Bonded Silica SPE Products

Cleanert AQ C18

AQ C18 series using a polar chemical group to modify the spherical C18 surface and enhance the retention for polar substance. The bonded chemical group also make RP surface more hydrophilic, and provide good recovery for both polar and non-polar compounds, especially for water samples.

Cleanert S C18 (End-capped)

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).

Cleanert S C18-N (Non-end-capped)

Cleanert S C18-N is a type of C18 sorbent bonded to silica without end-capping modification, providing extra silanol residuals around the root of alkyl chain on silica surface.

Cleanert PestiCarb (Graphitized Carbon Black)

Cleanert PestiCarb using graphitized carbon material has been used for sample cleanup in pesticide residues in plants or animal tissues.

Cleanert Alumina N (Aluminium Oxide; Neutral)

Cleanert Alumina N sorbent (pH = 7.5) can adsorb molecules by interaction with the aluminum metal center.
Bonna-Agela SPE products

Solid phase extraction (SPE) is one of the most used techniques in sample preparation. It is replacing the conventional time-consuming liquid-liquid extraction (LLE) method. The process of SPE is a miniature version of liquid column chromatography. SPE, utilizing the same type of stationary phases as used in liquid chromatography columns, are practiced in different mechanisms including normal phase, reversed phase, ion-exchange, affinity chromatography and mixed-mode in the fields of agricultural and food, bio-analytical, environmental and forensic applications. Bonna-Agela as a leader of chromatographic media products offers a variety of polymer and silica based SPE products.

Cleanert PAE and DEHP

Food contamination by phthalates has caused considerable hazard to food safety. The most popular used plasticizers are phthalates series, which may cause cancer. Bonna- Aglea provides Cleanert PAE and DEHP to analyze phthalates in different matrices including food containing fats and oil, and aqueous samples.

SPE Method for Determination of Acrylamide in Water

A simple and fast method of solid phase extraction (SPE) disk for the determination of trace acrylamide was developed. Using this new technique along with high performance liquid chromatography (HPLC) and ultraviolet spectroscopy (UV) detection, the feasibility of SPE disk method for rapid enrichment was demonstrated in the determination of trace acrylamide in 500 mL tap water. Active carbon was chosen as the adsorbent to be incorporated into the SPE disk as it gave the best adsorption efficiency.
