By applying an ambient mass spectrometric method--direct analysis in real time mass spectrometry (DART MS), a method was developed for rapid identification of the principal constituents in different kinds of tea. The identification of different kinds of tea was also achieved by characteristic mass spectrometric signals. Under atmospheric pressure, DART MS method does not require any sample preparation, greatly reduces the analysis time, realizes the in situ, rapid, accurate, and high-throughput analysis.
