Spectroanalysis system

A chopperless spectroanalytical system of the double beam type in which radiation from a common source is split into reference and analysis beams. The two beams are directed along similar paths such that the analysis beam passes through an analysis region and the reference beam bypasses that analysi...

Beschreibung
Zusammenfassung:	A chopperless spectroanalytical system of the double beam type in which radiation from a common source is split into reference and analysis beams. The two beams are directed along similar paths such that the analysis beam passes through an analysis region and the reference beam bypasses that analysis region. A monochromator has two spaced aperture regions such that one aperture region provides an entrance aperture for the analysis beam and an exit aperture for a dispersed portion of the reference beam; and the other aperture region provides an entrance aperture for the reference beam and an exit aperture for a dispersed portion of the analysis beam. The beams exiting from the two exit apertures are simultaneously monitored and compared to compensate for errors dueto source fluctuations and the like.
