PROBLEM TO BE SOLVED: To provide a method and system for detecting components in a fluid.SOLUTION: A modulated light beam is emitted from a modulated light source 202 to a fluid in a chamber 216, where the fluid comprises a liquid and a component in the liquid. An acoustic signal 224 is produced in response to the modulated light beam, and the acoustic signal is detected using a pressure sensor 236 disposed in the chamber. In one example, the acoustic signal is transmitted from the pressure sensor to a processor based module 228, and thereby at least one of a component and a concentration of the component in the fluid is determined using the processor based module on the basis of the acoustic signal. |
