Contact Volume

Although differences in the methods of the studies shown in Table 26 (time of contact, volume of solution, temperature, etc.) do not allow for direct comparisons, the data presented suggest that the teachability of DEHP is highly dependent on the nature of the pharmaceutical formulation. The question of migration of DEHP into solutions is relevant not only to lipophilic vehicles but to drugs such as pacli-taxel and etoposide, which are able to extract much more DEHP than simple Upophilic lipidic emulsions do. 

Earlier we described the area bound by A-B-C-D and noted it to be proportional to the reciprocal of the value of the integral for Ntu. This value defines the characteristics of the tower, and it is clear that the lower the area, the higher the value KaV/L, i.e., high contact area (a) and high contact volume (V) therefore, high investment cost. The reduction of the investment cost and, therefore, the increase of area A-B-C-D, can be achieved by increasing... 

Different vertical loads can be applied to a bulk solid sample of known mass, and compression of the sample is recorded electronically (Thomson, 1997). With these data, powder contact volume versus compressive force or stress can also be represented. Bulk density of a solid is a function of consolidation stress and changes during flow as the stress changes. Because the mass consolidating load and volume are known, the relationship can be plotted as shown in Figure 6. 

For solid samples, it may be necessary to change their physical state. This is achieved by grinding the solid to a powder as fine as possible, or dissolving or dispersing the solid into a liquid. In the first case, the contact volume of the solid is increased in order to establish a better partition between the volatile substance and the headspace gas however, it is preferred to dissolve the solids in a liquid, because equilibrium is achieved faster this way, and is also more reproducible on top of that, liquid samples are easier to work with (Slack, et al., 2003).

Kindly send the final and checked Word and PDF files of your paper to the Contact Volume Editor. This is usually one of the organizers of the conference. You should make sure that the Word and the PDF files are identical and correct and that only one version of your paper is sent. It is not possible to update files at a later stage. Please note that we do not need the printed paper.
