Connecting Hiden's QIC series gas analysers for evolved gas analysis. A technical information sheet detailing the extensive range of TGA-MS coupling devices available.

Hydrogen is considered a safe and clean alternative to fossil fuels. Hydrogen storage is currently obtained by compressing the gas at high pressure. Researchers are currently attempting to tackle safety and energy density issues by locking hydrogen into solids, packing large quantities into small volumes. However, most of the known solids (i.e. intermetallics) show very low gravimetric density, smaller than 2 wt% of H2. Lither materials (i.e. complex hydrides) can only absorb hydrogen under extreme temperature and pressure conditions.

Maleic anhydride (MA) is commercially produced from partial oxidation of n-butane by air over vanadium pyrophosphate (VPP) catalyst. There has been a huge research interest to better understand the different aspects of this industrially attractive reaction including mechanism, dynamic catalyst phase evolutions as well as the effect of redox operating conditions such as gas/solid residence time, temperature, pressure and gas composition on the reaction yield.

Hydrogen, which can be used in many fields without polluting the environment, is thought to be the cleanest fuel source of the 21th century. Therefore, low cost production, facile storage and transportation of hydrogen are important research subjects that are investigated by many universities and related commercial facilities.

Hiden Analytical have been designing and developing the highest quality quadrupole mass spectrometer based gas analysis systems for over 25 years. We have built a reputation for delivering instruments with superior sensitivity, accuracy and reproducibility together with a first class global service and applications support network. From dedicated triple filter UHV TPD quadrupoles to fully integrated catalysis microreactor and mass spectrometer systems, Hiden have developed a range of analytical mass spectrometers that address the most advanced and demanding applications.

A complete experimental system for UHV temperature programmed desorption (TPD) studies. Features: -3F PIC detector - High precision triple filter analyser with digital pulse ion counting detector for ultimate sensitivity and time resolution. - Multiport UHV chamber. -Heated sample stage (1000 °C) with integrated PID control. - Water cooled heater for minimum outgasing and fast cool down times. - Linear sample transfer mechanism and loadlock, including gate valve and viewports. - Z-drive for optimum sample/detector positioning.

The Hiden CATLAB is a bench-top microreactor and combined mass spectrometer system for rapid and reproducible catalyst characterisation and reaction studies. The microreactor and mass spectrometer are delivered as a complete system from a single manufacturer, unique to the industry, ensuring optimum analysis via seamless hardware and software integration. The modular design further allows both instruments to operate as stand-alone components so that they may be interfaced with existing laboratory equipment such as TGAs or TCDs.

The Hiden CATLAB is a catalyst characterisation system designed to make the analysis of catalysts rapid and simple. CATLAB consists of two modules : Module 1: is the Microreactor including temperature and flow control. Module 2: is the QIC-20 Quadrupole Mass Spectrometer system, which can also be used as a stand-alone instrument.

Advanced real-time gas analysers for continuous sampling of processes and atmospheres near ambient pressure, all sharing a common system concept yet each expandable with the addition of application-specific accessories.
