18 Space-saving High Flow Hydrogen Gas Station
The Intelligent F-DGSi H2 gas station high fl ow generator saves space and eliminates the risks associated with storing high pressure cylinders, but also the hidden costs associated with piping connections, manometers, ordering, renting, delivering, servicing and maintaining cylinders.
The F-DGSi Hydrogen gas station high fl ow series i-FLOW -H2 STATION is able to generate up to 10 L/min Hydrogen with purity better than 99.9999% and pressure up to 16 bar (232 psi).
The i-FLOW-H2 STATION 10L (3 modules of 3.3 L/min) includes the new long life multilayer electrolytic cell with polymeric membrane (PEM) using distilled water.
The innovative gas drying system with automatic regeneration ensures the maximum grade of hydrogen purity, and is completely maintenance-free and allows continuous operation, 24 hours a day.
The exclusive cascading option allows combining multiple units for higher fl ow requirements.

The system’s internal self-diagnostic features, high visibility lighted display, internal/external leak detection and all the remote control and alarm capabilities increase lab safety and productivity.
The exclusive safety on the market to use H2 as carrier gas: don’t be afraid anymore to use H2 gas as carrier gas: thanks to our H2 sensor controlled by our H2 generator: in case of any leak inside the oven of the GC, the H2 generator will stop to produce.
The unique Remote PC monitoring in standard via RS232/RS485, USB, LAN allows to interface the unit with customer’s PC software (allows the end user to be connected with the manufacturer for remote diagnostics).

Separation and Characterisation of Complex Charged Molecules
The EAF2000 from Postnova Analytics is an innovative new simultaneous Electrical and Asymmetrical Flow Field Flow Fractionation (EAF4) system designed to enhance separation and characterisation of biopharmaceutical, environmental and nanomaterials.
EAF4 technology uniquely combines the principle of Electrical and Asymmetrical Flow FFF in just one system. In an EAF2000 system, Electrical and Cross Flow Fields are applied simultaneously across the FFF channel enabling separations by particle size and particle charge based on electrophoretic mobility. Combining these two powerful separation techniques in a single platform opens the door to characterising complex proteins, antibodies and viruses as well as environmental and charged nanoparticles or polymers that have proven intractable to other techniques.
The EAF2000 system integrates Postnova’s market-leading AF2000 Asymmetrical Flow FFF system, with an additional Electrical FFF module, special EAF4 channel and easy-to-use software platform. The new PN2410 Electrical FFF module is used to establish and precisely control the Electric Field allowing constant and reproducible separation conditions. This module and the EAF4 channel are connected to a standard AF2000 Flow FFF system which is controlled by the NovaFFF – EAF4 software which provides constant current operation and data evaluation for electrophoretic mobility calculation.
Modular in design, the AF2000 FFF system incorporates the combined experience, expertise and technological advances from Postnova Analytics’ nearly two decades of leadership in FFF. Incorporating a range of FFF modules in a single integrated system to provide universal separation, the AF2000 offers more fl exibility, better performance and more robust results than any system before. The AF2000 FFF system is available with a wide range of add-on modules, extra options and special FFF detectors, such as Refractive Index (RI), Multi-Angle Light Scattering (MALS) and Dynamic Light Scattering (DLS). All Postnova FFF modules and detectors have been especially developed for FFF and are perfectly optimised not only for the use with the AF2000 but also for easy interfacing with high-end detection technologies from other suppliers that may already be at use in your laboratory.

Silica-Free Centrifugal Partition Chromatography (CPC) Columns Released
Gilson have announced an extension to its PLC purifi cation system offering by introducing centrifugal partition chromatography (CPC) columns, available with a wide range of reusable, silica-free column possibilities.
CPC columns coupled with a PLC Purifi cation System offer improved yields and better cost effi ciencies over fl ash chromatography and preparative HPLC techniques. The easily scalable systems are ideal for natural compound purifi cation, natural extract fractionation, and general molecule purifi cations for cosmetics, food supplements, and pharmaceuticals.
Using Gilson’s CPC technology in the natural product purifi cation process results in greater than 95% recoveries with 99% purity. The CPC columns are ideal for labs that are going green. They create less waste by being reusable, and provide cost savings by eliminating expensive column replacement and silica recycling. The technology also uses fi ve times less solvent than preparative HPLC and fl ash chromatography.
The silica-free CPC columns offer large injection capacity, from milligrams to multi-kilograms depending on the size of CPC column. Gilson purifi cation systems provide preparative- to industrial-scale purifi cation of highly complex samples without sample pretreatment.
To streamline workfl ows, this Gilson purifi cation system can be completely controlled through Gilson Glider software. As chromatographic columns, the Gilson CPC can connect to any preparative liquid chromatography system.
Gilson offers complete purifi cation solutions. Now with the combination of Gilson’s CPC column with the PLC Purifi cation Systems, researchers have the fl exibility to easily use either CPC, fl ash, or preparative HPLC columns as needed.
