XAS/DRIFT/MS setup

At ID24-DCM a significantly improved version of XAS/DRIFT/MS setup is available to the users. For packed powder it delivers the XAS data quality equivalent to conventional in situ XAS cells (such as Microtomo cell, TPC, etc). The DRIFTS setup is currently available at both BM23 and ID24-DCM. Measurements are possible in both transmission and fluorescence modes.

Measurement time ca. 3 min/spectrum. Courtesy A. Molokova and D. Salusso (ESRF).
