I got a really high value for the 260/280 ratio on a nanodrop. I am not sure if I am just interpreting my data wrong, but my results were:

Nucleic acid concentration: 1.7 ng/uL

A260: 0.035

A280: 0.005

260/280: 7.44

260/230: 0.05

Sample type: DNA

Factor: 50.00

The doctoral student that was helping me run the nanodrop said my sample was fine and fairly pure, but I am not sure how he came to that conclusion given the 260/280 ratio.
