Explanation of the Incorrect Statement
The statement that "A conventional mass spectrometer employs high energy UV radiation" is incorrect.
Understanding Mass Spectrometry
- Mass spectrometry is a technique used to measure the mass-to-charge ratio of ions.
- It does not primarily use UV radiation; instead, it often employs methods such as electron impact, chemical ionization, or electrospray ionization to ionize samples.
Key Techniques in Mass Spectrometry
- **Electron Impact (EI)**: Utilizes high-energy electrons to ionize gaseous samples.
- **Chemical Ionization (CI)**: Involves ionizing a reagent gas, which then reacts with the sample.
- **Electrospray Ionization (ESI)**: Common for large biomolecules, where the sample is sprayed into a fine mist.
Why UV Radiation is Not Used
- UV radiation is more associated with techniques like UV-Vis spectroscopy, which analyzes absorbance and concentration of compounds.
- In mass spectrometry, the focus is on generating ions from the sample, which is not achieved through UV radiation.
Other Options Explained
- **Option B**: Correct. Mass spectrometers do not use spectrophotometric detectors.
- **Option C**: Correct. Mass spectrometry can analyze samples of varying purities.
- **Option D**: Correct. Mass spectra display signals for charged species, not uncharged radicals.
Conclusion
In summary, mass spectrometers do not utilize high-energy UV radiation for ionization, making option A the incorrect statement among the provided options.
