title: Determination of carbon monoxide in tuna by gas chromatography with micro-thermal conductivity detector.
abstract: The suitability of a portable gas chromatograph equipped with a micro-thermal conductivity detector for the head-space determination of carbon monoxide (CO) in tuna samples is evaluated; CO is estimated after its liberation from tissue by acidic treatment at 70 degrees C. Using the tested technique, the CO contents in untreated and suspected treated samples are analyzed. A limit of detection of approximately 13 ng/g is reached. The results demonstrate that this apparatus has performances similar to more expensive and sophisticated instruments.
