PEEK HPLC Column Hardware Get bio-inert, metal free HPLC columns with MicroSolv’s expanded line of PEEK column hardware. Extruded from Victrex®
PEEK this hardware the highest
quality on the market. Graphite is added (20%) to the formulation to achieve a black surface with a sheen and no other chemical or physical treatment is done leaving these columns more biocompatible.
PEEK or titanium frits of 2 µm porosity are available. The inner bore of the columns are not treated in any way and the mirror like surface is achieved through our proprietary extrusion method.
Available column packing equipment includes: packing adapters, seals, slurry reservoirs, frits & end fittings for packing stations. Now at reduced prices. More information online:

Advanced Solution for Independent Digital Maintenance and Qualification of Chromatographic Systems
Regular maintenance of chromatographic systems is intended to ensure that the instruments operate at optimum efficiency and that the separation of substances meets the highest standards. However, the maintenance of chromatographs means a high financial outlay for many labs, as it is usually carried out by the equipment manufacturers. In addition to scheduling agreements, a lot of documents and data have to be exchanged between the user and manufacturer sides – resulting in confusing paperwork and organisational efforts.
In order to make maintenance more cost- and time-efficient, AnaTox GmbH & Co KG has added a new feature to its proven AIQ Tool. The qualification software now also allows a standardised maintenance procedure for all system components, which brings significant cost advantages for equipment maintenance. The software automatically recognises the components of the system and lists the corresponding maintenance steps and associated tests. The guided process subsequently reduces downtimes to a minimum. The condition before and after maintenance is clearly documented and digitally stored. With the AIQ Tool, laboratories see themselves in a position to maintain and qualify their chromatographic environment independently and vendor-independently via a single software.
An additional advantage of the tool is the reading of the chromatograph wear counters. This data helps customers track how often the equipment has been used and how heavily certain components have been stressed. Likewise, the implemented tests can also be used individually for fault diagnosis. In this way, it is possible to order and stock spare parts in a timely manner and at a lower cost, so that replacement can be carried out quickly without having to wait a long time for a technician.

A Helium Alternative for GC
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 those without compressed air solutions, an air compressor is available to meet all your GC needs.
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.

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.
