HLB Hydrophilic-Lipophilic Balanced

The HLB (Hydrophilic-Lipophilic Balance) SPE Cartridges are produced using a sorbent with special copolymerization technique, containing a specific ratio of hydrophilic and hydrophobic groups. The hydrophobic divinylbenzene structure retains non-polar compounds, while the hydrophilic N-vinylpyrrolidone structure retains polar compounds. This sorbent has excellent water wettability and can adjust the hydrophilic-lipophilic balance through the aqueous phase to achieve ideal selectivity. HLB SPE Cartridges have good recovery rates for acidic, neutral, and basic compounds from non-polar to moderately polar substances, making it particularly suitable for processing complex matrices such as blood, urine, and food.

Details

Features:

Universal sorbent with wide application range.
High water wettability, resistant to solvent drying, and not easily penetrated.
High recovery rates and good reproducibility.
Adsorption capacity and sample load are far higher than C18 bonded silica gel (3-10 times).
Can withstand pH 1-14 and most solvents.

Application:

Detection of drugs and illegal substances in blood (antidepressants, heroin).
Detection of antibiotics (penicillins, nitrofurans, nitrogen mustards), catecholamines, and microcystins residues in animal-derived foods.
Detection of drug residues (tetracyclines, quinolones), pesticides, and mycotoxins in dairy products.
