摘要:
The importance of the noble gases in science and technology cannot be emphasized too much. It is said that man would never have gotten to the moon without helium. Perhaps that is an overstatement, but the noble gases are becoming a more vital part of our society as time passes. With the advent of modern analytical instrumentation, analyses of noble gases have become highly precise and rapid. Techniques and methods have been developed for most analytical requirements in science and industry. Pioneering work continues to be done in those areas associated with low level radioactive noble gases formed in nature and fission product noble gas, both stable and radioactive. With the current emphasis on ecology, environmental protection, and nuclear power, significant further advancements can be anticipated in the detection and identification of trace radioactive noble gas species and in the measurement of their properties, activities, and concentrations.

摘要:
The Kjeldahl method remains the method which will be used for the analysis of most samples of biological origin, the advantage being the “wet ashing” technique. The advantages of automation are apparent when applied either in whole or to part of the analytical process, and analytical performance is satisfactory.

摘要:
Although conventional flame emission and atomic absorption continue to serve as reliable and convenient methods of analysis at low concentrations, considerable research efforts, notably the development of non-flame atomizers, have extended atomic spectrometry into the range of trace and ultratrace analysis. Relatively few other analytical techniques are useful at concentration levels of 1 ppb or less, and none is as inexpensive, rapid, and readily available to most laboratories as atomic spectrometry.
