摘要： PURPOSE:To perform highly accurate quantitative analysis in a short time by forming an assumed concentration operation matrix obtained by the combination of reference spectra in a plurality of components of known concentrations, and using the matrix. CONSTITUTION:A comparing sample or a sample to be measured is contained in a cell 12. Infrared rays are emitted from an infrared-ray source 7 on the cell 12, and the interferogram of the comparing sample or the sample to be measured is measured. In a data processing part 2, the interferograms are added and averaged. The added and averaged output undergoes Fourier transformationa at a high speed. The spectrum with respect to the component to be measured is operated based on the detected output of the Fourier transformation. A memory part 4 specifies the group of wave- number points of predicted arbitray gas out of a reference spectrum group 5 having the known concentrations. After the spectrum of the component is obtained, an assumed concentration operation matrix is stored by using a calibrating matrix. Therefore, it is not necessary to store the reference spectra of a plurality of components in, e.g. an analyzer. It is not necessary to form a concentration operation matrix within an apparatus. Therefore, the quantitative analysis can be performed highly accurately in a short time.

摘要： PURPOSE:To stably perform measurement with high sensitivity, by providing an apparatus for removing the impurity generated when ozone is generated between an ozone generator due to discharge and an analytical part into which ozone is introduced. CONSTITUTION:Moisture is removed from air K being a raw material in a dehumidifier 1 and the dried air K' is introduced into an ozone generator 5. Whereupon, a gas O' wherein a slight amount of impurity gas F is contained in ozone O is generated in the ozone generator 5 by silent discharge. When this gas O' is guided to one trap chamber 7B of a water trap 7 filled with water W, the impurity gas F larger in solubility than ozone O is almost dissolved in the water W to become HNO3 and, since ozone O is not almost dissolved in the water W, the gas reaches an ozone flow passage 12 without lowering the concon. of ozone and ozone O almost containing no impurity gas F is supplied to an NO analytical part 11.

摘要： PURPOSE:To continuously analyze samples without receiving any influence from the drift of an absorption spectrum by preparing a base line spectrum on a computer by simplifying the drift of a base line and using the prepared spectrum as part of a reference spectrum at the time of generating a concentration calculating matrix. CONSTITUTION:A base line drift itself can be regarded as a kind of interference component which makes a whole spectrum to float or sink. In addition, since a base line itself makes no absorption and has no noise, a base line spectrum is prepared on a computer and used as part of a reference spectrum at the time of generating a concentration calculating matrix. Therefore, the influence of a drift can be eliminated from a concentration-calculated value. In addition, when the base line spectrum is applied to continuous analyses; a highly accurate determinated result can be obtained. When, for example, the base line has a possibility of making absorbancy floating or sinking by +0.05, five kinds of data files respectively having floating or sinking values of =0.10, +0.05, 0, -0.5, and -0.10 are prepared.

摘要： PURPOSE:To analyze even a component to be measured having high concentration with the minimum detecting sensitivity being maintained at a constant level and to make it possible to perform continuous analysis even for a samples to be measured whose concentration change is large by automatically switching the groups of wave-number points used for the concentration computation of the component in response to the magnitude of the concentration of the component to be measured. CONSTITUTION:The group of wave-number points used for concentration computation corresponding to the concentration range based on the spectrum data obtained from a Fourier- transformation infrared spectrophotometer is used, and operation is performed. Whether the computed value can be outputted or not is compared with a threshold value. When the concentration range which is set by the computed value is judged as adequate, the computed value is outputted as the computed value of the concentration. When the range is not adequate, the concentration range is changed and set at the adequate value. The operation is performed again based on the absorbance of the group of the wave-number points for the corresponding concentration computation. These computation, judgment and change of range are all performed with computers automatically. Only the result of the concentration computation based on the group of the wave-number points for the most adequate concentration computation is always outputted in this way.
