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.
通过应用一种常压质谱方法——实时直接分析质谱法（DART MS），开发了一种快速鉴定不同种类茶叶中主要成分的方法。还通过特征质谱信号实现了对不同种类茶叶的鉴别。在大气压下，DART MS方法无需任何样品制备，大大缩短了分析时间，实现了原位、快速、准确和高通量分析。
