Technical Specificatio

Silica Unbounded Silica Gel
Extracting polar compounds Silica is an unbounded silica gel sorbent. It has the strongest polarity among all normal phase sorbents, able to retain polar compounds in samples, particularly compounds with a similar structure. - Very strong retention for polar compounds - High sample loadabilities -Capable of separating compounds with a similar structure			Specifications 1.Surface area: 480 m2 /g 2.Particle size: 40 - 75 µm 3.Pore size: 70 Å Applications - Analysis of drugs, poisons, pollutants and their metabolites in biological matrices - Separation of biomolecules such lipids, antibiotics, bile acids and saccharides - Determination of mycotoxins such as fumonisins in foods -Determination of preservatives in cosmetics and skin care products

Florisil Pesticide Grade Florisil
Extracting multiresidual pesticides Florisil is a selective adsorbent comprised of synthetic magnesium-silica . It’s strongly polar, extremely active, highly porous and able to retain low to moderately polar compounds such as chlorine-, nitrogen- and phosphorus-containing pesticides. In analysis of multiresidual pesticides, Florisil has proven to be an effective, low- cost choice, and adopted in the U.S. EPA method 608 and China NY/T method 761. - Good retention for most pesticides - Suitable for viscous samples Specifications 1.Particle size: 150-250 µm			Applications -Determination of chlorine-, nitrogen - andphosphorus -containing pesticides in foods. - Determination of mycotoxins in foods. Related Methods - EPA 608 Organochlorine Pesticides and PCBs by GC/HSD - NY/T 761 Pesticide multiresidue sceen methods for determination of organophosphorus pesticides, organochlorine pesticides, pyrethroid pesticides and carbamate pesticedes in vegetables and fruits - GB 5009.265-2016 Determination for PAHs in foods

Al-A /AL-B /AL-N Alumina
Extracting aromatic amines Extremely polar sorbent, similar to silica.More stable under high pH conditions than unbonded silica. The surface retentive electrons induce electron-rich compounds like aromatic species and aliphatic amines, and compounds with electronegative group like oxygen, phosphorus and sulfur atoms. Giving rise to strongly polar retention and Lewis acidity.Alumina is available in acidic (ALA), neutral (ALN) and basic (ALB) formulations from which you can choose an appropriate one according to your specific applications. - Good retention for electron-rich compounds suchas aromatic amines - More stable than un-bonded silica in high pH conditions - High capabilities Specifications 1.urface area: >150m2/g 2.pH: 4.0 for ALA, 7.0 for ALN, 9.5 for ALB			Applications - Analysis of amines, phenols and glycosides in biological matrices, such as pyrocatechol - Determination of residual pesticides, veterinary drugs and pollutants in vegetables and fruits, such as Sudan dyes, malachite green and organophosphorus pesticides - Determination of synthetic pigments in water - Analysis of oil components Related Methods -GB/T 23816-2009 Method for determination of triazine herbicide residues in soybean -GB/T 19681-2005 The method for the determination of Sudan dyes in foods-High performance liquid chromato graphy -GB/T 20361-2006 Determination of malachite green and gentian violet residues in fishery products -High performance liquid chromatography with fluorescence detector -NY/T 1756-2012 Determination of malachite green in feeds

GCB Graphitized Carbon Black
Extracting herbicides in drinking water Carb- GCB is composed of sheet-like,nonporous graphitized carbon black with aromatic six- member ring structure and positive charges. It has reversed phase and ion exchange retention mechanisms, retaining non-polar compounds,such as organochlorine pesticides,as well as polar compounds, such as surfactants. Owing to its sheet-like, nonporous structure, Carb-GCB enables higher extraction speeds and capabilities than silica-based sorbents. - Higher extraction speed and capability - Suitable for large volume samples Specifications 1.Surface area: 100 m2/g 2.Particle size: 100-300 mesh			Applications - Removal of pigments in vegetables and fruits. - Determination of organochlorine pesticides, ethyl carbamate, alkaloids and mycotoxins in water, beverages, vegetables and seafood Related Methods - EPA Method 523: Determination of Triazine Pesticides and their Degradates in DrinkingWater by Gas Chromatography/Mass Spectrometry (GC/MS) -EPA Method 535: Measurement of Chloracetanilide and Other Acetamide Herbicide Degradates in Drinking Water by Solid Phase Extraction and Liquid Chromatography/Tandem Mass Spectrometry (LC/MS/MS)
