Methods of analysis

Xem 1-20 trên 1154 kết quả Methods of analysis
  • As currently taught, the introductory course in analytical chemistry emphasizes quantitative (and sometimes qualitative) methods of analysis coupled with a heavy dose of equilibrium chemistry. Analytical chemistry, however, is more than equilibrium chemistry and a collection of analytical methods; it is an approach to solving chemical problems. Although discussing different methods is important, that discussion should not come at the expense of other equally important topics.

  • This volume is an update of the book, Soil Sampling and Methods of Analysis, first published in 1993. The aims of this second edition remain the same as those of the earlier edition—to provide a compilation of soil analytical and sampling methods that are commonly used, straightforward, and relatively easy to use. The materials and procedures for these methods are presented with sufficient detail and information, along with key references, to characterize the potential and limitation of each method....

  • Standard method of test for particle size analysis of soils describes a procedure for the quantitative determination of the distribution of particle sizes in soils. The following applies to all specified limits in this standard: For the purposes of determining conformance with these specifications, an observed value or a calculated value shall be rounded off “to the nearest unit” in the last right-hand place of figures used in expressing the limiting value, in accordance with ASTM E 29. The values stated in SI units are to be regarded as the standard.

  • Colloid and surface chemistry occupy a paradoxical position among the topics of physical chemistry. These are areas which have traditionally been considered part of physical chemistry and are currently enjoying more widespread application than ever due to their relevance to environmental and biological problems. At the same time, however, colloid and surface chemistry have virtually disappeared from physical chemistry courses. These topics are largely absent from the contemporary general chemistry course as well.

  • The accurate measurement of additives in food is essential in meeting both regulatory requirements and the need of consumers for accurate information about the products they eat. While there are established methods of analysis for many food additives, there are others that still require complete methods. Analytical Methods for Food Additives addresses the lack of established methods of analysis for 26 major additives. In each case, the authors review current research to establish the best available methods and how they should be used.

  • The procedures described in these standards are intended for the examination of waters of a wide range of quality, including water suitable for domestic or industrial supplies, surface water, ground water, cooling or circulating water, boiler water, boiler feed water, treated and untreated municipal or industrial wastewater, and saline water. The unity of the fields of water supply, receiving water quality, and wastewater treatment and disposal is recognized by presenting methods of analysis for each constituent in a single section for all types of waters.

  • Introduction: Propionic acid derivative analgesic-antipyretics ( Table 2.1) are non-steroidal and antiinflammatory drugs. As one of mechanisms of their pharmacological actions, inhibition of prostaglandin biosynthesis can be mentioned. Although fatal cases due to propionic acid derivative analgesic-antipyretics are not many in the world, the incidence of poisoning (including survived cases) by this drug group is relatively high among therapeutic drugs in Japan [1].
