Patent ID: 8913239

Claim:
A quenching resistant multiple flame photometric detector (mFPD), comprising (a) a conduit comprising a proximal and a distal end, and also comprising: (1) an analyte inlet positioned at the proximal end of the conduit providing for a flow of analyte towards a worker flame region; (2) a hydrogen inlet positioned at the proximal end of the conduit; (3) a worker flame region comprising at least a first and second work flame in fluid connection with at least a first and a second oxygen inlet positioned between the proximal and distal ends of the conduit providing for flow of oxygen towards said first and second worker flames; (4) a final oxygen inlet at the distal end of the conduit providing a flow of oxygen towards an analytical flame; (5) a detector port positioned at the distal end of the conduit; and (b) a light detector configured to detect emissions passing out through the detector port.
