Quantitative Analysis of Cement by EDX-8000
High accuracy quality control analysis of cement is typically conducted using a wavelength dispersive X-ray fluorescence
spectrometer. EDX instruments have become capable in recent years of analysis accuracy comparable to that of low-output
wavelength dispersive type instruments. Not only do they offer such conveniences as the ability to analyze powders as they
are, their range of applicability has greatly widened to include the analysis of such substances as cement. Here, we introduce
the analysis accuracy obtained with pressure-formed cement standard powder samples using the new model EDX-8000.

Mechanical Strength Evaluation of Functional Film Used in Smartphones
Plastic film is formed into thin film using techniques such as extrusion and stretch molding of the polymer film. A wide variety
of products having special character ist ics, such as water retentivity, light reflectivity, and selective permeability for specific
substances, can be found all around us as industrial products, construction materials, as well as everyday necessities.

GC/MS Quantitative Analysis of Allergens in Cosmetics Using OPTIC-4
Because an estimated 1 to 2 percent of the population has allergies, in 2003 the EU began regulating the use of perfumes
and flavor materials that can cause allergic reactions. These substances are restricted to 0.01 % for cosmetic products that
are rinsed away (such as shampoo) and 0.001 % for products that are left applied (such as hand creams). Due to these
regulations, manufacturers now must quantitatively analyze the concentration of such allergens.

Development of Spheroid Energy Analyzers for Elemental and Chemical Analysis of Surfaces
The spheroid energy analyzers (SEA) are a new class of charged particle energy analyzers that are characterized with very high
energy resolution and transmission. The design of the first prototype analyzer is described. A novel geometrical framework is
presented, that describes SEA analyzers in general terms within which the well known types of analyzers CMA and CHA
appear to be only particular examples. A very high order of focusing of these analyzers is presented via simulation that
indicates the existence of 13th order focusing in one of our models. Experimental results are presented showing relative
energy resolution of 0.05ˋ of the pass energy at a transmission of 21ˋ out of a 2К steradian.

X-ray Fluorescence Analysis of Lead in Tin Plating Using Theoretical Intensity of Scattered X-rays
- Analysis of RoHS Regulated Elements by Energy Dispersive X-ray Fluorescence Spectrometer (EDX) -
RoHS regulated elements, such as cadmium and lead, are analyzed by energy dispersive X-ray fluorescence spectrometer
(EDX). However, the quantitative values obtained by this method are affected by the thickness when the sample is a thin film,
such as plating. Therefore, we measured the film thickness in an attempt to correct the quantitative values.

Development of Transparent Encapsulation Films for OLEDs Using Surface Wave Plasma CVD System
We have succeeded in developing a highly transparent, water impermeable SiNx encapsulation films for organic light-emitting
displays using a surface-wave-plasma enhanced chemical vapor deposition (SWP-CVD) system. A highly reliable barrier
performance (no deterioration for more than five years under the room temperature) was realized with above SiNx film as an
encapsulation of OLEDs.
