technical parameters:

Model: XSPE-12(24)

Number of processed samples: 12 (24) digits

　　Shanghai Solid Phase Extraction InstrumentAccessories generally include vacuum systems, drying devices, large capacity samplers, and buffer bottles (all of which need to be purchased separately).

　　Main features:

1. Each channel is equipped with an independent regulating valve, which is easy to control, accurately controls the flow rate, and is durable;

2. Equipped with a pressure gauge for easy observation;

3. The height of the test tube rack can be adjusted to meet different needs;

4. Except for the use of extra hard and thick glass in the air chamber, all other components are made of PTFE material, which has strong corrosion resistance;

5. Design of anti cross contamination and anti atomization vacuum chamber;

6. XSPE small column has stable quality, high sample recovery rate, good precision, easy collection of analyte combinations, and can handle small volume samples;

7. It can be equipped with a large capacity collector, a rapid concentration and drying device, and can process samples in batches. The large capacity collector can directly transfer low viscosity samples from the sample container to the solid-phase extraction tube of the Visiprep XSPE vacuum sample processing device.

It is to use solid adsorbents to adsorb target substances in liquid samples, separate the target substances from the matrix and interfering compounds of the sample, and then use elution solution or heating desorption to achieve the purpose of separating and enriching the target substances. Solid phase extraction does not require a large amount of immiscible solvents and does not produce emulsification during the processing; Solid phase extraction can significantly reduce the amount of solvent used due to the use of efficient and highly selective adsorbents (stationary phase); The pretreatment process of solid-phase extraction is simple and cost-effective.

Compared with traditional liquid-liquid extraction, the XSPE sample extraction device of Shanghai solid-phase extraction instrument has the advantages of short operation time, small sample size, no need for extraction solvents, suitable for analyzing volatile and non-volatile substances, and good reproducibility. The XSPE method can be used for the separation, enrichment, and analysis of complex target samples in fields such as environmental chemistry, food, medicine and health, clinical chemistry, biochemistry, and forensic science. The biggest technical advantage of XSPE is its ability to handle samples with very low concentrations.
