VF-200ms is designed with a unique selectivity for compounds rich in dipole-dipole interactions, resulting from the electrophilic nature of the trifluoropropyl stationary phase.

Supplier: VARIAN

VF-23ms features a unique combination of high polarity and low bleed to enable more accurate analysis of very polar analytes.

Supplier: VARIAN

The CP-Select 624 CB is a highly reproducible version of the popular 624 phase and has 2-3 times lower bleed than conventional columns.

Supplier: VARIAN

Bond Elut™ C8 is very similar in properties to C18, but is not as retentive for non-polar compounds, due to its shorter hydrocarbon chain, and therefore reduced carbon loading. C8 is an excellent replacement for C18 when analytes are too strongly retained for effective elution. The potential for polar interactions is somewhat higher than for C18 because there is less coverage of the silica surface. These polar interactions are not, however, a significant property of C8.

Supplier: VARIAN

Bond Elut™ C2 is a fairly non-polar sorbent because of the short chain length of the functional group. C2 is often used during the process of method development if analytes are retained too strongly on a C8 or C18 phase. The polarity of C2 is slightly lower than a cyano phase for polar interactions.

Supplier: VARIAN

Bond Elut™ plexa PAX non-polar/anion-exchange polymeric SPE offers excellent clean-up and reproducibility, and is suitable for polar and non-polar acidic analytes.

Supplier: VARIAN

CBA is a mid-polarity sorbent and weak cation exchanger (pKa 4,8). It can be used with a wider range of counter-ions than lower pKa sorbents like SCX and will demonstrate easier elution of quaternary amine functionalised analytes.

Supplier: PerkinElmer

Small pore silica-based sorbent used for separation of small molecules. Non-functional and polyfunctional C8 and C18 are available.

Supplier: VARIAN

CP-PoraPLOT Amines is a unique column specially designed for the high retention analysis of very volatile amines.
