Gilson reinforces HPLC position at Analytica

Its initial offering is a first for Gilson, as it makes available its range of multichannel pipettes.

Gilson have made comfort and usability a priority as the pipettes feature a patented, multifunction thumbwheel that ensures a fast way to set the volume, navigate and select menu options.

The ergonomic design of the body handle addresses users' concern for Repetitive Strain Injuries while the proprietary Forceless Integrated Tip Ejection System (G-F.I.T.) provides reliable seals with low tip ejection forces.

The G-F.I.T. System is based on a special stepped design of the tip-holders as apposed to the conventional conical design.

Fitting a tip produces two small contact areas between the tip-holders and the tips. The first ridge creates a ring-shaped contact area that focuses the seal force on a very small area, and in turn, provides an efficient air-tight seal.

The second works as a guide and a stop to prevent over-insertion of the tip-holder into the tip. The G-F.I.T. System is compatible with most standard tips.

The Pipetman Concept multichannel x300 is available in 8- and 12-channel models, and covers a volume range of 20µL to 300µL.

Gilson also takes the opportunity to present the PREPFC fraction collector - its solution that includes a three-way valve providing flow rates up to 200 mL/min.

The flexible, elevating tray accommodates vessels of various sizes from 9 mL test tubes to 1-litre bottles with Gilson's new Code 90-Series racks.

Repetitive collection loops and piggybacking four PREPFC Systems is permissible with a stackable shelving system.

Trilution LC software controls all aspects of fraction collection including creating and adding custom racks, setting the FC parameters, modes and windows, as well as selecting user-defined collection patterns.

Trilution LC also offers enhanced fraction collection capabilities designed for purification and preparative LC including conditional logic FC and graphical FC optimisation.

Gilson also took the time to show off its contender for the next level in front-end LC automation by introducing the GX-281 liquid handler.

What is unique about the system is that it does not require syringe replacement to accommodate various volumes and flow rates, thus saving time and money.

With a large bed capacity that allows for a dynamic range of 5 µL to 100 mL and flow rates of 1 µL/min to 25 mL/min, the GX-281 consumes only 35" of linear bench space.

Minimal waste and carry over is accomplished with Gilson's GX-281 while accommodating generous injection volumes up to 25 mL.

All GX-281 injection modules feature a continuous flow path design for flow rates up to 200 mL/min. A flowing jet wash and accommodation up to three solvents are a few features of the new rinse station.

Gilson's GX-281 uses an integrated bar code scanner for automatic bed layout generation and pre-run bed verification. The Z-arm can accommodate vessels of 200 mm in height, while an optional 200 mL/min fraction collection valve is located on the base of the Z-drive.

Finally, Gilson make available the prepELS Detector. This universal evaporative light scattering detector (ELSD) accommodates flow rates up to 75 mL/min with simplistic, robust splitting packages, while accommodating sample masses up to 5 mg without causing the detector signal to off-scale.

The prepELS's unsurpassed capabilities on the analytical scale allow for detection of analytes down to the low-nanogram level.

With the ability to detect analytes with or without a chromophore, the detector is the ideal purification choice for obtaining the purest fractions.

Gilson's prepELS detector can be added as the primary or additional detector to any Gilson preparative or analytical solution or to any other HPLC system.

A unique filtering technology allows for the removal of baseline noise without affecting peak height or shape; while Gilson's Thermo-Split Technology optimises the detector for any mobile phase or flow rate by precisely controlling temperatures and providing a gentle vapour split.
