Asymmetrical Flow Field-Flow Fractionation Hardware

The AFFFF-Channel (front view)

ConSenxus Asymmetrical Flow Field-Flow Fractionation:

In 1997, ConSenxus launched the worldwide first commercial available AFFFF System. As a part of the continous system development, ConSenxus introduced 1998 the worldwide first commercial System for organic Solvents on the market. Actual developments are 2 new AFFFF techniques that further enhance customers benefits.

AFFFF is the most universal chromatographical method for all nanosize materials. Unlike other tools for polymer analysis like GPC methods, the AFFFF has no upper limit in terms of molecular size and weight.

For all who want to use AFFFF as a preparative device: CAFFFE

Recommended Set-Up of a Consenxus AFFFF-System:

The system consists of an AFFFF-channel, a valve box and a measuring and controlling unit.

The patented ConSenxus AFFFF-channel is designed in stainless steel, suitable for a very broad range of applications.

Optical control is important for an exact focusing. Therefore, the channel features a transparent PMMA plate for aqueous media and a glass plate for organic media. The system comes with 4 spacers of different thickness, 3 customised membranes, a membrane template and all necessary tubes, capillaries and fittings. For special applications we supply a variety of membranes with different cutoffs.

The AFFFF-System features additionally a WindowsNT^TM , Windows 2000, Windows XP and Windows95^TM compatible software for automatic system control. The software controls pumps and control valves, also for programmed flow gradients. In the Windows^TMenvironment it is possible to process chromatograms during data acquisition.

The unit comes with a 12 month warranty which covers both, software and hardware. Software upgrades are provided free of charge for 12 months from the purchase date. (Note: the membrane and other consumables are not covered by this warranty.)

The ConSenxus AFFFF is a device for separations in aqueous and organic media.

New combined Interface- and Valvebox: Savebox V5

The Savebox V5 interface features:

6 x 24 Bit ADC's for data acquisition (new AD-converter type!)
4 x 16 Bit DAC's for analog control
2 x 8 Bit DAC's for analog control

2 x relais outputs
2 x optocoupler outputs

2 x optocoupler inputs for startsignal or autosampler

all these I/O's are complete galvanical separated

LWL data transfer to the USB Port of the PC

new unified control schedules. Control values can be edit in the schedule or with the mouse on the graph.

Overpressure shut down at 25 bar ( standard value, this value can be change by the user)

optional: Voltage-frequency converter port i.e. for a pharmacia pump
optional: temperature control or temperature gradient with the control schedule of the AFFFF method.
optional: second miniature massflow regulator for detector flow (f.ex. for visco detectors)
New software with a lot of new methods to calculate the data.
Calculation ob lightscattering-, viscosity-, DAD, UC- or RI signals.
