Figure 5From: The Deuterator: software for the determination of backbone amide deuterium levels from H/D exchange MS dataExtracted ion chromatogram. The averaged ion intensities for a centroid mass ± 0.5 (Da) are displayed across all scans allowing the user to graphically determine the retention time range that will produce the best data results. In the case above, the co-added data may yield an isotopic profile with a higher signal-to-noise ratio if the retention time start and end positions were reduced slightly.Back to article page
