Solid-phase extraction cartridges on PS/DVB sorbent for cleaning samples before analysis
Copure HLB series - double hydrophilic-lipophilic phase for a wide range of analytes
Copure HLB cartridges for solid-phase extraction on the PS/DVB copolymer sorbent - for cleaning and concentrating samples before chromatographic analysis.
The sorbent combines hydrophobic divinylbenzene and hydrophilic N-vinylpyrrolidone fragments, which ensures the retention of both polar and nonpolar compounds in one cartridge. Cartridges are produced as polypropylene tubes of different volumes with different sorbent weights, which allows you to choose the format for the sample volume. water wetability and resistant to drying, which makes it easier to condition the column before applying the sample.
The sorbent is a polystyrene/divinylbenzene copolymer with a particle size of 20–60 μm and a specific surface area of 500–750 m2/g, the coefficient of variation between cartridges is less than 5%. Stable in the pH range 0–14. The line includes formats: 30 mg/1 ml (100 pcs/up.), 60 mg/3 ml (50 pc/up.), 150–200 mg/6 ml (30 pc/up.), 500 mg/6 mL (30 per pack), and 500 mg/12 mL (20 per pack). The cartridge body is polypropylene.
