BUNSEKI KAGAKU, 1999 気相分解(VPD)を組み合わせた全反射蛍光X線分析(TXRF), VPD/TXRF法によって, Siウェハー上の極微量Na及びAlの分析を行った. Na及びAlの高感度分析を行うために, W-Mα線を用いてTXRF測定を行った.従来のTXRFでは検出できなかった1011 atoms cm-2の汚染レベルの試料において,分析対象元素に帰属されるピークが明確に観測された.150mm径のウェハーに対してVPD処理を行った場合,検出下限値(LLD)は, LLD(Na)=3×1010 atoms cm-2, LLD(Al)=2×109 atoms cm-2であり,従来法と比較しておよそ2けた向上した.得られた結果を原子吸光法の結果と比較し,両者に良い一致が見られた ...

INDUSTRIAL HEALTH, 1970 A combined use of X-ray fluorescent analysis and X-ray powder diffraction analysis is proposed for collecting precise and systematical information about the fundamental characteristics of fume from very small amount. This method, completely non-destruc-tive in most cases, can analyze directly the samples collected on filter paper and is able to ...

Journal of Biological Chemistry, 1981 Fluorescence polarization of cis- and trans-parinaric acid and high angle x-ray diffraction are used to examine the physical effects of in vitro sterol depletion of LM cell plasma membranes. Measurements on lipids isolated from the normal plasma membrane show that most of the lipid is fluid between 5 and 45 degrees C.
