A miniaturized simplified gas-chromatographic system for fast, easy and reliable fish freshness and quality analyses is proposed. Microsystem technologies are used for the miniaturization of the two main components of the system, namely the packed GC separation column and the Metal Oxide solid state detector. The proposed system is highly application-specific, integrating all the components necessary for automatic analyses of fish samples to determine the freshness by quantifying volatile amines. The system prototype is described in detail and preliminary in-field validation results are reported.
