Cost-effective flow injection analysis systems for acetic acid

Abstract

We propose cost-effective flow injection analysis systems for acetic acid. The flow systems can be assembled with different types of components, including a clinical saline bag and laboratory-made detectors, resulting in various degrees of automation, varying from very simple ones to fully computerized control. The flow injection titrations are based on neutralization and are monitored by either spectrophotometry or conductometry. The flow injection procedures can be performed under conditions at non-steady or steady states. The proposed procedures are demonstrated for the application of analysis of vinegar samples for acidity. © 2000 John Wiley & Sons, Inc. Lab Robotics and Automation 12:129–132, 2000
