摘要：
We report on the uncertainty upon the concentration of NaCl in an aqueous solution, as determined from the change in intensity of the OH band within a new Raman optical sensor. The various sources of errors are considered and the standard uncertainty is calculated. The accuracy of the sensor is discussed according to the application. (C) 2011 Elsevier B.V.
