Passive diffusion bag

Fig. 9 Passive membrane dialysis performed with catalyst G0-20 in a Michael 1,4-addition reaction. A Upper phase = Et20 + catalyst + product, lower phase = aqueous HC1 + side-products. B Organic phase addition into the membrane pocket . C Diffusion of the product into the beaker (charged with pure Et20), while the catalyst remains retained inside the tea-bag ...

The semipermeable membrane device (SPMD) is a thin-walled, layflat polyethylene tubing that contains approximately 1 g of a lipid, triolein (600 molecular weight), that cannot diffuse through the polyethylene bag. The SPMD was invented by Huckins and co-workers (1993). The principle of the SPMD is that it is a passive sampler for nonionic organic substances in water... [Pg.324]
