What Are Common Challenges in Elemental Composition Analysis?
Despite the advanced techniques available, several challenges can affect the accuracy and reliability of elemental composition analysis:
- Matrix Effects: The presence of other elements can interfere with the detection and quantification of target elements. - Sample Contamination: Even trace amounts of contaminants can lead to significant errors, especially in high-sensitivity techniques like ICP-MS. - Detection Limits: Some analytical methods may not be sensitive enough to detect elements present in very low concentrations. - Instrumental Calibration: Accurate calibration with standards is essential but can be challenging, especially for multi-elemental analyses.
