CHROMABOND® C8
Octyl modified silica phase for SPE, not endcappedBase 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.

CHROMABOND® SB
Quaternary ammonium modified silica anion exchanger for SPE (SAX)Base material silica, pore size 60 Å, particle size 45 µm, specific surface 500 m²/g, pH stability 2 to 8. Silica modified with quaternary amine. Strongly basic anion exchanger (capacity ~ 0.3 meq/g). Not suited for very strong anions such as sulphonic acids, because these are difficult to elute.Recommended application: organic acids, caffeine, saccharin.

CHROMABOND® PS-OH- / PS-H+
The innovative cation exchanger offers:mixed-mode SPE phase with distinct cation exchange and RP properties excellent enrichment of basic analytesmodern support polymer with optimised pore structure and large specific surfacegood reproducibility, reliable and cost-efficient analysesmore aggressive washing procedures for matrix removal possiblecleaner samples and protection of analytical HPLC and GC instrumentationquantificationof analytes from heavily contaminated sampleslower limits of detection also for critical matrices... the perfect fit for basic analytes in comination with CHROMABOND® HR-XSPE phases for polymer-based RP and ion chromatographyBase 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 chromatogramimproves lifetime of the chromatographic column, since interfering components can irreversibly block the column packing
