Question
A UV-Vis spectrophotometer measures:Group of answer choicesthe emission of light from a sample.the absorbance of light from a sample.the splitting of light produced by a sample.directly the concentration of our analyte.
Solution
A UV-Vis spectrophotometer measures the absorbance of light from a sample. This instrument works by passing a beam of light through a sample and detecting the amount of light that is absorbed by the sample. The absorbance is then used to determine the concentration of a specific substance in the sample.
