PN1650 Smart Stream Splitter

PN1650 Smart Stream Splitter

The PN1650 Smart Stream Splitter (S3) module is a microprocessor-controlled metering pump which allows precise and automated outlet splitting of the eluent stream leaving the FFF channel. This unique proprietary S3 technology has been exclusively developed to offer an advanced option for FFF researchers to increase sensitivity in FFF detection currently available for AF2000 Flow FFF systems. Together with an AF2000 double outlet channel cartridge detection levels can be increased by a factor between two and five without any further injection of additional sample into the FFF separation system.

Working Principle

The PN1650 Smart Stream Splitter is used as an additional module for any AF2000 series FFF system. It perfectly allows the specific removal of laminar „sample-free“ eluent streams from the upper region of the FFF channel via a first outlet. At the same time, the „sample-containing“ laminar flow streams that are located in the lower region of the channel, exit the channel via a second outlet at the end of the channel and are transferred directly to the connected detectors.

Typical Applications

Smart Stream Splitting (S3) is ideally suited and often employed when low concentration samples are investigated. Most applications come from the area of environmental, protein and polymer research where even the highest sensitivity detection can be insufficient and where large volume injections of diluted sample systems are standard. In these cases the S3 technology can make the difference, especially when employed together with Postnova‘s unique FOCUS technology and flexible FFF channel cartridges. Smart Stream Splitting can be used within different runs of a total sequence and allows to change the eluent outlet split ratios and to customize and optimize
conditions for each run differently.
