What are the advantages and disadvantages of decreasing monochromator slit width?
The advantage of decreasing monochromator slit width is enhanced ability to resolve closely spaced spectral peaks.
The disadvantage is additional noise as a result of less light reaches the detector.

The true absorbance of a sample is 1.000, but the mono chromator passes 1.0% stray light. Add the light coming through the sample to the stray light to find the apparent transmittance of the sample. Convert this answer back into absorbance and find the relative error in the calculated concentration of the sample.
Describe the role of each component of the spectrophotometer.
Would you use a tungsten or a deuterium lamp as a source of 300-nm radiation? What kind of lamp provides radiation at 4-mm wavelength?
Explain how the following detectors of visible radiation work: (a) photomultiplier tube, (b) photodiode array, (c) charge coupled device, and (d) image intensified charge coupled device.
