Does Carbon Load Affect the Retention Times from Your Columns?

Jul 30, 2018 · The columns tested had percent carbon loads between 5% and 18%. What does affect the overall retentivity of a column is the phase ratio — which includes the pore volume and overall surface area. If columns with the same carbon load but different phase ratios are compared, the columns with higher phase ratios have longer retention times.
