TīmeklisSo the nanodrop shines light of those different wavelengths through your sample and records how much light got absorped at each one. It uses a built-in equation to convent absorption at 260nm into a DNA concentration. Those other ratios give you a rough idea of how pure your sample is, and what kinds of contaminants you might be dealing with. http://www.u.arizona.edu/%7Egwatts/azcc/InterpretingSpec.pdf
