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.
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.
