Mixing time analysis

There is a single assumption in these measurements--namely that the antibody only quenches free ligand. This has been demonstrated specifically by flow cytometry in experiments which show that there is no quenching of ligand on the cell (3). The kinetic analysis depends on rapid interaction of ligand and antibody, which in these experiments is essentially within the mixing time. 

Hence, we see that this mixing time is also very small. However, this analysis implicity assumed that the pilot is located where the fuel vapor evolved. A pilot downstream would introduce an additional transport time in the process. 

The analysis of the collected data, identified that the ineffective judgement element of the mixing sub-process was caused by a combination of the lack of information from the mixing process, the lack of historical information about coagulating substances while mixing, time constraints and operator knowledge. 

After determination of the suitable mixing time to achieve product homogeneity, the influence of the unloading process on the homogeneity should be evaluated. Samples should be taken and sent to QC for analysis.

M 31] [P 28] The time evolution of the flow patterns in the cross-shaped micro mixer with two static mixing elements was monitored by simulation at time intervals of 50,150, 500 ps and 1 ms after application of pressure [71]. In addition to seeing the evolution of the swirling patterns, it was concluded from this analysis that at 500 ps a nearly homogeneous distribution of the mass fractions is given and at 1 ms this is indeed completed. Hence the theoretical mixing time of the mixer may be below 1 ms.
