| 摘要 |
An apparatus for determining the total amount of two or more substances in a liquid, at least one of said substances comprising a fluorescent substance, said apparatus comprising: a mass spectrometer device; a fluorometer device; and a processing means; wherein said mass spectrometer device is adapted to obtain a periodic measurement of the total amount of said two or more substances in the liquid, said fluorometer device being adapted to detect the fluorescent response of said at least one fluorescent substance in said liquid to an excitation signal, said processing means being programmed to determine a calibration factor by comparing a measurement obtained by the fluorometer device with said periodic measurement of the total amount of said two or more substances present obtained by the mass spectrometer device, the processing means subsequently using said calibration factor to determine measurements representative of the total amount of both fluorescent and non-fluorescent substances present in the liquid based upon the fluorescent response detected by the fluorometer device. |
