Abstract
A flavor monitoring system comprises a photo-ionization detector based sensor for measuring the amount of flavor in flavored cigarette filters The sensor has an intake port and an exit port open to the atmosphere. An enclosure with a removable cover is connected to the intake port of the sensor, and the enclosure is constructed and arranged to receive a flavored cigarette filter to be analyzed. The photo-ionization detector based sensor draws a gaseous sample from the flavored filter within the enclosure, ionizes the flavor sample and displays a reading representative of the amount of flavor in the filter. Subsequently the reading may be converted to a flavor amount in milligrams by multiplying the reading by a correlation factor.
