140 Evolution 200 Series User Guide Thermo Scientific
The 260/230 ratio assay determines the purity of nucleic acids in the presence of phenol,
which absorbs strongly at 230 nm.
A ratio of approximately 1.8 is generally accepted as “pure” for DNA, approximately 2.0 for
RNA. If either ratio is appreciably lower, protein, phenol or other contaminants that absorb
strongly near 280 nm may be present.
The 260/230 values for a “pure” nucleic acid are often higher than the respective 260/280
values and are commonly in the range 1.8 to 2.2. If the ratio is appreciably lower, copurified
contaminants may be present.
