In an analytical chemistry laboratory, a team of scientists is developing a novel method for the detection and quantification of trace metal ions in environmental water samples. The method involves a series of steps combining various analytical techniques. The sequence of the analysis is as follows: Water samples are first subjected to a pre-concentration step using a chelating resin to selectively bind metal ions. The concentrated metal ions are then eluted from the resin and introduced into an inductively coupled plasma mass spectrometer (ICP-MS) for detection. Simultaneously, an ion chromatography (IC) system is used to separate potential interfering ions before they reach the ICP-MS detector. Finally, isotope dilution analysis is applied to provide accurate quantification of the specific metal ions in the samples. Based on this sequence, what is the primary objective or challenge addressed by this analytical method in the detection of metal ions in environmental water samples? Options: A. Enhancing the sensitivity and specificity of metal ion detection B. Identifying the source of metal ion contamination C. Determining the organic content in the water samples D. Assessing the overall ionic strength and pH of the water samples Hints: Consider how each analytical technique contributes to the detection and quantification of trace metal ions. Reflect on the challenges encountered in analyzing trace metal ions in environmental water samples, such as low concentrations and the presence of interfering ions. Think about the importance of sensitivity, specificity, and accuracy in trace metal ion analysis in environmental monitoring. Don't use chatgpt please provide valuable answer
