Abstract
Commercial aqueous solution of glutaraldehyde which consists of products arose from glutaraldehyde have been analysed by capillary gas chromatography (GC) and capillary gas chromatography-mass spectrometry (GC-MS). The gas chromatographic seperations of aqueous solutions were carried out well on SE-54 coated fused silica capillary column. The capillary GC-MS analyses were performed by electron impact (EI) , field ionization (FI) and chemical ionization (CI) mode using ammonia, isobutane, ammonia-pyridine and isobutane-pyridine as the reactant gases. The ammonia CI mass spectra provided the best information for the identification of products in the aqueous solution. The several products formed by aldol condensation and hydration-polymerization were identified.
