Automated Microreactor/MS System 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 (TG-MS) or Gas Chromatographs. The...

Horizontal Furnace/MS System for Catalyst Core Quantification The CATLAB-FB is a combined furnace and mass spectrometer system for the analysis of catalyst core specimens at temperatures up to 1000°C, with multi-stream gas/vapour flow control and mass spectral analysis of both feed and downstream gases. The furnace houses a horizontal quartz reactor tube with in-bed thermocouple for optimum thermal precision, a standard internal diameter of 26 mm and a uniform central hot-zone of 150 mm. The furnace is programmable from 50°C through to 1000°C at a fastest ramp rate of 20°C/ minute. The...

BASELINE SYSTEMS for Gas Analysis BASELINE SYSTEM FEATURES INCLUDE:  Sample pressure range 2 bar to 100 mbar  Continuous sampling with inlet flow rate configurable down to 1 ml/min  Low dead volume, heated inlet for fast response to vapours  Species molecular weight range to 200 amu  Fast data acquisition speeds > 500 readings/second in transient mode  Fast 300 ms sampling response EXQ - compact gas analyser for less demanding applications  Time/intensity trend monitoring of multiple species  APSI-MS soft ionisation mode for suppression of spectral fragmentation providing simplified...

Transient MS for Fast Event Gas Analysis The Hiden HPR-20 TMS Transient MS is configured for fast event analysis of gases and vapours at pressures near atmosphere. Ideal for fast gas switching experiments, the MS features the Hiden QIC quartz-lined 0.9 m sampling interface. The inlet, operating at 200°C, provides response times of less than 150 ms to changes in gas composition with a 5 decade response time in < 100 ms. The QIC inlet is coupled directly to Hiden’s Pulse Ion Counting (PIC) digital MS which is capable of measurement speeds of up to 500 data points/s over the entire 7 decade...

for Evolved Gas Analysis in TGA-MS The Hiden HPR-20 EGA gas analysis system is configured for continuous analysis of evolved gases and vapours from thermogravimetric analysers (TGA). Interface systems are available for most TGA instruments. The TGA interface includes re-entrant furnace sampling, providing close coupling to the TGA furnace region for optimized evolved gas/vapour analysis. Custom designed interfaces are available for special requirements with alternative systems being offered for applications requiring direct sampling from advanced thermogravimetric analysers operating at...

Spatially Resolved Capillary Inlet MS The Hiden Analytical spatially resolved capillary inlet MS (SpaciMS) is the first commercially available instrument of its kind. Recipient of a R&D 100 award, the SpaciMS inlet was originally conceived and developed by researchers at the Oak Ridge National Laboratory and Cummins, Inc. to study diesel catalysis1 and has been further developed for a whole range of applications. SpaciMS allows both radial and axial species determination and temperature profiles, with high spatial and temporal resolution and with negligible interference in flow or...

A System for UHV Temperature Programmed Desorption (TPD/TDS) Studies The Hiden TPD Workstation is a complete experimental system for analysis of thermal desorption products by UHV TPD/TDS. The TPD Workstation features a multiport UHV chamber with heated sample stage coupled to a high precision triple filter analyser with digital pulse ion counting detector for ultimate sensitivity and time resolution. The triple filter mass analyser is configured with a cooled shroud giving minimum outgassing with optimum sensitivity of the analyser to desorption products from the sample. A fast sample load...

for Fast Event UHV Studies Hiden’s 3F PIC Series Quadrupoles are high precision triple filter analysers with digital detectors for ultimate sensitivity and time resolution in fast event studies such as UHV TPD. 3F Series analysers are available with UHV compatible mass filter shrouds and low profile ion source for close positioning to the desorption surface. Both analogue and digital inputs are provided for synchronous acquisition start and sample temperature data display alongside mass channel data. Application specific software and external device program protocols (RS485, Modbus) enable...
