    Sep 16, 2009Carbon load is the percent by weight of carbon on the stationary phase. It measures how much organic material has been chemically attached to the surface of silica. For a reversed phase column, more carbon load usually means more retention for nonpolar compounds. It is used to compare phases for their ability to retain nonpolar compounds, but
