Table 2:
Compressibility measurements of water and Toluene at 20° Celsius for two experiments with different column lengths. Sample names refer to the position in the cell (1-4, cell 1B in the first experiment leaked), the channel (A or B), Toluene (T) or Water (W), and forward (F) or reverse (R) speed direction Sample names from experiment 2 are prefixed with (*).
