What are the parts of a spectrophotometer and their functions?
Understand the Problem
The question is asking for an explanation of the various parts of a spectrophotometer, detailing their functions and roles in the device's operation.
Answer
Spectrophotometer components: light source, diffraction grating, exit slit, detector, cuvette, cuvette chamber, power switch, 100% transmittance control.
The parts of a spectrophotometer and their functions are:
- Light Source: Provides illumination for analysis.
- Diffraction Grating/Prism: Separates light into wavelengths.
- Exit Slit: Allows selected wavelength through.
- Detector: Converts light into transmittance/absorbance.
- Cuvette: Holds the sample.
- Cuvette Chamber: Compartment for cuvette.
- Power Switch/Zero Adjust: Turns on device, sets baseline.
- 100% Transmittance Control: Calibrates maximum transmittance.
