Interferences deuterium lamp

An UV light beam, obtained with an intensity-regulated deuterium lamp and a narrow-slit monochromator, passed through the gas phase between two perfectly aligned pin holes mounted in front of the optical windows. An EMR 541-N PM tube, with an appropriate interference filter placed immediately before it, was used in conjunction with associated electronics to continuously monitor the UV intensity as a means of measuring changes in concentration of the reagent gas. [Pg.112]
