Averaging multiple scans of data contributes to PDF profiles that have a reduced amount of noise. A single sample of ACP is presented as a single scan, an average of five and an average of 20 scans. The noise in the data is significantly reduced between one and five scans. There is a slight reduction in noise between five and 20 scans. Averages beyond 20 scans did not have a significant reduction in noise. Each scan represents 1 min of data collection, indicating noise reduction is optimized with at least 20 min of collection time. |
