Solid phase extraction column (polymer-based HLB) 60mg/3mL 50 pieces HLB60-3 1 box (50 pieces)

This is a composite polymer solid phase of N-containing vinyl polymer and divinylbenzene. The optimal balance of hydrophobicity and hydrophilicity allows the retention and elution of compounds with a wide range of polarities. A general purpose adsorbent suitable for a wide range of applications. It is composed of resin particles that have both hydrophilic and hydrophobic groups. It can be used to extract samples from complex samples such as blood and urine. It has excellent adsorption rate and reproducibility. The adsorption capacity and loading capacity are 3-10 times that of C18 bonded silica gel. Stable from pH 1 to 14, compatible with most common solvents.
