Efficiently analyzing lithium cobalt oxide using gas-generating reaction assisted headspace GC.

This study introduces an innovative gas-generating reaction assisted headspace approach for precise quantification of lithium cobalt oxide using headspace GC. The approach utilizes gas chromatographic measurement of carbon dioxide generated through redox reaction between the analyte and oxalic acid in acidified sealed vials. Method validation demonstrated reliable analytical performance, with high precision and acceptable recovery rates in spiked samples. The automated headspace GC technique provides substantial benefits for the rapid quality control of lithium cobalt oxide products. Additionally, this gas-evolution based strategy establishes a framework for indirect determination methods through headspace analysis.
