Abstract:
Chiral separation is important in biological medicine and other fields. High performance liquid chromatography (HPLC) is widely used in chiral separation and analysis for its economic, rapid and efficient characteristics. Chiral stationary phase (CSP) is the key to achieve chiral resolution in HPLC. Meanwhile, the key to preparing effective CSP is the screening of chiral selector. In recent years, a lot of CSPs with different chiral selectors had been prepared. Silica gel immobilized CSP is especially attached great attention because of its high solvent tolerance and stability. In this paper, the new type of CSPs prepared by using chiral single molecules, polysaccharides, cyclodextrins, macrocyclic antibiotics, crown ethers, calixarenes and alkaloids as chiral selectors are summarized, and the development prospect of immobilized CSPs are also discussed.

Chirality
Chiral objects exhibit a sense of handedness when they interact with another chiral object. For example, our left foot can only fit in the left shoe and not in the right shoe. Achiral objects — objects that have...

Ionic Bonds
When atoms gain or lose electrons to achieve a more stable electron configuration they form ions. Ionic bonds are electrostatic attractions between ions with opposite charges. Ionic compounds are rigid and brittle when solid and may dissociate into their constituent ions in water. Covalent compounds, by contrast, remain intact unless a chemical reaction breaks them.
