Inductively coupled plasma component parts

The focus of most standardized grease testing has been upon performance and appearance, rather than determining the concentration of chemical components. In part, this is likely due to the relative volume of grease demand when compared to other lubricants. But the primary reason may be that grease is a rather difficult matrix with which to work fi om the perspective of the analytical laboratory. Lubricating oil may be diluted in a solvent and introduced directly into an Inductively Coupled Plasma Atomic Emission Spectrometer (ICP-AES) for rapid elemental measurements. Grease, on the other hand, does not dissolve in any common laboratory solvent that is compatible with ICP-AES. 

Part III provides several conventional, environmental evaluation processes for surface finishing. In chapter The Necessity and Meaning , we describe the necessity and meaning of enviromnental evaluation for surface finishing. Also we discuss evaluation processes that have already been used. In chapter Frequently Used Evaluations for Effluents , the Inductively Coupled Plasma Atomic Emission Spectrometer (ICP-AES) and the Inductively Coupled Plasma Mass Spectrometer (ICP-MS) are mainly described and discussed as conventional, but powerful analytical tools. In chapter Frequently Used Evaluations for Aerial and Solid Pollution , the conventional analyses for aerial and solid pollution are presented. These types of pollution have caused very serious problems. Therefore, various countermeasures have been devised for them. And even nowadays, new problems such as air pollutants called particulate matter are emerging. These air pollutants include solid particles and liquid droplets that come in various sizes. The small particles that are 2.5 pm or less are called PM2.5. In this chapter, we also focus oti gas chromatography/ion chromatography from the fundamental viewpoint. In chapter Dissolution Assay , the dissolution assay process is described. This type of analysis is used to measure the dissolution amounts and characteristics for many kinds of metal components of materials.

Morita and Hattori 7] used an inductive excitation from outside the reactor chamber made of silica or glass. However, it has been shown by Vossen [98] that even in this case the coupling of the rf power into the dischaige is captive and therefore sputteretching of the inner part of the silica wall, imdemeath the turn of the coil, can happen and, correqx>ndin y, impurities mi t be incorporated into the growing deposit (Holland et al. [99]). The substrate may be placed inside or outside the plasma zone as it is shown in Fig. 13c, and the metal is evaporated into the stream of the excited species. Both components travel to the substrate where they combine into a composite film (Hori et al. [100]). In a further development, Itoh et al. [101] used a tem vdiere the discharge is excited between mesh electrodes (Fig. 13 d). Basically it is a variation of the system from Fig. 13 b. A similar system has also been used by Janca and Pavelka [93]. Other workers used instead of mesh electrodes a coil of several turns for the if discharge excitation (Asano [102] and Suzuki et al. [103]).
