摘要： The present invention relates to a method for determining the logarithmic reduction value LRV of a size-exclusion filter for a particle of a process solution, which particle is to be clarified, the size-exclusion filter being protected from a blocking adsorbing species present in the process solution by a process adsorber which is connected upstream in series.

摘要： A method and an apparatus are provided for carrying out integrity tests of at least one filter element, arranged within a filter housing, with porous filter materials. Sensors are provided for measuring the sound generated by a test fluid when it flows through the filter element. The method includes applying a test fluid to a first side of the filter materials of the filter element while maintaining a constant fluid pressure, measuring the body-borne sound and/or the vibrations caused by test fluid flowing through the filter materials by sensors, and comparing the body-borne sound and/or the vibrations with the body-borne sound and/or the vibrations of an integral, identical filter element, measured under identical conditions.

摘要： The present invention relates to a method of determining the concentration of at least one compound in a chromatography method, wherein fluctuations of the stationary phase's spatial structure due to variations of the composition of the mobile phase and/or the chromatography temperature are considered by calculating the concentration c(z, t) based on the flow velocity ν and the bulk porosity εb, which may vary due to the varying composition and/or temperature and which are determined for the varying composition of the mobile phase and/or the varying chromatography temperature.

摘要： The invention relates to a filtration device and to a method for characterizing a filter medium or a medium to be filtered. The filtration device comprises a plurality of filtration units. Each filtration unit comprises a first container, which is designed to receive a medium to be filtered, a second container, which is designed to receive a filtrate, at least one connecting line, which connects the first container to the second container, and a filter medium between the first container and the second container in order to filter the medium to be filtered. The first container is designed for the application of positive pressure thereto, and the second container is designed to receive a measurement instrument at ambient pressure.

摘要： A filtration device, in particular a disposable filtration device, has a flow path in which a filter element and an integrated flow reducer are arranged one behind the other. The flow reducer is adapted to be brought to a first operating position, which permits a defined first volume flow rate, and at least to a second operating position, which permits a defined second volume flow rate which is smaller than the first volume flow rate.
