← ScienceWhich consequence results when the gas constant used in Van Deemter equation is inaccurate for chromatographic column optimization?
A)Incorrect optimal temperature prediction✓
B)Faulty carrier gas flow control
C)Unreliable diffusion coefficient calculation
D)Spurious changes in retention index
💡 Explanation
Incorrect gas constant compromises the computed plate height during chromatography because eddy diffusion depends on accurate parameterization within mass transport; therefore, optimal efficiency cannot be found, rather than only affecting flow because retention is dominated by the stationary phase chemistry.
