Reduced Plate Height indicator

Indicates the reduced plate height of the separation.

Calculation

The eluent viscosity is calculated by the following equation, reported in Chen, H.; Horvath, C. Anal. Methods Instrum. 1993, 1, 213-222.

where
η = eluent viscosity (cP)
T = temperature (°C)
Φ = volume fraction methanol

Remarks

The eluent viscosity is useful for calculating the backpressure and the average diffusion coefficient.
