Abstract:
1. A vapor sampling adapter for use with a direct analysis in real time mass spectrometer, said mass spectrometer having an ion source and a sample port, comprising: a vapor transport line having an inlet end and an outlet end for transporting sample vapor; and a manifold having a first manifold port for connecting said manifold to said outlet end of said vapor transport line, a second manifold port for connecting said manifold to said mass spectrometer ion source, and a third manifold port comprising an insertion tube inserted in the mass spectrometer sample port for connecting said manifold to said mass spectrometer sample port; wherein said sample vapor flows from the inlet end of said vapor transport line through the vapor transport line to said manifold where it mixes with gas entering from said ion source before entering into said sample port where it is analyzed by said mass spectrometer.
