The analysis of organic acids is important for both the food and cosmetic industries. Organic acids are naturally found in a wide variety of food products, fruits, and corresponding beverages. They are also used in the cosmetic industry as dermatological agents. Agilent ZORBAX StableBond columns are highly stable at low pH, including the use of mobile phases containing 0.1% trifluoroacetic acid at pH 2.1. ZORBAX StableBond columns provide good peak shapes for acidic compounds.
This document details the analysis of organic acids, which are naturally found in various food products and used in the cosmetic industry. It highlights the importance of this analysis for the food and cosmetic sectors.
