HILIC Separation of Carboxylic Acids

Hydrophilic acids are separated on Obelisc N mixed-mode HILIC column. Seven carboxylic acids are separated based on their polarity and pKa values. Changes in ionization states of acids and stationary phase can be used to control elution order of organic and inorganic acids.

Application Analytes:
Fumaric Acid
Hydroxybenzoic Acid
Malic Acid
Mandelic Acid
Methylmalonic Acid
Organic Acids
Succinic Acid
Tartaric Acid
