Basically, during the hardening phase, the concrete was not able to completely fill the required volume.
The eluent was prepared freshly each day, and the required volume depended on the number of samples (200 µL/sample).
An instance of voltage received, i.e., 854 mV, is used to compute the required volume as shown in Figure 14.
Usually, Devinny says, biofilters have to be very large to get the same efficiency as chemical scrubbers, but this technique shrinks the required volume.
The solutions were completed to the required volume by the mobile phase and were subjected to the chromatographic analysis under optimum conditions.
Latent heat storage using phase change materials (PCM) presents an advantage in comparison to conventional sensible heat storage systems due to the required volume.
For one example of collimating 2.615 MeV gamma rays, a quartic collimator reduces the required volume by over 70% from a standard cylindrical collimator.
However, in some applications the required volume flow of fluid is so large, that turbulent flow can no longer be avoided.
A 10-ml portion of this solution was transferred into a 50-ml calibrated flask, and 0.1 mM NaOH containing 50% aqueous methanol was used to dilute the contents of the flask to the required volume.
"My clear conclusion is that we do not yet have the appropriate range of pathways available or the capacity to deliver the required volume and range of teaching," he said.
The first 2 mL were discarded and the required volume collected into plastic tubes containing 0.27 mL 0.109 M sodium citrate (Becton Dickinson, Plymouth, UK) or heparin (68 IU, Beckton Dickinson).
