How Does Gas Chromatography Preserve Peak Width?

Some points on how GC preserve peak width:

• Gas chromatography limits longitudinal diffusion and mass transfer resistance inside the column, preserving narrow peak widths and preventing signal overlap.
• By maintaining optimal carrier gas velocity and column temperature, the system reduces band spreading that would otherwise broaden analyte zones during migration.
• Efficient stationary phase interaction further minimizes delayed mass transfer between phases, ensuring sharper peaks and improving analytical resolution.
