Hey everyone, thanks for helping me out with my presentation this morning. I posted A LINK to the ppt. below. Let me know if you have any questions or comments. Thanks! Counterflow Dialysis

Air permeability (w341, 342, 344, 345) Burst Pressures (w341, 342)

This is preliminary data for air permeability in track-etched membranes for membranes with different pore radius.For comparison here is a table of the performance characteristics for TE membranes Measured data is of the same order as official TE membranes data.

I’m currently trying to compare separations between different complex protein mixture. This was my first crack at depleted human serum. This mixture has been processed so that the most common blood proteins (such as albumin and immunoglobulins) have been removed.…

I measured the I-V characteristics of our coated membranes on Wed. at RIT. JP observed the measurement. The semicon parameter analyzer in the test lab is “old” but isexactly what we need! Roughly speaking, our coated membraneshave resistance about 2k…

Last week’s production yielded six wafers, all deposited at room temperature. Here were the annealing conditions: Wafer 334, 343 – RTP @ 975CWafer 341, 344 – RTP @ 975C + FA @ 1000CWafer 342, 345 – FA @ 1000 C…

I used the EQ format to test the 100K microcons in a wet-wet trial using DI water. The below illustrates a comparison between the hydraulic permeability of the 100K microcons in a wet-dry format (from tests earlier today) vs. a…

I reran the 100K Microcon membranes using bovine albumin. This time I ran a set of four fresh membranes with DI water for a preliminary trial. Once complete I used two of the same four membranes with a 1mg/mL solution…

The permeability data is very different for films deposited at room temeperature and 400C.The 400C deposited wafers have much higher permeability and more consistent. w335 – RT w336-RT w338 -400C w340 – 400C Burst Pressures

The ‘Tong equation’ for liquid flow through a nanosieve is I refer you to the original paper for variable definitions (see page 285). For the flows that we see, this will always simplify to the much simpler equation … We…
