A primary feature observed in the quartz tube mFPD prototype is its resistance toward hydrocarbon quenching of analyte emis-sion, which is achieved through the presence of the worker flames. Since the SS mFPD does not differ in this aspect of its core design, such quenchingresistant behavior should also be anticipated in its operation. However, since the SS mFPD has also shown decreased background emission and improved signal characteristics here compared to the quartz tube prototype, this property was still necessary and interesting to further investigate. Therefore,in order to better gauge this, experiments were performed under severe quenching conditions with the SS mFPD.
