Dye, Hydrophilic, Ionizable
Analyzing Compounds Methyl Red, Methyl Orange, Methylene Blue, Nile Blue A

 

Application Column

SHARC 1

The SHARC™ family of innovative columns represents the first commercially available columns primarily utilizing separation based on hydrogen bonding. SHARC stands for Specific Hydrogen-bond Adsorption Resolution Column. Hydrogen bonding involves an interaction or attraction between a bound hydrogen atom and molecules containing electronegative atoms, such as oxygen, nitrogen, and fluorine.
