Measuring DNA
1. Display the appropriate DNA parameter screen and enter the initial
sample number (ID#).
2. Place the blank in the cell holder.
3. Press Zero/Base to measure the blank.
4. Place the unknown sample in the cell holder.
5. Press Run to start the measurement.
The DNA measurement screen is displayed. When the instrument is
finished measuring the absorbance of the sample, it displays the
absorbance, DNA ratio and DNA concentration similar to the example
below.
