Du sökte efter: Kromatografikolonn
Kromatografikolonner separerar molekyler under gas- eller vätskemetoder. Färdigpackade kolonner finns med olika stationärfaser och resiner. De färdigpackade kolonnerna står emot temperatur- och tryckvariationer som uppstår när mobilfasen trycks genom kolonnen. Det finns kromatografikolonner för preparativa och analytiska metoder för att separera komponenter baserad på individuell polaritet, sammansättning och storlek.

Solid phase extraction cartridges, Bond Elut™ CN-E
Supplier: VARIAN
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.

Capillary columns, CP-Al₂O₃/Na₂SO₄
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.

Solid phase extraction cartridges, Bond Elut™ C1
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.

Solid phase extraction cartridges, Bond Elut™ SCX
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.

Solid phase extraction cartridges, Bond Elut™ DEA
Supplier: VARIAN
Bond Elut™ DEA bears some resemblance to Bond Elut™ NH₂ in its properties but with a slightly lower capacity as an anion exchange sorbent. DEA has a moderately non-polar character due to the alkyl side chains on the amino functionality. These groups still afford a medium level of polarity, higher than C₈ but less polar than C₂ or CN-E.
