when done.

Calibrating from Solutions of Known Concentration

a. Insert a sample for which the concentration is known into the spectrometer.

b. Select Calibrate from solutions of known concentration, insert samples into the

spectrometer for which you know the concentration and use that as a basis for computing the

concentration of the unknowns. Then, click
