Consider a 100 step countercurrent distribution of solutes A \& B with distribution coefficients DA=1&DB=0.6. Suppose the volumes of mobile and stationary are equal. If fractions 2840 and 4460 are each pooled find the % recovery and purity of each solute. A. Tubes 4460 have 68.21% recovery of 88.66% pure A Tubes 28 - 44 have 94.38% recovery of 97.22% pure B B. Tubes 4460 have 86.21% recovery of 90.54% pure A Tubes 2844 have 67.38% recovery of 96.72% pure B C. Tubes 4460 have 96.21% recovery of 84.04% pure A Tubes 2844 have 94.12% recovery of 92.22% pure B D. Tubes 4460 have 72.36% recovery of 92.14% pure A Tubes 2844 have 87.52% recovery of 95.12% pure B
