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.
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 method of determining the amounts of two or more compounds in a liquid, said method using a first technique to determine the total amount of substantially all compounds present in the liquid and using a second technique to determine the amount of at least one of the two or more compounds present in said liquid, the measurement obtained by the second technique being calibrated by the measurement obtained from the first technique, such that the total amount of said two or more compounds present in the liquid can be determined using the data obtained by said second technique over a period of time based upon an assumption that the relative proportions of said two or more compounds present does not change significantly over said period of time.
