title: Gas chromatographic determination of indoles in human mouth and saliva using a flameless alkali sensitized detector (nitrogen/phosphorous-specific detector, NPD).
abstract: A simple and sensitive NPD determination of the indoles in the mouth and saliva of a nonsmoker and a smoker was investigated. The present method using NPD detection was found to be suitable for the analysis of the odors in human mouth based on the indoles.
