The GERSTEL PFC allows for the collection of individual compounds, a series of compounds, or specific classes of compounds. Thanks to microprocessor control, trap switching times can be selected to within 0.01 minutes. This permits reliable collection of individual compounds that are closely resolved.

The GERSTEL ODP allows the sensing of compounds by the human nose as they elute from the gas chromatograph. The effluent is split as it leaves the column so that it arrives simultaneously at the nose and at the detector. This way additional information is gained on compounds that are responsible for specific odors.
