Membrane chromatography sterilization

Filtration using membrane filters with a pore size of 0.45 xm is the most common sample pretreatment procedure for ion chromatography. For biologically active samples, the use of sterile filters with a pore size of 0.2 j,m is strongly advisable. Filters are made either from PTFE, polyvinyldienedifluoride (PVDF), or similar material. Cellulose filters are generally unsuitable. Filter materials differ in pore size, porosity, filtration speed, compatibility with acids, abuse, and organic solvents, as well as in their adsorption properties and blank values. [Pg.2107]
