Abstract
The invention relates to a method of determining a permeation property of hollow-fibre membranes wherein the permeation property of the hollow-fibre membrane is determined on a hollow-fibre membrane bundle which has been introduced into a housing and has terminally open hollow-fibre membranes at a first end of the hollow-fibre membrane bundle and terminally closed hollow-fibre membranes at a second end of the hollow-fibre membrane bundle. The invention more particularly relates to a method of determining the ultrafiltration rate and/or the ultrafiltration coefficient of hollow-fibre membranes.
Claims22
A method of determining at least one permeation property of hollow-fibre membranes, comprising the steps of:
- (a) providing a hollow-fibre membrane bundle comprising a multiplicity of hollow-fibre membranes having a first end and a second end, wherein the lumens of the hollow-fibre membranes at the first end of the hollow-fibre membrane bundle are terminally open, and at the second end of the hollow-fibre membrane bundle are terminally closed,
- (b) providing a housing for receiving the hollow-fibre membrane bundle having the first end and the second end, wherein the first end has at least one liquid inlet,
- (c) introducing the hollow-fibre membrane bundle into the housing, wherein the first end of the hollow-fibre membrane bundle having the terminally open lumens of the hollow-fibre membranes is oriented towards the at least one liquid inlet at the first end of the housing,
- (d) determining a permeation property of the hollow-fibre membranes.
