Owing to its fluorescence-optimized geometry, vacuum compatibility and adjustable electrode spacing, the cell is also suitable for several other synchrotron X-ray techniques.\u003cbr\u003eIn addition to XAS, the cell is compatible with X-ray Fluorescence (XRF), X-ray Emission Spectroscopy (XES), Resonant X-ray Emission Spectroscopy (RXES), High-Energy-Resolution Fluorescence-Detected X-ray Absorption Spectroscopy (HERFD-XAS) and, depending on the experimental setup, Resonant Inelastic X-ray Scattering (RIXS).\u003cbr\u003eThe cell may also be used with selected X-ray scattering and diffraction techniques, including Reflection X-ray Diffraction (Reflection XRD) and Wide-Angle X-ray Scattering (WAXS). Depending on the available beamline geometry and sample positioning capabilities, compatibility with Grazing-Incidence X-ray Diffraction (GIXRD), Grazing-Incidence Wide-Angle X-ray Scattering (GIWAXS), Grazing-Incidence Small-Angle X-ray Scattering (GISAXS) and X-ray Reflectivity (XRR) may also be achievable.\u003cbr\u003eThe cell is not intended for transmission-mode measurements, including transmission XAS, transmission XRD or transmission SAXS\/WAXS, as its geometry is specifically optimized for fluorescence detection and reflection-based experiments.\u003cbr\u003eAlthough the cell has been designed to maximize compatibility with a wide range of synchrotron X-ray techniques, the suitability for a particular experiment depends on the beamline configuration and the complete experimental setup. Before purchasing the cell, users should verify that the available incident beam geometry, detector position, spectrometer acceptance, sample environment, vacuum chamber dimensions, angular access, working distance and mechanical clearances are compatible with the cell. Certain experimental stations may impose geometric or instrumental constraints that limit or prevent the use of specific techniques, even though they are generally compatible with the cell design.\u003cbr\u003eThis cell includes complimentary beamline compatibility support. If the standard cell configuration is not fully compatible with a specific beamline or experimental setup, redox.me will evaluate the limitations and, whenever technically feasible, modify the cell or provide dedicated adapters to ensure compatibility. This service is provided free of charge and is intended to simplify integration with different synchrotron beamlines while minimizing the need for custom engineering by the user. \u003cbr\u003eFor troubleshooting instruction see the \u003ca href=\"https:\/\/redox.me\/blogs\/good-measurement-practices\/troubleshooting-electrochemical-cell\"\u003eredox.me blog post\u003c\/a\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eSpecification\u003cbr\u003e\u003c\/strong\u003e\u003cspan\u003e\u003cspan\u003eWE type: flat plate, thin film substrate, etched substrate or microfabricated chip\u003cbr\u003erecommended WE dimensions: 10 mm × 10 mm\u003cbr\u003eminimum WE dimensions: 8 mm × 8 mm\u003cbr\u003emaximum WE dimensions: 13 mm × 13 mm\u003cbr\u003eWE included: no\u003cbr\u003enumber of WE contacts: 2\u003cbr\u003eWE contact arrangement: front-side and rear-side contacts\u003cbr\u003eWE contact material: tantalum\u003cbr\u003eWE assembly: screw-free\u003cbr\u003eCE material: glassy carbon rod\u003cbr\u003eCE diameter: 5 mm\u003cbr\u003eRE: micro leak-free Ag\/AgCl\u003cbr\u003eWE-to-CE distance: continuously adjustable from 0 to 4 mm\u003cbr\u003emicrometer scale resolution: 20 µm\u003cbr\u003eelectrolyte operation: static or flow\u003cbr\u003emaximum fluorescence\/scattering collection angle: 76° from WE surface normal\u003cbr\u003eX-ray detection mode: fluorescence and reflection geometries\u003cbr\u003etransmission-mode compatibility: no\u003cbr\u003evacuum compatibility: yes\u003cbr\u003etubing OD: 1\/16 inch\u003c\/span\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eIntrastat data\u003c\/strong\u003e\u003cbr\u003eHS Code: 90275000 \u003cbr\u003eCountry of Origin: Sweden \u003cbr\u003eNET weight: 200g\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eProduct includes\u003cbr\u003e\u003c\/strong\u003e1 x lid screw (Ti G1)\u003cbr\u003e1 x lid (Ti G1)\u003cbr\u003e2 x gasket, 0.5 mm thick FKM or FFKM\u003cbr\u003e2 x tantalum foil contact, 0.05 mm thick\u003cbr\u003e1 x cell body with fittings (PEEK)\u003cbr\u003e1 x index mark (Ti G1) with PEEK screw\u003cbr\u003e1 x CE mount (Ti G1)\u003cbr\u003e1 x Glassy Carbon counter electrode, 5 mm dia. \u003cbr\u003e1 x micrometer thimble (PEEK)\u003cbr\u003e3 x electrode contacts (PEEK, gold-plated Cu pins)\u003cbr\u003e1 x micro leak-free Ag\/AgCl\u003cbr\u003e1 x RE termination plug\u003cbr\u003e1 x set of O-rings (FKM or FFKM)\u003cbr\u003e1 x ball head\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eRelated products\u003cbr\u003e\u003c\/strong\u003e\u003ca href=\"https:\/\/redox.me\/collections\/electrochemical-cells\/products\/bec-50-ml-basic-electrochemical-cell\" title=\"Basic Electrochemical cell\" target=\"_blank\"\u003eBEC 50 mL - Basic Electrochemical Cell\u003c\/a\u003e\u003cspan\u003e\u003cbr\u003e\u003ca href=\"https:\/\/redox.me\/collections\/laboratory-instruments\/products\/peristaltic-pump-model-a-0-07-380-ml-per-min\" title=\"peristaltic pump\" target=\"_blank\"\u003ePeristaltic pump\u003c\/a\u003e\u003c\/span\u003e\u003cbr\u003e\u003c\/p\u003e","brand":"redox.me","offers":[{"title":"water-based electrolyte","offer_id":58677896118597,"sku":"C-A-OPT_XRAY-FC-A","price":5700.0,"currency_code":"EUR","in_stock":true},{"title":"organic electrolyte","offer_id":58677896511813,"sku":"C-O-OPT_XRAY-FC-A","price":6000.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0987\/1380\/files\/1_cba3a846-47aa-471f-b97a-494af98b2713.png?v=1784998558","url":"https:\/\/redox.me\/products\/operando-x-ray-ec-flow-cell-model-a","provider":"redox.me","version":"1.0","type":"link"}
