Coffea arabica DNAx: low concentration, low purity

 * Nanodrop ND-1000 Spectrophotometer setup
 * nucleic acid DNA-50
 * blank: 1.5 μL CE buffer
 * samples 1.5 μL


 * Results
 * All 260/230 and all but one 260/280 ratios below 1.8 (low purity)
 * Most probably poor sample quality (leaves molded, black) and samples were also unsufficiently ground.
