Application Note: Quantitative Analysis of Citric Acid
30 July 2019
Citric acid is an important organic acid used extensively in food and pharmaceutical industries. It is produced mainly by submerged fermentation and the progress of the reaction can be followed by pH titration. However, wet-chemical conventional laboratory reference methods for titration are tedious and time consuming. In this application note, ABB Analytical Measurements demonstrates the use of FT-NIR spectroscopy as a quicker, cheaper and simpler alternative for reaction monitoring.
