A soft X-ray photoionization detector

Direct current xenon-filled ceramic ionization chamber used as radiation detector in solar and astrophysical observations from rockets and satellites

IONIZATION CHAMBER↗

Improved photoionization mass spectrometer

Improved spectrometer for gas analysis lessens the intensity problem that occurs in obtaining dispersed ultraviolet radiation. A filter, consisting of a selectively transmitting gas cell, a thin film or mirror, or a predispersing grating, alleviates problems of interference from higher-order spectral lines and from scattered ultraviolet light.
