AQ C18 series using a polar chemical group to modify the spherical C18 surface and enhance the retention for polar substance.
Cleanert PEP-2 is made of polydivinylbenzene on which the surface is functionalized with vinyl pyrrolidone and urea.
Bonna-Agela's Durashell series columns could be used under a wide pH range from 1.5 to 12.0. Durashell series columns have a hybrid technology stationary phase surface, followed by molecular modifications. The patented hybrid technology provides a strong hydrophobic protective layer on the silica surface, allowing the columns to be used at extremely high and low pH. It also reduces excessive hydro
The Venusil AQ C18 column is designed for the separation of polar, medium-polar and non-polar compounds from low to medium pH. This column is more polar than XBP C18, but less polar than ASB C18. With a special surface treatment, Venusil AQ C18 is made to be compatible with 100% aqueous mobile phases.
Bonna-Agela's unique sol-gel process technology generates an uniform surface that produces an universal column applicable to several kinds of HPLC applications.
The system includes a borosilicate glass funnel, a sintered borosilicate glass membrane core on the neck, aluminum clamp, and borosilicate glass fi lter fl ask.
Bonna-Aglea provides Cleanert PAE and DEHP to analyze phthalates in different matrices including food containing fats and oil, and aqueous samples.
Cleanert PCX is a mixed-mode, strong cation exchange sorbent which provides dual retention modes of reversed-phase and cation-exchange.
Cleanert PEP is made of polydivinylbenzene on which the surface is functionalized with vinyl pyrrolidone. The material has a balanced hydrophilic and hydrophobic property and can be used in the entire pH range of 1-14.
Cleanert Silica use unbonded, activated irregular silica as sorbent. This sorbent exhibits high polar interactions and is used to retain polar interference and to pass through weak-polar or non-polar compounds of interest such as oil samples. In addition, the silanol groups are ionizable at intermediate pH, so it can be used as a weak cation exchanger.
Cleanert S C18 columns and plates are packed with octadecylsilane bonded silica sorbents. The sorbent is double end-capped and has a high bonding density (%C > 17). These products can be used for desalting biomolecules, such as proteins and DNAs.
The Venusil ASB series columns are specially designed for the separation of polar compounds under low (extremely stable at pH=0.8) to medium pH condition. The stationary phase is bonded with unique bulky silanes that sterically protect the siloxane bond. We offer a line of bonding chemistry of C1, C8, C18 or Phenyl groups presenting a broad selection of different polarity for various applications.
