Amines are chemicals of industrial significance, both as raw materials as well as final products produced.The analysis of amines without derivation by gas chromatography is one of the most difficult applications to be conducted.The high polarity and basic nature of the amine compounds often resulted in the loss of analytes throughout the entire gas chromatographic flow path, from inlet liner to detector.One of the known areas with a significant loss is in the capillary column due to the acidic nature of fused silica substrate as well as common stationary phases like polydimethylsiloxane.
