We switched to individual aliquots of buffer solution, prepared in single-use tubes. |
Appropriate aliquots of lipid stock solutions were placed in a vial and excess solvent removed under an argon stream. |
Sample digestion for Hg analysis was conducted separately, using 5 g aliquots of homogenized samples. |
Each sample was then divided into two aliquots which were subsequently treated separately as described below. |
The filtrate was discarded and the recovered retentate was divided into two equal aliquots. |
The cultures were divided into two aliquots, one of which was irradiated while the other one was left untreated. |
