52 World-fi rst Hydrogen-certifi ed, Multi-gas Enabled Thermal Desorption Instruments
Specialist analytical instrument manufacturer Markes International Ltd has launched the world’s fi rst range of thermal desorption (TD) instruments that are safety-certifi ed to run on three gases: helium, nitrogen and hydrogen. All manufacturers’ TD instruments can run on helium and nitrogen, but it’s well known that the most popular, helium, is a rapidly-dwindling, non-renewable resource, becoming ever-scarcer and more expensive. To make its TD instruments more versatile for modern laboratories, Markes has developed new versions of its UNITY-xr™, ULTRA-xr™ and TD100-xr™ instruments so that all three can be used with either helium, nitrogen or hydrogen. Each instrument has been externally tested and validated so that the full thermal desorption-gas chromatography-mass spectrometry (TD-GC-MS) analytical instrumentation and workfl ow can be confi gured to work with any of the three gases.
Dr Massimo Santoro, Markes’ Group Business Development Director, said: “While our new multi-gas technology allows for all three gases, using hydrogen carrier gas offers signifi cant fi scal and productivity benefi ts.
Financially, laboratories will have much lower running costs if they replace expensive helium with readily available, inexpensive hydrogen for their TD-GC-MS analyses.
“Furthermore, in terms of productivity, laboratories will gain considerably higher sample throughput using hydrogen instead of helium in their analytical workflows.”
The UNITY-xr is an industry-leading single tube TD unit, favoured by laboratories that have low throughput requirements and may need upgrade to autosamplers like the ULTRA-xr in the future, and/or to canister, bag or on-line analysis for wide ranging sample types and applications.
The TD100-xr is an award-winning 100-tube thermal desorber that is extremely popular with high-throughput analytical laboratories needing to process large numbers of samples, unattended.
Andy Hardwick, Commercial Director of Markes parent company, Schauenburg Analytics Ltd, said: “We’re delighted that Markes’ new range of multi-gas thermal desorbers is now available.
“Markes’ sister company, SepSolve Analytical, recently launched a hydrogen-certifi ed and enabled time-of-fl ight mass spectrometer (TOF MS) called the BenchTOF2™. While Markes manufactures specialist analytical instrumentation, accessories, supplies and consumables that enhance the sensitivity and application scope of GC–MS, SepSolve provides GC×GC, TOF MS technology and analytical software.
“The companies’ combined multi-gas enabled instruments herald an era of unprecedented change for the analytical sector as it overcomes the challenge of moving away from helium. Markes’ and SepSolve’s new instruments will enable laboratories to future-proof their systems from sampling right through to end-analysis, as well as giving them signifi cant cost-savings and higher throughput.”

Improving Yield and Quality of SARS-CoV-2 Isolated Nucleic Acid
Porvair Sciences has further expanded its range of high-performance microplate products for SARS-CoV-2 nucleic acid purifi cation. The new KF deep well plate and tip comb plate combo are specifi cally designed to enhance the performance and productivity of the market-leading Thermo Scientifi c™ KingFisher™ range of nucleic acid purifi cation systems.
Krzysztof Kielmann, Microplates Product Manager at Porvair Sciences commented: “The Kingfi sher Flex and Duo Prime systems have a number of design features that make the design of the deep well and the protective tip comb plate crucial to the correct operation of the instrument. Our optimised deep well plate has small gaps that align to locating pins on the Kingfi sher instrument and the bottom profi le of the 96 wells is designed to fi t the heater block providing close contact and sample temperature control. The protective polypropylene tip comb is designed specifi cally for the 96 magnetic probes of the Kingfi sher magnetic particle processor. The magnet slides into the disposable 96 well comb dips. Our KF deep well plate together with the protective tip comb plate has been shown to signifi cantly improve the yield and quality of the isolated protein or nucleic acid when used on KingFisher systems.”
The KF range of low affi nity deep well plates and protective tip cone plate are manufactured in a cleanroom production environment
using ultra-pure polypropylene that has the lowest leachables, extractables and is free from DNase and RNase. This allows SARS-CoV-2 test samples to be purifi ed with the confi dence of no risk of contamination or interference during the magnetic particle processing used by KingFisher™ nucleic acid purifi cation systems.
