Study on Discharge Behavior of Pencil Lead at Ambient Pressure by Mass Spectrometry

Graphite and clay mixed in pencil lead, with non-standard proportions will be read correctly by computer card reading equipment and identified by non-specialists. In this paper, a rapid and effective method based on atmospheric mass spectrometry utilizes quality evaluation for the pencil lead by the...
