摘要
An improved photoionization detector has a sweep gas inlet which is used to introduce sweep gas near the window of the detector's ultraviolet lamp. The detector's chamber has a vent which allows selective removal of spurious analyte. The detector is adapted to have directly mounted on it, a second detector. Sweep gas used to keep analyte away from the window may be used as a reagent in the second detector. In addition, a means for regulating the ionization lamp voltage is disclosed which prolongs lamp life expectancy.
