Hundreds of volatile/semi-volatile aroma and flavor compounds have been identified in coffee using traditional laboratory based headspace GC/MS systems. 1. We present a study for rapid fingerprinting of coffee volatile/semi-volatile compounds using solid phase micro-extraction (SPME) coupled to a portable GC/MS system for separation and detection.

Volatile organic compounds (VOCs) are a series of compounds with high . vapor pressure and boiling points from 50 to 250 degrees centigrade. These characteristics lead to the tendency for large numbers of molecules to evaporate, or volatilize, from their solid state into the air. VOCs are present in the environment from a
