Postnova model 1650 FFF Smart Stream Splitting (S3) module

FFF Smart Stream Splitting module

Model 1650 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.

Model 1650 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.

Unique features:

• Special flow splitter for enhancement of sensitivity by factor up to 5
• Flexible use within any kind of sequence of runs
• No changes to system hardware necessary
• Ideal when concentration signals are insufficient
• Can be used with any AF2000 series FFF system
