Research ArticleOpen accessEvery word in the titleFabrication of X-Ray Optics for a Portable Total Reflection X-Ray Fluorescence Spectrometer Using Electrolytic in Process Dressing Grinding and Magnetorheological FinishingShinsuke Kunimura, Hiroshi Kasuga, Yosuke Hachisu, Hitoshi OhmoriProblem statement: A portable X-ray elemental analyzer (total reflection X-ray fluorescence spectrometer) has been developed since 2006 and this spectrometer made it possible to perform ultra trace elemental determination. The intensity of scattered X-rays that become background noise in a spectrum is reduced with the improvement in surface accuracy of an X-ray reflector used in the portable spectrometer and therefore … …Current Research in Nanotechnology, Vol. 1, Issue 2 · 21 Jun 2011 · 7,293 accessesView PDF Cite

Research ArticleOpen accessIn the abstractNear Infrared Spectroscopy Identification Method for Five Chemical Types of Cinnamomum camphoraBailian Tu, Yueting Zhang, Yongjie Zheng et al.To more quickly and accurately identify the five chemical types of Cinnamomum camphora, a desktop and portable near-infrared spectrometer was used to collect the near-infrared spectra of the leaves of the five chemical types of C. camphora. Combined with chemometric methods, the near-infrared spectra of different chemical types of C. camphora were discriminated and analyzed. Using a desktop near-infrared spectrometer … …American Journal of Biochemistry and Biotechnology, Vol. 21, Issue 1 · 20 Feb 2025 · 5,288 accessesView PDF Cite
