In addition, comparative genomics analysis also identified some variations up-stream of solvent-relevant genes (Table 3), which could potentially affect expression level of these genes.
Next, the analytes were eluted from the SPE column with LC solvent B at 1 μL/min and were then transferred to the trap column by mixing it with another stream of LC solvent A through the port P3 (20 μL/min).
The passive microfluidic mixer (i.e., herringbone structures) enables efficient mixing of two streams and thus prevents heterogeneous streaming of organic solvent from the SPE eluent, allowing the analytes to be enriched on the trap column efficiently.
The solvent was subsequently evaporated under a stream of nitrogen and residual solvent removed under high vacuum for 1 day.
The successful application of zeolite A membranes in the industrial market has thus far been restricted to the pervaporative dehydration of solvent streams in the pharmaceutical and engineering industries.
For process design and optimization, the operation pathway including two-step solvent injections at different temperature, the supercritical recovery of solvent from DAO stream and the solidification of asphaltenes by depressurization, as well as other important issues have been addressed.
The positive control, amphotericin B (0.002 μg/μl) equivalent to 0.01 μg per spot was applied on the test plate in triplicate followed by removal of solvent using a stream of cold air.
Chloroform was evaporated with a stream of nitrogen, leaving a thin lipid film, which was redried under a stream of nitrogen to remove residual traces of solvent [16], [17], [18], [19], [20].
Sample volume was reduced to 50 μL by drying with a gentle stream of nitrogen, and the remaining solvent was primarily composed of water as it was the least volatile solvent in the MeOH/EtOH/H2O extracts.
The solvent was subsequently evaporated under a stream of nitrogen at 45°C and residual solvent removed under high vacuum for 1 day.
