CỘT SPE HLB

HLB SPE Cartridge Extraction of non-polar to moderately polar acidic, neutral and basic compounds HLB hydrophilic lipophilic balance filler is prepared by special copolymerization technology, containing a specific proportion of hydrophilic and hydrophobic groups: hydrophobic divinylbenzene structure retains non-polar compounds, hydrophilic N-vinyl The pyrrolidone structure retains polar compounds. The filler has good water wettability, and the hydrophilic-lipophilic balance can be adjusted by the water phase, so as to obtain the desired selectivity. HLB has a good recovery rate for non-polar to medium-polar acidic, neutral, and basic compounds, and is especially suitable for the treatment of complex matrices such as blood, urine, and food. Features: General purpose packing with wide application range. High water wettability, not afraid of solvent drying and difficult to penetrate. High recovery rate and good reproducibility.Adsorption capacity and sample load are much higher than C18 bonded silica (3-10 times). Resistant to pH 1-14 and compatible with most solvents. Parameter: Specific surface area: 600 m2 / g Average particle size: 40 um Average pore diameter: 300A Aapplication: Detect illegal drugs (antidepressants, h eroin) and drug residues in the blood. Detection of antibiotics (penicillin, nitrofuran, chloramphenicol, etc.), catecholamines and microcystins in food. Detection of veterinary drugs (tetracyclines, quinolones), pesticides and mycotoxins in dairy products.
