<p>Concentration of a solute in a solution is determined. Light from a light source (105) is received at a chamber (125) containing the solute and the solution. The light is transmitted along an optical path length of the chamber (125), through the solute and the solution, and output from the chamber (125). The light output from the chamber (125) is detected by a detector (180). The optical path length of the chamber (125) is selected to optimize sensitivity of the detector (180). The concentration of the solute in the solution is determined based on the light received by the detector (180).</p> |
