title: [Determination of calcium concentration in water solution by laser-induced plasma spectroscopy].
abstract: With the experiment setup the calcium concentration in water solution was measured, based on a Nd: YAG Q-switched solid laser as the exciting light. The experiment results show that the concentration of calcium has a good linear relationship with its spectral intensity, the maximum relative errors of measurement are 3.79%, and the linear regression coefficients are 0. 992 87. In addition, laser induced plasma spectroscopy (LIPS) demonstrated convenient operation, and reliable and higher precision measurement of calcium concentration in water solution.
