For the dsDNA and Protein A280 applications, the NanoDrop One software monitors all
sample measurements for the presence of contaminants or other anomalies that may affect the
measurement. Examples of monitored characteristics include:
• absorbance ratios, which indicate the presence of compounds that may interfere with
sample measurements (also referred to as “purity ratios”). For more information, watch
the multimedia training What is a Purity Ratio?.
• bubble check, which looks for bubbles or other reflective materials in a sample or blank.
For more information, watch the multimedia training Effects of Bubbles in Samples.
If technical information is available, the “information” icon appears to the left of the
measurement results.
Tap the icon to view the information.
Here are results from a nucleic acid analysis for which two measured purity ratios are below
the expected value and the sample contained enough bubbles to possibly affect the
measurement results.
