4 Reagents and solutions

4.1 water, distilled water, ion exchange purification system. Before use test the water content of the analyte, is guaranteed under the detection limit. 4.2 nitrate (ρ1.42g/mL), superior grade pure or high purity, after sub-boiling distillation purification. 4.3 nitric acid (11). 4.4 hydrofluoric acid (ρ1.16g/mL), superior grade pure or high purity, after sub-boiling distillation purification. Warning --- toxic hydrofluoric acid, and corrosion Resistance, wear gloves when operating, to prevent skin contact. 4.5 single element standard stock solution. specific preparation see Appendix B. More than 4.6 element mixed standard stock solution Direct dispensing single element standard stock solution (4.5) formulated the following multi-element mixed standard stock solution, and mixing a commercially available multi-element standard Quasi stock solution was diluted to give (see Table 1). Note. When a multi-element standard stock solution was prepared attention compatibility and stability elements. Original standard stock solution elements to be checked in order to avoid impurities Movies Sound standard accuracy. Good standard solution was transferred to a new distribution of pickling, virgin polypropylene bottles stored and periodically check its stability.
