Octadecyl modified silica phase for SPE of polar analytes

Base material silica, pore size 60Å, particle size 45µm, specific surface 500m²/g, pH stability 2 to 8, special octadecyl phase for polar analytes, not endcapped, carbon content 15%.

Recommended applications: more polar compounds like pesticides and their polar degradation products, phenols, phenoxycarboxylic acids, nitroaromatics, pharmaceuticals.

Octyl modified silica phase for SPE, not endcapped

Base material silica, pore size 60Å, particle size 45µm, specific surface 500m²/g, pH stability 2 to 8. Octyl phase, not endcapped, carbon content 8%, similar to C₁₈, however slightly more polar. Secondary interactions with polar compounds are more pronounced due to shorter alkyl chains.

Recommended applications: pesticides, PCBs.

Cyanopropyl modified silica phase for SPE

Base material silica, pore size 60Å, particle size 45µm, specific surface 500m²/g, pH stability 2-8, cyanopropyl phase, carbon content 5.5%, polar to mid-polar. In addition to weak hydrophobic interactions selective interactions are possible due to the high electron density of the CN group.

Recommended application: cyclosporins, carbohydrates.

Combination phase for SPE analysis of PAH

Special combination phase, cyanopropyl phase for selective adsorption of polycyclic aromatics via Π-Π interactions, unmodified silica phase for removal of polar compounds.

Recommended applications: Extraction of the 16 PAHs according to EPA from soil samples.

SPE phases for polymer-based RP and ion chromatography

Base material: high-purity polystyrene-divinylbenzene copolymers (PS/DVB)
pore size 100 Å, paricle size 100µm. Verly low degree of swelling, thus very well suited for chromatography. Different modifications for different applications from elimination of nonpolar compounds up to removal of specific polar comonents.

Recommended application:
Removal of interfering compounds

• improves chromatographic separtions, if the interfering components overlap with the analyte in the chromatogram
• improves lifetime of the chromatographic column, since interfering components can irreversibly block the column packing
