The supernatant was transferred to a pear-shaped flask; then the
residual sediment was ultrasonic-extracted again with 15 mL n-hexane: dichloromethane (3: 1 V/V) as described above.
The relation between the
residual sediment density and the sediment depth is plotted in Figure 5.
Residual sediment from the subsamples was heated at 550 [degrees]C for 4 h for measurements of sediment organic matter content as loss on ignition (Heiri et al.
Measurements of the
residual sediment and snowpack were obtained after water levels had receded in late June 2005.
Sweep to the floor any
residual sediment that falls from the ladle onto the melt deck.
The assessors also examined the mouth coating characteristics, viscosity, powdery mouthfeel and astringency as well as the amount of
residual sediment in the glass.
The whole system; trough, tray, sampler pipe, and bucket was flushed with clean water after each sample collection to avoid the error caused by the presence of
residual sediment. The samples were dried in an oven.
