What is the purpose of collimating slits in a spectrophotometer and how do they affect the accuracy of the measurements?
The purpose of collimating slits in a spectrophotometer is to ensure that only a narrow and parallel beam of light enters the instrument. This helps to improve the accuracy of measurements by reducing stray light and ensuring that the light beam is properly focused on the sample. The collimating slits help to minimize interference and ensure that the measurements taken are precise and reliable.

What is the purpose of a slit in a spectroscope?
The purpose of a slit in a spectroscope is to limit the amount of light entering the instrument, allowing for better resolution and the ability to isolate specific wavelengths for analysis. The slit helps to reduce background noise and enhance the overall spectral quality of the measurements.
What purpose does blank serve in a spectrophotometer?
In a spectrophotometer, a blank serves as a reference to account for any absorbance due to the solvent or other components in the sample that are not of interest. It typically contains all the components of the sample except the analyte, allowing for baseline correction. By measuring the absorbance of the blank, the instrument can subtract this value from the absorbance of the sample, ensuring that the results reflect only the absorbance due to the analyte of interest. This improves the accuracy and reliability of the measurements.
