Quantitative analyses of vitamins can be done in minutes with minimal processing, saving time and money with a technique successfully demonstrated by a team of Oak Ridge National Laboratory researchers. Ensuring that food and dietary supplements have the prescribed amount of ascorbic and folic acids is of critical importance because excessive amounts of these vitamins can have a detrimental effect. Using a process called flow-injection tandem mass spectrometry, Gary Van Berkel and colleagues demonstrated results that were in agreement with liquid chromatography-based results obtained by National Institute of Standards and Technology methods. The findings were published recently as a research article in Rapid Communications in Mass Spectrometry.
