METHOD OF AND APPARATUS FOR DETERMINATION OF TRACE CONSTITUENTS BY SIMULTANEOUS MEASUREMENT OF PHOTOLUMINESCENCE AND PHOTOACOUSTIC SIGNAL |
摘要 |
A method of and an apparatus for simultaneous determination of constituents are disclosed in which a solution containing trace constituents is irradiated with an intensity-modulated electromagnetic wave having a predetermined wavelength, a photoacoustic signal and radiation from the electromagnetic-wave irradiation trace constituents are detected together with the emission spectrum thereof. The concentrations of the trace constituents are calculated from the magnitude of the photoacoustic signal, the intensity of the radiation, and calibration curves each formed for known concentrations of one of the trace constituents, and the trace constituents are identified by the above emission spectrum. |
