By applying the optimum experimental conditions, the characteristics of the method are presented in Table 2. Along the limit of detection (LOD) of a method (the lowest analyte concentration that
produces a response detectable above the noise level of the system), based on the three times the standard deviation of the blank (n = 10) and the empirical limit of quantification (LOQ) (the lowest level of analyte that can be accurately and precisely measured), was for all ions are presented in Table 2.
