The instrument assumes that all absorbance at 260nm is due to nucleic acids, meaning that contaminants like carbohydrates or phenol can artificially inflate concentration readings. Understanding the Key Metrics and Outputs When a sample is measured, the Nanodrop display presents a clear set of data points.

Its primary role is in nucleic acid quantification for downstream applications like PCR, cloning, sequencing, and microarray analysis, where precise input is essential. For samples with significant cloudiness or particulates, the spectrophotometric measurement may be less accurate, making the fluorometric method a better alternative.
Crucially, the ratio of absorbance at 260nm to 280nm (A260/A280) provides a quick snapshot of purity, indicating the presence of protein or phenol contamination. The resulting A260/A280 and A260/A320 ratios are then compared against established purity ranges to give an immediate quality assessment.
