What is a monochromator in a UV-Vis spectrophotometer?
Diagrams of Monochromator Set-UpsRelation to Spectral ResolutionDiode-Array Based InstrumentsThe width of the entrance and exit slits in the monochromator is one factor that directly impacts the spectral resolution of an instrument. A narrower slit improves the spectral resolution, whereas a wider slit reduces it. However, a narrower slit width will also reduce the amount of light reaching the detector per unit of time. This can result inSee more on knowledge.cphnano JASCO
