HLB hydrophilic lipophilic balance filler is prepared by special copolymerization technology and contains a specific proportion of hydrophilic and hydrophobic groups: hydrophobic divinylbenzene structure retains
non-polar compounds, and hydrophilic N-vinyl pyrrolidone structure retains polar compounds. The filler has good water wettability and can adjust the hydrophilic lipophilic balance through the aqueous phase, so as to obtain ideal selectivity. HLB has a good recovery rate for acidic, neutral and alkaline compounds from non-polar to medium polarity. It is especially suitable for the treatment of complex substrates such as blood, urine and food.
- Universal packing, wide application range
- High water wettability, not afraid of solvent drying, not easy to penetrate
- High recovery and good reproducibility
- Adsorption capacity and sample loading are much higher than that of C18 bonded silica gel (3-10 times)
- Withstand pH 1-14 and is compatible with most solvents
