Solid Phase Extraction Column Specifications

Common solid phase extraction columns are mostly polyethylene-based injection syringes. The device is equipped with two pieces of polypropylene or glass fiber. The two pieces are filled with a certain amount of chromatographic adsorbent. filler). The upper end of the solid phase extraction column is open, and the lower end is a liquid outlet, and the liquid is discharged from the outlet after passing through the adsorbent. According to the volume above the solid phase extraction column packing, the specifications of the solid phase extraction column can be divided into 1 mL, 3 mL, 6 mL, 10 mL, 15 mL, 20 mL, 30 mL, 60 mL, and so on. There are also special-sized solid phase extraction columns that are produced according to specific application requirements. From the outside of the solid phase extraction column, the classic solid phase extraction column is similar to the injection syringe and is straight. Another type of solid phase extraction cartridge is funnel-shaped at the top, making it easier to load more samples at once in manual operation.
The non-sieve SPE column is an integrated new SPE column. The product uses the exclusive technology of mystery technology to specially process the bonded silica fillers such as C18 and C8 to make it have high mechanical strength and toughness. It is not necessary to add polyethylene porous baffle as support in the column. The mystery proprietary technology product “Integrated SPE Solid Phase Extraction Column [1]” is the first integrated SPE column on the domestic and international markets.
Product advantages:
1, no sieve plate, perfect to avoid the “non-specific adsorption” caused by the sieve plate.
2, the filler is stable and can be good, there will be no problems such as loose packing.
3. The integrated design of the whole packing effectively avoids the “ditch effect”.
4. It can choose packing with particle size as low as 8-10μ, which greatly improves the separation efficiency and sample loading.
