摘要： An atomic absorption photometer in which an electrical signal representative of the beam of light passed through a flame is integrated by an integrator, and an electrical signal representative of the emission spectrum peculiar to the flame is differentiated by a differentiator to be utilized as an integration starting signal. The photometer is provided with means for generating an electrical signal in response to the introduction of a standard sample into the flame and ceasing to generate the electrical signal in response to the introduction of a sample to be examined into the flame due to the fact that the emission spectrum of a particular substance in the sample to be examined appears when it is introduced into the flame. The photometer is further provided with means which generates an electrical signal in response to the application of both the electrical signal generated by said means and the output from the differentiator thereby offering a zero adjustment of the light absorbance.

摘要： In the measurement of a small amount of organic contaminants (pollutants) in clean (treated) water with the aid of fluorescence analysis, the peak value of a Raman light is measured. The fluorescence intensity is then standardised with the aid of the peak value as reference, thereby facilitating accurate measurement without the influence of equipment factors.

摘要： PURPOSE:To enhance the sensitivity of measurement and the resolution of mass spectrometry by effectively eliminating through a simple method noise elements such as photons generated from an ionization source and contaminating elements such as nonionized molecules and droplets. CONSTITUTION:An ionization source 6 and a mass spectrometry portion 3 are nonlinearly disposed and an ion reflector electrode 1 which functions as a mirror to reflect ions is interposed between the ionization source and the mass spectrometry portion and the track of the ions generated at the ionization source 6 is curved by the ion reflector electrode 1 so that the ions impinge on the mass spectrometry portion 3. A deflector 2 is provided in front of the mass spectrometry portion 3 to change the ion track again.

摘要： PURPOSE:To permit analysis of a high-concn. sample by obtaining an atomic absorbancy versus time curve, preliminarily determining the time width at 1/2 the max. value of the absorbancy of that curve, measuring the arbitrary absorbancy of a sample and making computation. CONSTITUTION:A sample is heated by a graphite tube to form atomic vapor and a luminous flux is passed through the vapor. The absorbancy by the atomic vapor is detected and the absorbancy versus time curve P is is obtd. The half- amplitude level (w) of the time at the absorbancy of 1/2 the max. value (h) of the absorbancy in the absorbancy versus time curve P is constant regardless of an element concn. The arbitrary absorbancy (k) and time width (v) of the absorbancy versus time curve P is determined with respect to a desired element and the true max. value (h) of the absorbancy is computed by the equation to analyze the concn. The computation is made by using the half-amplitude level (w) even if the concn. of the desired element is high and the high absorbancy of the absorbancy versus time width curve rolls over; therefore, the measurable upper limit concn. of the element is increased.

摘要： PURPOSE:To make exact measurement by executing normalization with the peak value of Raman light as a reference. CONSTITUTION:The ray radiated from a light source 1 is divided by an optical pumping side spectroscope 2 and is irradiated to the pure water of a sample cell 3. The fluorescence and Raman light generated from the pure water are made incident on a fluorescent side spectroscope 4. The light divided by the same is detected by a detector 5. The spectroscope 4 has a wavelength scanning function, by which the intended wavelength range is scanned. The spectral intensities at the respective wavelengths are stored in a storage device 6. The normalization over the entire part of the spectra is executed by an arithmetic unit 7 with the peak value of the Raman spectra of the water as the reference when the scanning in the intended wavelength region ends. Since the fluorescence is measured with the Raman light intensity as a reference in the above- mentioned manner, the influence by equipment factors such as the intensity of the light source lamp and detector sensitivity is eliminated and the concn. of the org. impurities in the pure water is exactly measured.
