| Research Abstract |
Specially ordered, polycapillary lens, its collimator, automatic control system, and sample holder were installed on our ultra soft X-ray spectrometer, and measured Na-K and Mg-K XANES spectra of respective aqueous NaCl and MgClz solutions at Kyushu Synchrotron Center. We could obtain clear and excellent S/N ratio spectra of 0.1 molar solutions. This tells our new spectrometer system is capable to In-situ Imaging measurement of light metal elements in biological samples. We cultivated rice under several soil conditions including Si element, and measured its Si-K XANES spectra analyzed by a DV-Xa method.
