HPLC Method for Citric Acid on Newcrom B by SIELC Technologies
High Performance Liquid Chromatography (HPLC) Method for Analysis of Citric Acid
Citric Acid is a naturally occurring organic acid found in citrus fruits; it is also an intermediate in the citric acid cycle of aerobic organisms. It is used industrially as an acidity regulator, flavoring, detergent, and more than 2 million tons are produced annually. It’s chemical formula is C₆H₈O₇.
Citric Acid can be retained and analyzed using the Newcrom B stationary phase column. The analysis utilizes an isocratic method with a simple mobile phase consisting of water and acetonitrile (MeCN) with a formic acid buffer. Detection is performed using CAD.
