Patent number: 5966676Abstract: A calibration-inability warning method in an analyzing apparatus determines in advance when the analyzing apparatus approaches a calibration-inability condition prior to entering calibration inability condition. To do so, coefficient ranges are set, and a calibration coefficient is computed. It is then determined whether the calibration coefficient is within a normal calibration range, a calibration-inability range, or a normal calibration range with no allowance. Signals are generated indicating that the calibration-inability condition is approaching when the calibration coefficient becomes a certain value in the vicinity of the calibration-inability range.Type: GrantFiled: June 26, 1996Date of Patent: October 12, 1999Assignee: Horiba Ltd.Inventors: Masahiko Fujiwara, Kiyomi Shiotani

Patent number: 5693945Abstract: An ultraviolet light source is provided on one end of a cell into which a sample gas is introduced. A beam splitter for dividing beams which have been transmitted through the cell into two optical paths is provided on the other end of the cell.
