The water-immiscible extractant was collected by centrifugation, dried under low pressure, reconstituted in methanol water mixture (1 1), and injected into a HPLC system for the determination of CPAs.
For scanning electron microscope (SEM) analysis, samples were completely dried under low pressure and then were transversely cut with a razor blade, producing a fracture rather than a clean cut.
Instant teas are produced from black tea by extracting the liquor from processed leaves, tea wastes, or undried fermented leaves, concentrating the extract under low pressure, and drying the concentrate to a powder by freeze-drying, spray-drying, or vacuum-drying.
The material 2-hydroxyethyl methacrylate (HEMA; ACROS, Fair Lawn, NJ, USA) was dried over molecular sieves (type 4A) for 24 h followed by distillation under low pressure.
Following the digestion, the digest was dried in a speed-vac concentrator (Thermo-Fisher Scientific Model SPD121P-120) at 25°C under low pressure of <10 mTorr.
An injection under low pressure causes less damage than an injection under high pressure.
The growth occurs under low pressure (below atmospheric pressure).
Make sure to spray under low pressure.
Life builds most things at low temperatures, in low toxicity and under low pressures.
After drying under reduced pressure, cartridges were eluted with 3 ml MeOH/water (80/20, v/ v).
The methodology is applied to the results of drying experiments under low and normal pressure conditions and verified by a Finite Element (FE) analysis.
