How to Calculate Concentration Using Absorbance
- https://sciencing.com/calculate-concentration-using-absorbance-7153267.html
- Step 1. Construct a calibration plot of absorbance on the y-axis and concentration on the x-axis for the standard solutions. The data points should fall along a reasonably straight line. Two data points represent the absolute minimum, and more is better. Step 2. Draw a best-fit straight line through the data points an… See more
