Polymeric SPE Cartridge
1. Polymeric MCX SPE Cartridge
Polymeric cation exchange reversed-phase adsorbent. It has high selectivity to basic compounds.
Features:
The polymeric cation exchange solid phase extraction cartridge has high selectivity and sensitivity to weakly basic compounds. The matrix is polystyrene-divinylbenzene polymer.
MCX is designed to overcome the traditional silica matrix polymeric solid phase Limitations of extraction adsorbents.
Polymeric MCX SPE Cartridge provides dual retention modes: ion exchange and reverse phase, and the retention occur in a clean, stable, high surface area, stable organic copolymer in the range of pH 0-14 superior. Used for the detection of melamine in milk, food, and feed.
2. Polymeric MAX SPE Cartridge
Polymeric anion exchange reversed-phase adsorbents have high selectivity and sensitivity to acidic compounds.
Features:
Polymeric-type anion cartridge, strong anion exchange/reverse phase mixing bonded to the polymer matrix, has good adsorption to weakly acidic substances because it is a polymer matrix.
Polymeric MAX SPE Cartridge is designed to overcome the traditional silica-based polymeric solid phase and the limitation of extraction adsorbent, MAX is a kind of stable polymeric anion exchange in the range of pH0-14, wettable polymer adsorption.
3. Polymeric HLB SPE Cartridge
HLB adsorbent is a macroporous copolymer composed of lipophilic divinylbenzene and hydrophilic N-vinylpyrrolidone in a certain proportion.
The retention mechanism is the reverse phase, through a “special polar capture group” to increase the retention of polar substances to provide good water wettability.
Features:
Polymeric HLB SPE Cartridge is a universal adsorbent for acidic, neutral, and basic compounds:
- High and stable recovery rate. Even if the column bed dries up, the recovery rate will not be affected.
- High adsorption capacity. Compared with silica gel, the surface area of the adsorbent is 2-3 times larger, and the capacity factor is greatly improved. The adsorption capacity of 30mg HLB is equivalent to 100mg C18.
- Outstanding batch-to-batch reproducibility.
- Good chemical stability.
- Compatible with various automated solid phase extraction devices.
