“…Calibration was performed by using thin-layer standard specimens prepared with activated carbon (Iwatsuki et al, 1997). The calibration technique has been checked in our previous works, by comparing the XRF method with instrumental neutron activation analysis (Iwatsuki et al, 1997;Kyotani and Iwatsuki, 1998). The advantage of the present method is freedom from matrix correction.…”

The unique characteristics of atmospheric aerosol in the northern foot of Mt. Fuji, central Japan were first clarified. The Mt. Fuji (an altitute of 3776 m) is the largest basaltic stratovolcano in the quaternary period in Japan. The aerosol measurements were carried out at an altitute of 1100 m from June 2000 to April 2001. Ambient aerosol in the predominant area of a typical volcanic rock like basalt was referred to as a basaltic aerosol in this study. Fifteen elements (Na, Mg, Al, Si, K, Ca, Ti, V, Cr, Mn, Fe, Cu, Zn, Ba, Pb) of major to trace in the aerosol samples were determined by X-ray fluorescence spectrometry. Total mass concentration (<10 µm) of the basaltic aerosol showed the higher values in summer and spring rather than autumn to winter, and the seasonal variation pattern differed widely from that of general urban aerosol. The behavior of the basaltic aerosol was mainly controlled by mineral particles throughout the year, so that a typical anthropogenic-derived element like Pb was very rarely detected. Even V, Cr and Zn which have been generally considered to be typical anthropogenic-derived elements, showed crustal-like behaviors. A concentration ratio of Si/Al showed markedly a uniqueness of the basaltic aerosol. From a comparison with atmospheric aerosol Si/Al ratio in granitic region being an exact opposite geology, a correlation plot of Si/Al ratio against Si concentration was made. It showed a big regional difference available for source identification of atmospheric soil particles. The chemical and geological characteristics of the basaltic aerosol are very useful for the novel characterization of atmospheric soil particles.

“…For ED XRF, the most widely used method is sam ple (and standards) preparation in the shape of tablets [166]. In XRF of thin layers a small weighted portion of the powder of the emitter is distributed as a uniform layer on a polyethylene film [167,168], sticky tape, thin film tablets [168,169] are pressed or the material is retained on a quartz deflector or membranes after acidic decomposition [170].…”

The aim of this study was to investigate the physical properties of the seed coat of Tingui (Magoniapubescens) in order to evaluate the performance of this polysaccharide as an excipient for seedpelleting. The analysis was emphasized to the flow properties including particle size, particle sizedistribution, density and moisture content of the substance. The results were compared tocommercial excipients including Microcrystalline cellulose (MCC PH 101 and SMCC), Hydroxypropyl methylcellulose (HPMC E50), Polyvinil pirrolidone (PVP K29/32), lactose andcorn starch. The data showed that Tingui was found to have bulk and tap density close to HPMCand corn starch. Particle size and its distribution were fit to HPMC and PVP; however, Tingui hadmoisture content quite close to SMCC and HPMC. In general, Tingui exhibited the free-flowproperties comparable to HPMC and PVP. Energy dispersive X-ray fluorescence analysis confirmedthat the seed coat of Tingui contains elements (K, Ca, Si and Fe) composition.
