Laboratory Products 43 Improved Conformance Testing of Gravimetric Gas Sorption Analysers
Hiden Isochema has introduced a NIST traceable method for assessing the combined pressure, uptake and temperature measurements of gravimetric sorption systems. An in situ densitometry procedure is used to simultaneously determine mass and volume of an externally calibrated float. The volume is measured within 0.001 cc across the analyser pressure range and is equivalent to a 1 µg (microgram) air displacement at standard temperature and pressure.
A specific tolerance is calculated from the test conditions and the sensor specifications of a given analyser to yield a clear pass / fail condition for certification. The method also enables both the absolute combined accuracy and linearity to be quantified in specific operating conditions since it can be applied to any species including non-ideal gases such as carbon dioxide and methane.
This rigorous conformance testing is applied as standard to all new IGA and XEMIS series analysers and also during routine instrument servicing. A test kit and accompanying software protocol is also offered for user conformance testing to suit the requirements of their site quality management system.
Hiden Isochema’s Managing Director, Dr Mike Benham, said: “The recent improvements in our conformance testing methods add further to the confidence. Hiden Isochema, and in turn our customers, have in the accuracy of data measured using our gravimetric sorption analysers. This unprecedented tolerance level is a further demonstration of Hiden Isochema’s commitment to the quality of both our instruments, and our testing protocols.”

New Molecular Diagnostics Website Unveiled
New Quick Couplings for Safe Separation
THERMOREGULATION INTELLIGENT
Beckman Coulter Diagnostics has launched its new website specifically for molecular diagnostics. The new site
beckmancoulter.com/moleculardiagnostics has been designed not only to showcase the company’s DxN VERIS Molecular Diagnostics System but also to provide quick and easy access to scientific resources and educational materials for the molecular diagnostics laboratory.
“Our aim with the new site has been to make finding information about our molecular diagnostics products, both the DxN VERIS system and its growing portfolio of assays, quick and simple,” said Jaime Menendez- Humara, Director Global Marketing for Molecular Diagnostics, “We are also dedicated to building a dynamic and evolving platform to enable easy access to new scientific and educational materials that will assist our customers and those who wish to learn more about the unique workflow and cost benefits of our molecular diagnostic products.”
“For decades, Beckman Coulter has been at the forefront of laboratory diagnostics, and through significant investment and strategic input from our parent company, the Danaher Corporation, and the expertise of our R&D scientists, we now have a unique offering in molecular diagnostics,” commented Richard Creager, Senior Vice President of Molecular Diagnostics and CSO of Beckman Coulter Diagnostics. “The DxN VERIS consolidates extraction, amplification and detection into one platform, immediately saving operator time, space and costs. When you combine this with the system’s true single-sample, random-access capability that allows multiple assays and samples to be run at the same time, workflow efficiencies lead to greater laboratory productivity, something that is being called for in laboratories worldwide,” he concluded.
The system is fully CE-marked, with assays for Human Immunodeficiency Virus (HIV-1), Hepatitis C Virus (HCV), Hepatitis B Virus (HBV) and Human Cytomegalovirus (CMV). Further menu expansion will follow with many other assays currently in development. Assays are supplied in a unique, single cartridge system so, unlike traditional batch-plate systems, there are no empty wells, reducing wastage and consumable costs. All consumables and reagents are on-board, so there is no lengthy set-up and tests can be up and running in less than 10 minutes with auto-verified results in 70 minutes.

Temperature control units are usually connected to the application (e.g. reactor) with insulated hose lines. The separation points are usually equipped with metal-sealing glands. The quick couplings available on the market are usually neither suitable for the temperature range nor for the broad range of temperature control media. High pressure drops often result in a poor performance of the overall system. Another problem is disconnecting the temperature control unit from the application – so far; the circulator always had to be emptied. Huber Kältemaschinenbau therefore developed new quick couplings that meet the special requirements for temperature control applications and safely prevent the escape of thermofluid when disconnecting.
The new quick couplings guarantee an optimum flow, low pressure loss and good heat transfer. All components are made of stainless steel and with high-quality, durable sealing compounds for safe operation. Minimum axial coupling forces required due to a bayonet locking device. Optional equipment on request, e.g. ATEX approval for Zone 2 or dust and insulation caps.
