Which outcome occurs when pressure increases during high-performance liquid chromatography?

💡 Explanation

Increased pressure compresses the mobile phase, which intensifies molecular interactions due to reduced intermolecular distances—increasing the efficiency of analyte partitioning. Therefore, resolution improves at higher pressures, rather than a decrease in separation efficiency at altered selectivity or viscosity.
