A spectrophotometer is an instrument which is used to measure the intensity of electromagnetic radiation at different wavelengths. Important features of spectrophotometers are spectral band with and the range of absorption or reflectance measurement. Then, add the solute which would be the blank for the experiment. 2  It is important not to add water to the blank so that it wonât affect the accuracy of the results. 3  As a next step, the spectrophotometer is set to the desired wavelength. 4  Insert the blank cuvette, making sure that the arrow is aligned each time.
A spectrophotometer measures the intensity of a light beam before and after it passes through a sample and compares these two intensities. The Spec 20 reports two types of measurements: percent transmittance and absorbance.Percent transmittance is the ratio of the intensity of the light passing through the sample to the intensity of the light shining on the sample multiplied by 100%.Absorbance is the log of the transmittance. The Spec 20 can measure absorbance and transmittance over a range of wavelenghts.You must select a wavlength and calibrate the instrument at that wavelength before making any measurements.bsorbance is the log of the transmittance. The Spec 20 can measure absorbance and transmittance over a range of wavelenghts. You must select a wavlength and calibrate the instrument at that wavelength before making any measurements.
