Molecular Weight Cut-Off or Pore Size

The molecular weight cut-off (MWCO) was specified by the manufacturer based on dextran experiments (see Chapter 4). The nominated pore size was estimated from the MWCO using the relation given by Wotch (1993), which is also shown in Chapter 2. The pore sizes range from 1 to 10 nm. This is based on dextran rejection and does not account for variations of retentions with molecular shape.
