Which 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.
