Summary

**Summary:** This file contains a high-resolution Energy Dispersive X-ray Spectroscopy (EDS/EDX) spectrum acquired using a Bruker Nano detector on a Scanning Transmission Electron Microscope (STEM). The dataset captures X-ray emission data across 4,096 energy channels (0–~40 keV) with associated count rates (CPS), collected on May 5, 2022. **Context & Parameters:** - **Technique:** STEM-EDX (200 keV primary electron energy), likely for elemental mapping or point analysis of catalyst materials at nanoscale resolution - **Acquisition:** ~250 s real time / ~206 s live time; detector positioned at 22° take-off angle, 45° azimuth - **Detector:** Custom solid-state detector (likely SDD), 0.45 mm thickness, windowless configuration, energy resolution ~129 eV (Mn Kα), calibrated at ~10 eV/channel - **Data:** Spectrum spanning channels 0–4095 with corresponding energy values (offset: -951.4 eV) and count data, suitable for quantitative elemental identification of the sampled catalyst region
