✦ Synopsis

SUMtiARV

A gas chromatograph and high-resolution mass spectrometer, coupled via a membrane separator, are used for the analysis of samples for traces of nitrosamines: The nitrosamines are detected by parent ion monitoring with a detection limit of I mg/l on injected material. The gas chromatograph incorporates a pressure-programming and peak-cutting device which is described in cletail. Overall analysis time is substantially shorter than for isothermal or temperature-programmed runs.
