Believing in raw data?
In general, the purity of a DNA solution is easily defined using purity ratios. It is possible that reduced purity may be attributed to the fact that the sample is solubilized in water instead of in buffer. Since water and buffer have different properties, the absorbance of the sample being measured will be affected by this disparity.
For this reason, the BioSpectrometer is capable of recording a “Purity Scan” which displays the absorbance properties of a sample graphically, thus enabling fast and simple visual quality control.

In addition, all important raw data pertaining to the DNA sample are displayed in table format. The table optionally lists the purity ratios (A260/A230 and A260/A280), the absorbance values (raw data), as well as the background absorbance, e.g. at 320nm.
Thus, the two display formats complement each other perfectly to allow for an evaluation of the quality of a DNA sample.
