title: Aldehyde condensation products as derivatives for the vapor phase analysis of biogenic amines.
abstract: The mass spectra of six tetrahydroisoquinolines and five tryptolines are surveyed. It is concluded that tryptolines are suitable for analysis of tryptamines, after condensation with aldehydes.
