The instrument is employed in catalysis research. The key component is a von Hamos full cylinder optic with Highly Annealed Pyrolytic Graphite (HAPG) as a dispersive element. With this very efficient optic, the spectrometer subtends an effective solid angle of detection of around 1 msr, allowing for the analysis of dilute samples. The resolving power of the spectrometer is approximately E\/\u0394E = 4000, with an energy range of \u223c2.3 keV\u201310 keV. The instrument and its characteristics are described herein. Further, a comparison with a prototype spectrometer, based on the same principle, shows the substantial improvement in the spectral resolution and energy range for the present setup. The paper concludes with a discussion of sample handling. A compilation of HAPG fundamentals and related publications are given in a brief Appendix.<\/jats:p>","DOI":"10.1063\/1.5035171","type":"journal-article","created":{"date-parts":[[2018,11,15]],"date-time":"2018-11-15T10:51:58Z","timestamp":1542279118000},"update-policy":"https:\/\/doi.org\/10.1063\/aip-crossmark-policy-page","source":"Crossref","is-referenced-by-count":49,"title":["A laboratory spectrometer for high throughput X-ray emission spectroscopy in catalysis research"],"prefix":"10.1063","volume":"89","author":[{"given":"Wolfgang","family":"Malzer","sequence":"first","affiliation":[{"name":"Institute for Optic and Atomic Physics, Technische Universit\u00e4t Berlin 1 , Hardenbergstr. 36, 10623 Berlin, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Daniel","family":"Gr\u00f6tzsch","sequence":"additional","affiliation":[{"name":"Institute for Optic and Atomic Physics, Technische Universit\u00e4t Berlin 1 , Hardenbergstr. 36, 10623 Berlin, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Richard","family":"Gnewkow","sequence":"additional","affiliation":[{"name":"Institute for Optic and Atomic Physics, Technische Universit\u00e4t Berlin 1 , Hardenbergstr. 36, 10623 Berlin, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Christopher","family":"Schlesiger","sequence":"additional","affiliation":[{"name":"Institute for Optic and Atomic Physics, Technische Universit\u00e4t Berlin 1 , Hardenbergstr. 36, 10623 Berlin, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Fabian","family":"Kowalewski","sequence":"additional","affiliation":[{"name":"Max Planck Institute for Chemical Energy Conversion 2 , Stiftstr. 34-36, 45470 M\u00fclheim an der Ruhr, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3650-7765","authenticated-orcid":false,"given":"Benjamin","family":"Van Kuiken","sequence":"additional","affiliation":[{"name":"Max Planck Institute for Chemical Energy Conversion 2 , Stiftstr. 34-36, 45470 M\u00fclheim an der Ruhr, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Serena","family":"DeBeer","sequence":"additional","affiliation":[{"name":"Max Planck Institute for Chemical Energy Conversion 2 , Stiftstr. 34-36, 45470 M\u00fclheim an der Ruhr, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Birgit","family":"Kanngie\u00dfer","sequence":"additional","affiliation":[{"name":"Institute for Optic and Atomic Physics, Technische Universit\u00e4t Berlin 1 , Hardenbergstr. 36, 10623 Berlin, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"317","published-online":{"date-parts":[[2018,11,15]]},"reference":[{"key":"2023070421165988400_c1a","doi-asserted-by":"publisher","first-page":"901","DOI":"10.1007\/bf01328379","volume":"33","year":"1925","journal-title":"Z.
