Ambient mass spectrometry as a tool to determine poultry production system history: A comparison of rapid evaporative ionisation mass spectrometry (REIMS) and direct analysis in real time (DART) ambient mass spectrometry platforms

Ambient mass spectrometry is a tool of growing interest for the testing of foodstuffs over the fifteen years since the pioneering techniques of desorption electro-spray ionisation (DESI), direct analysis in real time (DART) and atmospheric pressure solid analysis probe (ASAP) were first demonstrated. In this study, rapid evaporative ionisation mass spectrometry (REIMS) was compared with DART to assess whether either system was capable of correctly identifying poultry raised in one of six distinct production systems.
