ClaricepTMFlash positive phase silicone has SiO4Tetrahedral structure, active hydrophilic surface. Water molecules form acidic silica gel through hydrogen bonding with exposed surfaces. The porous properties and silanol functional groups make silica gel an economical chromatographic separation material that can separate weakly polar compounds, which requires the use of a less polar mobile phase.

ClaricepTMFlash amino column
ClaricepTMFlash amino columns are supported on silica gel and bonded with propylamine functional groups. These fillers belong to polar stationary phases and weak anion exchangers, with dual functions and unique retention properties. In organic solvent systems, it can be combined with - OH- NH, Or - SH functional groups form hydrogen bonds in the analyte. It can also be used as a weak anion exchanger under acidic conditions to remove sulfonic acid ions and strong anion interferences from the sample.
ClaricepTMFlash HILIC Column
Bona Aijer's amide column is compatible with both normal and reverse phase mobile phase systems, such as methanol, acetonitrile, and water, making it more convenient for solvent treatment than ordinary silica gel columns. At the same time, HILIC material and C18 material have opposite retention characteristics in the reverse phase system, with weaker retention than NH2 in the normal phase system, allowing for the elution or retention of substances that are difficult to elute under normal phase conditions or weakly retained under reverse phase conditions. ClaricepTMThe Flash HILIC column has good reproducibility, especially in the aqueous phase with excellent lifespan, which compensates for the traditional NH2 The shortcomings of the pillar.
Suitable for samples that are insoluble in non-polar solvents such as n-hexane, isopropanol, toluene, and dichloromethane
Suitable for retaining strong polar substances in silicone columns.

ClaricepTMFlash Reverse Column
Reverse phase packing bonds non-polar alkyl functional groups such as C4, C8, C18, etc. This reverse phase separation mode is opposite to the normal phase. In reverse phase chromatography, non-polar or hydrophobic compounds are strongly retained, while polar samples are weakly retained, allowing for faster passage through the column bed. Due to its good reproducibility and wide range of applications, the use of reverse phase packing is becoming a popular purification and separation technology.
