Restek Chiral GC Capillary Column, Rt-bDEXcst 30 m, 0.25 mm ID, 0.25 µm

By adding β or γ cyclodextrin to our bonded Rtx-1701 stationary phase, we greatly enhance overall utility and column lifetime for our chiral columns, compared to columns that have pure cyclodextrin stationary phases. Separations of more than one hundred chiral compounds have been achieved using our unique DEX columns, and our columns continue to demonstrate stability after hundreds of temperature program cycles.

What are chiral compounds? Any carbon atom that is bonded to four different groups is a chiral or an assymetric carbon. Molecules containing one or more of these carbon centers are considered chiral molecules. Chiral centers can exist in two forms called enantiomers. These two forms are non-superimposable mirror images of each other. They have similar physical properties but dissimilar chemical and biochemical properties.
