Reverse Phase
With reverse phase plates, Whatman provides 60Å K6 with a choice of two carbon chain lengths plus Multi-K Dual Phase plates. The chain length of the hydrocarbon functional groups primarily affects retention and the ability to accommodate the water content of solvent systems. The shorter C-2 carbon chain is used for increased polarity and affinity for aqueous solutions while the longer C-18 chains give greater retention and hydrophobicity. KC-18 plates are also available with a preadsorbent zone which facilitates sample application, especially with dilute samples in less volatile solvents.
Features and benefits
- Proven performance, quality, and reliability
- Compatibility with highly aqueous solvent systems, for greater flexibility
- Ready correlation with reverse phase HPLC results
Multi-K Dual Phase for Demanding Samples
Multi-K combines a 3 x 20 cm C-18 reverse phase stationary phase with a 17 x 20 cm normal phase silica stationary phase on one TLC plate. It allows two-dimensional separations of mixed polarity samples on one plate. Components are first separated by reverse phase TLC, then the plate is dried, turned 90°, and developed with a normal phase solvent mix.
Features and benefits
- Cleanup and analysis of complex samples
- Two dimensional TLC on one plate
