The organic phase was separated and concentrated before injection of the totality of the sample in gas chromatography (GC, Thermo Finnigan Trace GC; HP-5 Agilent column).
From the histogram in Fig. 16b, c, e, f indicate Fig. 15b, c, e, f, respectively, it can be seen that, for the similar distances, they are concentrated before 0.08, and the corresponding restoration results by ESII algorithm are better; they are relatively dispersed or concentrated after 0.12, the repaired corresponding results are poor by exemplar-based image inpainting algorithm.
In this technique a rotifer suspension containing 200-300 individuals.ml-1 is immersed in a diluted oil-emulsion for 6 h, harvested, rinsed and concentrated before being fed to the predators.
The samples were concentrated before analysis by ultra-filtration (Millipore, Centricon, 5 kDa cut-off).
Then, the obtained solution was concentrated before transferring to a silica gel column.
The eluate was pooled and concentrated before it was loaded onto an S100 gel-filtration column (GE healthcare).
The solution was then filtered and concentrated before being loaded on to an AnaLogix silica column.
