Selecting the right calibration standard involves several considerations:
- Matrix Compatibility: The standard should closely match the matrix of the sample being analyzed. For example, if analyzing a gas-phase reaction, a gas standard would be more appropriate. - Concentration Range: The standard should cover the expected range of analyte concentrations in the sample to ensure accurate calibration across the entire dynamic range. - Stability: The standard should be stable over time to avoid degradation, which could lead to inaccurate calibration.
