Microautoradiography and Electron Probe Analysis
Author: U. Lüttge
Publisher: Springer Science & Business Media
ISBN: 3642874967
Category : Science
Languages : en
Pages : 245
Book Description
In biological literature, several definitions of quantitative autoradio graphy are given. The term is defined as either the determination and com parison of the density of silver grains above various structures or under varying conditions, or the determination of absolute quantities of radio activity. In both these cases, photometric measurement serves for more rapid and more exact evaluation of grain densities than would be possible by visual counting of the grains. The equipment generally used for the photometric measurement of silver grains consists of a microscope, a photocell, an electronic amplifier system and a display unit. Grains can be made accessible to photometric evaluation by various kinds of microscopic illumination: 1. Substage bright-field illumination. 2. Substage dark-field illumination. 3. Incident dark-field illumination. 4. Vertical bright-field illumination. With all these types of illumination, the relationship between the luminous flux I absorbed by the film, scattered into the objective and reflected or diffracted, and the flux 10 which is not affected by the film is used as a measure of grain density. Since these are differential measurements, the light beam I transmitted by the film is in itself a measure of grain density if the luminous flux 10 incident on the grains is kept constant. This approach has been used in a large number of measuring setups.

Biomedical Applications of Microprobe Analysis
Author: Peter Ingram
Publisher: Academic Press
ISBN: 0080524567
Category : Science
Languages : en
Pages : 573
Book Description
Biomedical Applications of Microprobe Analysis is a combination reference/laboratory manual for the use of microprobe analysis in both clinical diagnostic and research settings. Also called microchemical microscopy, microprobe analysis uses high-energy bombardment of cells and tissue, in combination with high resolution EM or confocal microscopy to provide a profile of the ion, metal, and mineral concentrations present in a sample. This allows insight into the physiology and pathophysiology of a wide variety of cells and tissues.This book describes methods for obtaining detailed information about the identity and composition of particles too small to be seen with the naked eye and describes how this information can be useful in diagnostic and biomedical research. - Up-to-date review of electron microprobe analysis - Detailed descriptions of sample preparation techniques - Recent technologies including confocal microscopy, infrared microspectroscopy, and laser raman spectroscopy - Over 100 illustrations with numerous specific applications - Contributions by world-renowned experts in the field - Brief summary of highlights precedes each chapter

Principles and Practice of X-Ray Spectrometric Analysis
Author: E.P. Bertin
Publisher: Springer Science & Business Media
ISBN: 1461344166
Category : Science
Languages : en
Pages : 1098
Book Description
Since the first edition of this book was published early in 1970, three major developments have occurred in the field of x-ray spectrochemical analysis. First, wavelength-dispersive spectrometry, in 1970 already securely established among instrumental analytical methods, has matured. Highly sophisticated, miniaturized, modular, solid-state circuitry has replaced elec tron-tube circuitry in the readout system. Computers are now widely used to program and control fully automated spectrometers and to store, process, and compute analytical concentrations directly and immediately from ac cumulated count data. Matrix effects have largely yielded to mathematical treatment. The problems associated with the ultralong-wavelength region have been largely surmounted. Indirect (association) methods have extended the applicability of x-ray spectrometry to the entire periodic table and even to certain classes of compounds. Modern commercial, computerized, auto matic, simultaneous x-ray spectrometers can index up to 60 specimens in turn into the measurement position and for each collect count data for up to 30 elements and read out the analytical results in 1--4 min-all corrected for absorption-enhancement and particle-size or surface-texture effects and wholly unattended. Sample preparation has long been the time-limiting step in x-ray spectrochemical analysis. Second, energy-dispersive spectrometry, in 1970 only beginning to assume its place among instrumental analytical methods, has undergone phenomenal development and application and, some believe, may supplant wavelength spectrometry for most applications in the foreseeable future.
