Single Element Standard Solution
A single-element standard solution is a solution containing a compound of a specific element, whose concentration has been precisely determined and which is soluble in a specific solvent. Typically, the concentration of a single-element standard solution is expressed as molar concentration to ensure its accuracy and comparability.
Multi-element Standard Solution
Multi-element mixed standard solutions are standard solutions containing multiple elements, used in quality analysis and instrument calibration. Their main property is compositional diversity. Multi-element mixed standard solutions contain various elements, and can be customized to analyze different combinations of elements as needed.
