Proposed Instrumentation

Instrumentation presented below is based on a number of scientifically (1989) interesting areas. Although a principal agreement on a high flux, microfocus and anomalous dispersion camera has been reached, neither instrument has been defined as yet in detail. [Pg.215]

The discussion will be restricted to the design goals, as related to present research interests. Questions related to heating of optical elements, response of detection systems or data aquisition systems will not be treated. [Pg.215]


Evaluation of the performance of a method or an instrument represents the largest use of CRMs. Examples are widely reported in the literature. One could even say that the development of a new method or instrument without evaluation of the performances with (a) CRM(s) is an incomplete task. Besides these research tasks, CRMs for calibration or validation are also used to assess the performance of instruments by the manufacturer himself to demonstrate the possibilities of his instrument or by the customer who wishes to evaluate the proposed instrument before purchasing it. CRMs produced by independent official or regulatory bodies to validate instrument performance or calibration sets have been under development for several years. They have in particular allowed the solution of inaccuracy problems in the biomedical sector where calibration test kits of automatic instrument manufacturers were not comparable and even led to different results between countries such arguments supported many BCR projects for... [Pg.85]

Each instrument performance characteristic that is important to the application should be identified in the procurement specification. The specification will become part of the bid package that is sent to the vendors. In the bid package also state that the vendor must provide evidence with the quotation that the proposed instrument can meet those specifications, and on installation of the instrument, the manufacturer s installer must demonstrate that the instrument installed at your location meets those specifications. [Pg.971]

The range of characteristics of planets is likely to exceed our experience with the planets and satellites in our own Solar System by far. Models of planets more massive than our Earth - rocky Super-Earths - need to consider the changing atmosphere structure, as well as the interior structure of the planet. Also, Earthlike planets orbiting stars of different spectral type might evolve differently. Modeling these influences will help to optimize the design of the proposed instruments to search for Earth-like planets. [Pg.156]

This paper is organized as follows Section n presents the basic issues about modelling of the proposed system. Section III shows the proposed instrumentation structure. Section IV presents the experimental results of the proposed structure. Section V concludes the work. [Pg.65]

The literature review shows a gap in empirical evidence about the effects of instmments which are designed to prevent opportunistic behaviour in supply networks. This chapter contributes to addressing this gap in two ways. Firstly, the instruments which are used most frequently in practice to avoid opportunistic behaviour will be identified from the empirical study. This empirical approach is necessary at this stage as it is not yet clear whether the proposed instruments are really in use in practice. Subsequent to this first objective, the second objective is to test the effect of identified instruments on the prevention and management of opporturustic behaviour. [Pg.236]

A recent design of the maximum bubble pressure instrument for measurement of dynamic surface tension allows resolution in the millisecond time frame [119, 120]. This was accomplished by increasing the system volume relative to that of the bubble and by using electric and acoustic sensors to track the bubble formation frequency. Miller and co-workers also assessed the hydrodynamic effects arising at short bubble formation times with experiments on very viscous liquids [121]. They proposed a correction procedure to improve reliability at short times. This technique is applicable to the study of surfactant and polymer adsorption from solution [101, 120]. [Pg.35]

NMR spectroscopy is always struggling for increased sensitivity and resolution, as well as more efficient use of the instrument time. To this end, numerous improvements of the simple inversion-recovery method have been proposed over the years. An early and unportant modification is the so-called fast mversion recovery... [Pg.1508]

The field of corrected microscopes has just begun with the instruments discussed above. The progress in this field is very rapid and proposals for a sub-Angstrom TEM (SATEM) or even the combination of this instrument with a corrected energy filter to fonn a sub-electronvolt/sub-Angstrom TEM (SESAM) are underway. [Pg.1644]

The experimental facts that led van t Hoff and Le Bel to propose that molecules having the same constitution could differ m the arrangement of their atoms m space concerned the physical property of optical activity Optical activity is the ability of a chiral sub stance to rotate the plane of plane polarized light and is measured using an instrument called a polarimeter (Figure 7 5)... [Pg.287]

The current and past operation should be compared so that the timing of the observed problems is estabhshed. The possible causes (hypotheses) can be compared against the measurements found on the log sheets. The number of possible causes can then be reduced. When the quantity or quahty or measurements is insufficient to further reduce the set of causes, additional measurements are required. These may require special instruments (e.g., gamma-ray scanning) not routinely usedin the plant. Alternative operating conmtions may also be required to further reduce the number of causes. As part of the problem identification, it is alwavs important to look for measurements that are inconsistent with the proposed explanation. They will be more informative than the ones justifying the hypothesized cause. Ultimately, with appropriate additional measurements, the cause can be identified. This is not an exact science and, as stated above, relies heavily upon the communication, technical, and investigative skills of analysts. [Pg.2573]

An algorithm for an assesment of chromatographic peak purity was proposed. In this study ethyl 8-methyl-4-oxo-4/7-pyrido[l, 2-u]pyrimidine-3-carboxylate was also used (97MI13). Ethyl 7-methyl-4-oxo-4//-pyrido[l,2-u]pyrimidine-3-carboxylate, among other compounds, was applied to show practical mathematical tools for the creation of several figures of merit of nth order instrumentation, namely selectivity, net analyte signal and sensitivity (96ANC1572). [Pg.196]

Mode of operation. Before use, it is obviously necessary to become familiar with the instruction manual issued with the pH meter it is proposed to employ, but the general procedure for making a pH measurement is similar for all instruments, and will follow a pattern such as that detailed below. [Pg.566]

Physical methods for endpoint detection have been suggested. Hellsten [226] proposed an instrumental turbidimetric method to determine the endpoint, which does not need indicators. Since chloroform is emulsified by the anionic surfactant, changes in the optical density can be followed by a colorimeter thus detecting the endpoint when the emulsion breaks. Another turbidimetric method based on commercially available automatic titrators has also been proposed [227],... [Pg.280]
