Integrated Chemical Reaction Facility (ICRF)
CSCP’s recently established Integrated Chemical Reaction Facility (ICRF) brings together Durham Chemistry Department’s unique high pressure laboratory and highly reactive/toxic gas handling laboratory facilities, together with state-of-the-art equipment and instrumentation, to create a world-class laboratory for the development and exploitation of interdisciplinary sustainable, efficient chemical reactions and energy-related research projects. An overview of the varied facilities available through the ICRF is given below.
(1) Gas Chromatography
- BRUKER SCION 456 GC with flame ionisation detector (FID) and thermal conductivity detector (TCD) - used to analyse a wide range of liquid and gas samples on an analytical scale to identify and quantify complex mixtures as well as being a valuable tool in testing compound purity.

- Agilent GC/MS (7820A GC/5977E MSD) provides low detection limits in complex mixtures. It features electron ionisation (EI) source, single gold quartz quadrupole with 1050 u mass range, and synchronous Selected Ion Monitoring (SIM)/Scan mode, which allows selective monitoring of ions of interest at high sensitivity, while simultaneously acquiring spectra within a specified mass range. Additionally, both MSD ChemStation and MassHunter software are available for data analysis.

(2) CDS Pyroprobe 5200 with a fast filament heating rate (up to 20 °C ms−1) and precise temperature control (max. temperature 1400 °C) is configured to permit pyrolysis of samples in different modes, such as with/without reactant gas and/or a catalyst, or under steam gasification conditions. Pyrolysis products are analysed online with Agilent GC/MS, which are injected via a heated transfer line (max. temperature 350 °C). Gas phase is analysed with CDS 5500 Fixed Gas Analyser.

(3) Synthesis workstation METTLER-TOLEDO Optimax 1001 can be easily operated from - 40 to 180 °C with precise and programmable temperature control. An experimental configuration can be chosen from a wide range of different size reactors (250 ml, 500 ml and 1 L) and stirrers for process scalability. ReactIR 15, a real-time, in situ mid-infrared based system designed to study reaction progression and provide specific information about reaction initiation, conversion, intermediates and endpoint, is coupled with the synthesis workstation for in situ monitoring to track concentration changes of key reactive and transient organic species to understand mechanism pathway, determine kinetics and detect major reaction events. It is ideal for real-time process optimization.

(4) Micromeritics ASAP (Accelerated Surface Area and Porosimetry System) 2020 is equipped with two independent vacuum systems - one for sample preparation and one for sample analysis. Having two separate systems, as well as separate preparation ports, allows sample preparation and sample analysis to occur concurrently. Inline cold traps are located between the vacuum pump and the manifold in both the analysis and the degas systems.

(5) Rayonet Photochemical Reactor RPR-208 completes with eight 254 nm or 300 nm U-shaped lamps. It has a 12” diameter centre opening in the top and bottom – vessels up to 12 inches in diameter can be used. The reactor can be used in vertical or horizontal position.

(7) Two fume cupboards are configured with compressed air, low pressure N2, high pressure (60 bar) N2, H2, O2, CO and ethylene (others possible) gas lines. The open door gateways facilitate wheel-in/-out equipment for performing various experiments.

(8) Dedicated facilities for fluorine reactions, and handling facilities for cobalt trifluoride, sulphur tetrafluoride, hydrogen fluoride, etc..

(9) Dedicated high pressure laboratory comprising separate control room and 4 independent blast cells allows for the safe operation of high pressure vessels up to 5 L / 300 bar. The configured gas lines include high pressure N2, ethylene, H2/CO, and H2 (others possible). This facility has available a diverse range of pressure vessels, which permit, stirring, agitation, sampling and different construction materials.
