Description
A new spectrophotometer is constructed for the measurements in the wavelength region of far ultraviolet to near infrared, that is, from 183 mμ to 1200 mμ. For the measurements in the far ultraviolet region, the monochromator can be effectively flashed by nitrogen gas. If flashed, the stray level is less than 0.1% in the wavelength of 185 mμ. A null method with a potentiometer is adopted in the photometric circuit.<BR>Transistors are used for the power supply of light sources. By these devices, the whole set becomes compact, the accuracy is increased and the reproducibility of less than 0.1% can be obtained for measured values. The results of the measurements of ammonia vapor and methyl ethyl ketone vapor show very good resolution in far ultraviolet region and certify the measurability of the apparatus below to 183 mμ.
