PHOTOIONIZATION DETECTOR FOR GAS CHROMATOGRAPHY HAVING TWO SEPARATELY IONIZING SOURCES

A detector for gas chromatography using two ionization sources within a single body to separately provide ionization energy to a column gas eluent to provide electrical discharge to two or more collecting electrodes provides improved selectivity and may be so used. Use is made of combined bias/colle...

More Information
Summary:A detector for gas chromatography using two ionization sources within a single body to separately provide ionization energy to a column gas eluent to provide electrical discharge to two or more collecting electrodes provides improved selectivity and may be so used. Use is made of combined bias/collecting electrodes. The use of two ionization sources permits generation of two detector outputs from within a common body and of a common constituent flow. The ionization sources and any applicable discharge gas and dopant may be selected based on desired selectivity.
