Silica-based medium-polarity filler with carboxypropyl groups.
Bond Elut CBA is a silica-based medium-polarity packing material with carboxypropyl groups, which exhibits hydrophilic/hydrophobic interactions depending on the matrix and solvent environment. Its main characteristic lies in weak cation exchange. Due to its pKa value of 4.8, CBA does not require the extremely high alkaline environment that other cation exchange packing materials need for elution. At pH 4.8 and above, most of the functional groups carry a negative charge as cation exchange sites. Lowering the pH to 2.8 neutralizes CBA, allowing it to release and elute the compounds it has retained from the packing material. CBA is particularly suitable when dealing with very strong cationic compounds. Additionally, CBA broadens the selectivity range for counterions compared to other cation exchangers, increasing the options for elution buffers. *For more details, please refer to the PDF document or feel free to contact us.*
Bond Elut Silica is a polar packing material.
Bond Elut Silica is a polar packing material. Non-bonded active silica exhibits acidity. SI is a packing material used for the highly selective separation of compounds with similar structures. To elute target compounds present in a non-polar solvent, you can increase the polarity of the solvent by adding a polar solvent such as THF or ethyl acetate, allowing for recovery. *For more details, please refer to the PDF document or feel free to contact us.
Bond Elut C18 OH is a non-end-capped octadecyl bonded phase, and the silanol groups on the silica surface are activated.
Bond Elut C18 OH is a non-end-capped octadecyl bonded phase, with the silanol groups on the silica surface being activated. The low-load C18 adjusts the activity of the silanol groups under strict QC standards to maintain the best reproducibility for each batch. The activity of the silanol groups enhances the separation and extraction capabilities of metabolites and the retention of basic compounds compared to end-capped C18. Additionally, the 150 Å pore size is suitable for moderately sized molecules that may not be retained by standard 60 Å packing materials. *For more details, please refer to the PDF document or feel free to contact us.*
Alumina is a filler that has extremely high polarity, similar to silica.
Alumina, like silica, is an extremely polar filler. The surface of alumina tends to be stable at a higher pH state compared to non-functionalized silica. Due to its fine particle size and high extraction efficiency, a small amount of filler (50 mg) is generally used. Bond Elut AL-B has the properties of an electron donor and retains compounds with cations and hydrogen bonds. *For more details, please refer to the PDF document or feel free to contact us.*

Bond Elut C18 is a highly hydrophobic silica-based packing material within the product line.
Bond Elut C18 is a highly hydrophobic silica-based packing material within the product line. It has extremely high retention characteristics for nonpolar compounds and is a popular packing material. C18 is a silica-based packing material that retains most organic compounds from an aqueous matrix, but it may be avoided due to its lack of selectivity. However, when the structures of the target compounds vary significantly and have a wide range of polarities, there is an advantage in retaining them all at once. The polarity interactions between the target compounds and the packing material are not significant due to the strong effect of long-chain hydrocarbons. When analyzing low molecular weight compounds, C18 does not retain salts and allows them to pass through, making it useful for desalting the aqueous matrix prior to ion exchange. *For more details, please refer to the PDF document or feel free to contact us.*
