NexeraOrganic Acid Analysis System and its Application

User Benefits

- Excellent selectivity and high sensitivity are obtained in analysis of organic acids. - Stable analyses can be conducted easily by using the Mobile Phase Reagents Kit for Organic Acid Analysis, which eliminates the time and trouble of reagents formulation. - The Nexera Organic Acid Analysis System can also be applied to analyses of short-chain fatty acids and lower fatty acids in various fields.

Introduction

Organic acids are highly hydrophilic compounds which are difficult to retain in the ODS columns generally used in HPLC. Regarding detection, organic acids have absorption in the short wavelength region in Ultra Violet absorbance detection, and are easily affected by interferences from contaminants, so ingenuity is required in the detection method in order to perform analyses with high sensitivity and high selectivity. The Nexera organic acid analysis system employs the “post- column pH buffering electric conductivity detection method" in which organic acids are separated using ion exclusion chromatography and then mixed with a pH buffering reagent to enhance detection sensitivity. It is optimized for organic acid analysis. Moreover, results with excellent repeatability can be obtained easily by using a Shimadzu mobile phase and reagent kit for organic acid analysis, which includes the mobile phase and the pH buffering reagent. This article introduces applications and retention indexes obtained by the Nexera Organic Acid Analysis system.
