Experimental design and sample preparation are crucial steps in ensuring the success of XPS analysis. Researchers must consider factors such as the type of polymer, the desired depth of analysis, and the potential for sample charging. Sample preparation techniques, such as cleaning, cutting, and fracturing, can significantly impact the quality of the data obtained.
Sample Preparation Techniques
Cleaning, cutting, and fracturing the sample are important steps in sample preparation. Proper cleaning techniques can help remove contaminants and ensure accurate analysis. Cutting the sample to the appropriate size can also be important, as the size and shape of the sample can affect the XPS analysis. Fracturing the sample can be useful in exposing fresh surfaces for analysis.
