Q.103
Increase in pressure will increase the boiling point of the solvent. The principle is followed in
- Accelerated Solvent Extraction (ASE):
- According to the Clausius-Clapeyron relation, increasing hydrostatic pressure elevates the boiling point of liquids.
- Accelerated Solvent Extraction (ASE) (also known as Pressurized Liquid Extraction, PLE) utilizes high pressures ($10-20\text{ MPa}$ / $1500-3000\text{ psi}$) to maintain liquid extraction solvents at elevated temperatures ($100-200^\circ\text{C}$) well above their atmospheric boiling points, drastically accelerating extraction kinetics and solute desorption from solid matrices.
- Conclusion: The principle is utilized in Accelerated Solvent Extractor (Option 2).
Correct option: (2) Accelerated solvent extractor
