Tips include what to do if insufficient sample migration occurs and why you should look for contamination patterns in graph.
Flick Screen Tape to eliminate bubbles.

If insufficient sample migration occurs, dilute samples to a lower buffer salt concentration.

Figure 1: Illustrating the differences in quality of input DNA. Blue trace is poor quality FFPE sample with a DIN of 2.3. Green trace is good quality FFPE sample with a DIN score of 5.6. Orange trace is a good quality whole blood DNA sample with a DIN score of 6.5.
Bring all reagents to room temperature.

If your reading is too high, dilute samples.

If you reading is too low, protect from light which diminishes sample signal and check standard tube readings for accuracy.

Carryover contamination may decrease or increase readings, look for contamination patterns in graph.

Check blanking reagent, be sure to use a similar pH and ionic strength as samples solutions to maximise Nanodrop accuracy.
