Fig 2A displays the analyte response obtained in the normal arrangement using a counter-current analytical flame on a SS capillary inserted through the top of the device. As seen, a modest analyte peak eluting near 1.5 minis produced. By comparison, Fig 2B demonstrates the same experiment when the analytical flame is operated at the junction of the new orthogonal and central SS mFPD channels (i.e. with out a capillary)
