silica based

AccuBONDSilicone basedSPEThe product is based on non bonded active irregular silica gel (silica gel based) particles. Its main interaction is polar interaction (such as hydrogen bonding). Due to the ionizability of silanol groups, they can be used in moderate concentrationspHUsed as a weak cation exchanger within the range of values.

Cyano group（CN）

AccuBONDCyano group（CN）SPEThe product is based on irregular silicone (silicone based) particles. This polar and bonded adsorbent can exhibit polar and non-polar interactions. It can be used as a non-polar adsorbent to extract polar and non-polar molecules from water-soluble samples, as well as polar molecules from relatively non-polar solvents.

Diol（OH）

AccuBONDGlycolSPEThe product is based on irregular silicone (silicone based) particles. Depending on the preparation of the small column and the sample matrix, this polar bonded adsorbent can exhibit polar and weakly non-polar interactions. After appropriate treatment of the small column, this adsorbent can be used as a non-polar adsorbent to extract relatively non-polar molecules from water-soluble samples, but it is more commonly used to extract polar molecules from relatively non-polar solvents through hydrogen bonding interactions.

Amino group（NH2）

AccuBONDAmino group（NH2）SPEThe product is based on irregular silicone (silicone based) particles. This adsorbent has a dual function and can be used as a polar stationary phase or as an anion exchanger. When using non-polar solvents (such as hexane) for pretreatment, it can interact with-OH、-NHperhaps-SHThe molecules of functional groups form hydrogen bonds. existpHValue less than or equal to7.8In an aqueous solution environment, it can be used as a weak anion exchanger.
