Chromatography 9 Space Saving PEEK HPLC Tubing
Save space and maintain good chromatography when distance is required between your HPLC components and columns. FlexiTubes™ from Microsolv Technology are flexible length, coiled PEEK tubing that will expand and contract like a phone cord, saving space and allowing distance without causing band broadening since it is a pulse dampener. Also great for organising your -instrument and eliminating that cluttered look.
The FlexiTubes™ will provide a pulse-dampener effect for parabolic flow fluids, which will result in a quieter base line and reduce band broadening. Now at reduced prices and increased selection.

Cryogenic Trapping System for Gas Chromatography
GL Sciences has released an upgrade to their CryoFocus 4. Cryogenic cold trapping is a technique where part of a column is cooled down to temperatures down to -150°C. Analytes are focused at the head of the column by cooling its selected section to sub-ambient temperature. Analytes that might normally not be retained, can now be trapped. This refocussing within the cryo-trap will result in sharper peaks on your chromatogram.
Using the same technique as in the OPTIC instrument, the CryoFocus has a highly accurate and very fast heating ramp, up to 60°C/sec. The temperature range is limited to 350°C so that it can operate within the temperature limits of GC capillary columns. With a fast heating cryo-trap, better detection limit and better resolution can be seen on the detector.
The dosing of the liquid nitrogen to the trap is done using a valve. The sound made by such valve can be an intense presence in a laboratory. The latest CryoFocus update released includes a silent version of the valve, while improving control over the lower temperatures. The silent CryoFocus 4 upgrade is supplied with all new systems, but also available as an upgrade to your existing system. Another great example where GL Sciences upgrades their instruments not only to guarantee the highest quality, but to also provide the best user experience.

The helium shortage has persisted for years, while helium is an abundant element, it is a finite resource, which means the crisis will continue to worsen. While the Russian invasion of Ukraine will not directly impact helium supply, the conflict could have both short and long-term effects. Replace this gas now with generators with unique features.
To ensure reliable analytical results in GC and GC-MS, a high-quality hydrogen supply is essential. Nitrogen can also be an option for the carrier gas. Instrument manufacturers recommend them.
F-DGSi offers a complete range of gas generators. The COSMOS range provides peace of mind by combining safety and robustness for your analyses.
Three models of hydrogen generators differing by the type of drying of the H2 produced: COSMOS MF.H2 / COSMOS MB.H2 / COSMOS MD.H2.
Two models of nitrogen generators differing by the elimination of hydrocarbons: COSMOS N2 / COSMOS ZN2.
As the COSMOS range is stackable and modular, many laboratories also include a zero air generator to provide a flame make- up gas. And, for those without compressed air solutions, an air compressor is available to meet all your GC needs.
Automated Permeation Breakthrough Analysis Systems
When working with hazardous chemicals, appropriate protective clothing should be worn. These items of protective clothing should be tested to ensure they offer a suitable level of chemical protection. Testing the rate at which a chemical permeates through a material determines the level of protection it can offer. To achieve certification as ‘chemically protective’ by EN ISO 374-1, a glove must accomplish certain breakthrough times against several challenge chemicals.
Ellutia offers a complete system for the automatic analysis of permeation breakthroughs. The system comprises of a number of permeation cells. Optional automated challenge chemical introduction can further increase sample throughput and automation. Once each cell has had the challenge chemical applied on one side of the sample material and automatically samples the headspace from the other side periodically to plot the permeation breakthrough. The Cells can be operated in series or parallel depending on the test requirements. An Ellutia 200 Series GC analyses the Headspace from the cells, and the results are automatically plotted by custom software.

An F-DGSi generator offers a more cost-effective solution than traditional gas supply sources such as cylinders: Convenient - no gas changes or interruptions; Economical - low and controlled ongoing gas costs; Safe - eliminates the risk of leaks as the generator indicates its status by a colour code; Ecological - no repeated gas deliveries, energy efficiency; Maintenance - remote diagnostics via USB.
F-DGSi: a French manufacturer offering complete gas solutions for all analytical applications.
Don’t buy your gas, produce it.
