- why does the choice and use of a blank matter for Spectrophotometry?Question 9 The basic spectrophotometer is composed of four components. Which component listed below is NOT one of the four? beam splitter monochromator detector O light source" Spectrophotometric analysis" refers to methods that are based on light absorbance. O True False
- A solution with a known concentration equal to 3.4 mM gave an absorbance reading of 0.820 in a spectrophotometer. Assuming that there is a linear relationship between concentration and absorbance up to a concentration of 4.0 mM, what would the absorbance reading be for a solution with a concentration 2.2 mM?What is the significance of the highest value of absorbance in spectrophotometry?Chemical dyes are used to increase resolution of objects. True False
- The maximum number of spectra that can be recorded per second by ToF-MS is limited by the time taken by the slowest ions to go from the source to the detector. If the slowest ion took 45.6 microsecond to travel, at what frequency could you record spectra if a new extraction cycle were begun each time this heaviest ion reached the detector? 30000 spectra/s 10000 spectra/s 11000 spectra/s 500 spectra/s 22000 spectra/sKiko wants to determine the concentration of an unknown solution which produces a green solution. However, the spectrophotometer he uses doesn't have a function to determine the analytical wavelength of the solution. What is the most probable analytical wavelength he can use for the experiment? Refer to the color wheel below.Why would a chemist using a spectrophotometer need to perform both a scan across all wavelengths and a scan at a specific wavelength?
