- state if true or false 1. Prior to a fixed point or wavelength reading, spectral scanning can be done to determine the maximum absorbance wavelength of a sample. 2. The purpose of a diffraction grating is the same as that of a prism. 3. In any UV-VIS spectrophotometer, the light is filtered first to a single wavelength or narrow range before it hits the sample 4. In any UV-VIS spectrophotometer setup, the detector always comes right after the sample container. 5. It is necessary to set the blank before each reading even if the only difference between the sample solutions is the amount of analyte. 6. Prior to a fixed point/wavelength reading, spectral scanning can be done to determine the maximum absorbance wavelength of a sample.Why is it important for solutions to be diluted before they are run through spectroscopy?The absorbance of sample A is higher than the absorbance of sample B. Therefore, sample A has (circle the correct one) more / less dissolved solute than sample B. The absorbance is (circle the correct one) directly / inversely related to the transmittance of a sample.
