We. Wentworth et al., PULSED DISCHARGE PHOTOIONIZATION DETECTOR - APPLICATION TO ANALYSIS OF CHLORO ALKANES ALKENES, HRC. Journal of high resolution chromatography, 19(2), 1996, pp. 85-90
A windowless pulsed discharge photoionization detector (PDPID) is desc
ribed which uses the emission spectra from the discharge in helium and
Ar/Kr doped helium. The emission from helium is a continuum ranging f
rom 13.5-17.7 eV which ionizes all compounds except neon. The emission
from 5.4% Ar/Re ranges from 9.3-11.8 eV and ionizes most organic comp
ounds and many inorganic compounds. The emission from 1.36% Kr/He cons
ists principally of the resonance lines at 10.6 and 10.1 eV. These PDP
IDs are used to analyze a 12 component mixture containing principally
chloro alkane/alkenes. The relative responses of the PDPID combined wi
th the relative retention time can be used to qualitatively identify t
he chloro compounds.
