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 Microsolv’s 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:

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 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.
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.

High Resolution Microflowmeter Ensures Reliability of Quantitative LC/MS
Testa Analytical Solutions eK announces the AB-40004 microflowmeter (µFlowmeter), a non-invasive device designed to provide continuous high precision measurement of low volume liquid flows.
Optimised to operate over the flow range 0.001 to 80 µL/minute, with an unmatched high resolution of 1nl/minute, the µFlowmeter is the perfect tool for precise measurement of low flow rates ensuring the reliability of quantitative HPLC/Mass Spectrometry (LC/MS) measurements.
Compact in size, and conveniently powered via a USB connection, the µFlowmeter is fully compatible with all organic and aqueous chromatography solvents. The affordably price device includes an easy-to-use PC based app which allows continuous recording and storage of the measured flow rates. The current flow rate is also displayed on the µFlowmeter’s integral high-resolution OLED Display, allowing easy control of current flow value. The software app will also report average and minimum/maximum values of the measured flow. All flow data is automatically stored in files that can be processed later using almost any commercial data analysis package.
The µFlowmeter uses a thermal flow sensor that is extremely accurate, sensitive, and high-resolution, as well as non-invasive. As the sensor does not interfere with the measurement it can operate over a wide dynamic range and has been demonstrated to be the perfect real-time flow monitoring tool for a growing range of liquid chromatography applications.

Chromatography Column Packs Support Protein Purification Workflows
Bio-Rad Laboratories, Inc has launched EconoFit Low-Pressure Prepacked Chromatography Column Packs to support resin screening experiments in the development of protein purification workflows.
Bio-Rad’s range of EconoFit Columns provides a wide selection of resins in a prepacked format, allowing customers to simply screen resins and select the optimal chemistry for different target molecules. The new packs include mixed-mode, cation, and anion exchange resin columns, as well as a pack designed for His-tag protein purification. The convenient, easy-to-use and disposable column format is fully compatible with Bio-Rad’s NGC Chromatography Systems and other commonly used chromatography systems. Columns are available in 1 ml and 5 ml sizes.
“Similar resins can give different results for different target molecules, and with Bio-Rad’s EconoFit Column Packs our customers can easily perform resin scouting to identify the one which yields the best outcome for their chromatography application,” said Ertan Ozyamak, PhD, Bio-Rad Global Product Manager for lab-scale chromatography products. “Our columns deliver run-to-run uniformity to support preparative scale purifications and/or method development for new target proteins, as well as to improve existing workflows.”
