Cocaine detection in liquid using a fibred platform and mid-infrared quantum cascade laser

A miniaturized, trace level sensor for cocaine is presented. A quantum cascade laser emitting at 1720 cm-1 is coupled to a fibred absorption flow-cell. A detection limit lower than 250 ng/mL (84 ppb) is reported.
