10 Questions
The double beam spectrophotometer is more expensive than the single beam spectrophotometer.
False
The single beam spectrophotometer requires the reference point (blank) to be reset frequently when measuring a series of samples.
True
The double beam spectrophotometer automatically subtracts the signal for the absorption of the reference cell from the sample cell.
True
The UV/Visible Spectroscopy Recorder can display data in the form of a computer software program that provides all the needed information, including peak area.
True
The single beam spectrophotometer is more accurate than the double beam spectrophotometer.
False
The UV/Visible Spectroscopy Recorder can display data in the form of a sensitive galvanometer to give absorbance or transmittance percentage units.
True
The UV/Visible Spectroscopy Recorder can display data in the form of an x-y recorder to scan the absorption or transmittance spectrum.
True
The double beam spectrophotometer has a more complex design and is more expensive than the single beam spectrophotometer.
True
The single beam spectrophotometer is more sensitive than the double beam spectrophotometer.
False
The UV/Visible Spectroscopy Recorder can display data in the form of a computer software program that gives all the needed information, including peak area, but not in the form of an x-y recorder to scan the absorption or transmittance spectrum.
False
Test your knowledge on the advantages and deviations of UV/Visible Spectroscopy, including factors affecting stability of readings, ability to correct for solvent effects, and deviations from Beer-Lambert's Law. Identify real deviations, instrumental deviations, irregular, and regular deviations.
