Bond Elut™ Plexa PCX uses a polymeric cation exchange resin that combines the outstanding properties of Bond Elut™ Plexa - superior flow characteristics and improved analytical performance - with strong cation exchange functionalities. This mixed-mode SPE sorbent removes neutral and acidic interferences from the matrix, concentrates basic analytes and therefore improves sensitivity in the determination of basic compounds.

Supplier: VARIAN

Bond Elut™ SCX is a strong cation exchanger with a very low pKa. Although the pKa is similar to Bond Elut™ PRS, the presence of the benzene ring in the functional group increases the potential for non-polar interactions. This non-polar characteristic becomes particularly important when conducting ion-exchange from aqueous systems, where selectivity towards compounds exhibiting cationic and non-polar character is seen.

A medium polarity sorbent with many uses, Bond Elut™ CN-E is ideal for applications in which extremely non-polar compounds would be irreversibly retained on high carbon load sorbents such as C₈ and C₁₈. This endcapped version of the cyano sorbent is best utilised when extracting analytes from an aqueous matrix.

Supplier: VARIAN

CP-Al₂O₃/Na₂SO₄ is an aluminum oxide PLOT column that offers high selectivity for separating ppm levels of C₁ to C₅ hydrocarbons in a main stream of C₁ to C₅ hydrocarbons. The Na₂SO₄ deactivation salt provides a polar Al₂O₃ surface, so that unsaturated compounds such as ethylene and acetylene are retained longer. These columns analyse more compounds in a single run than packed columns, while still delivering higher resolution and faster analysis times. When compared to liquid stationary phases, CP-Al₂O₃ provides increased selectivity and allows all C₁ to C₅ hydrocarbon isomers to be separated. CP-Al₂O₃ operates without the need for sub-ambient cooling.

Supplier: VARIAN

Due to the methyl group and subsequent low carbon load, Bond Elut™ C1 is the least retentive of all alkyl group bonded phases for non-polar compounds. However, due to the extensive end capping of this sorbent to mask polar silanol activity, retention and elution of polar and multi-functional analytes can still be achieved. Typical applications include plasma, urine and aqueous samples.
