Specify the spectral characteristics and concentrations of the absorbers in the four cell by typing values into the table (cells C9 .. F13). Use the slider above to change the wavelength of the instrument. Click on the buttons on the left to change the cell path length and lamp type. Click on one of the four cell buttons (#1 ... #4) to change the cell contents. Click the Auto-zero button to zero the instrument on the current cell contents. Click the Read button to take another reading of absorbance. Click on the Statistics button to take 30 readings automatically (without removing and replacing the cell) and calculate the mean (average), standard deviation, and percent relative standard deviation of the absorbance.
