Determination of void/dead volume of liquid chromatographic columns containing β-cyclodextrin as the stationary phase. Part I. Existing methods for the determination of LC column dead volume—A survey of literature

Summary A brief critique on the existing methods for the determination of LC column dead volume is presented. The dispute and controversy among scientists regarding the definition of column void volume, as well as the methods for its determination are pointed out. Difficulties arising in connection with the determination of the dead volume of cyclodextrin columns are discussed; it seems that the applicability of conventional methods is questionable. The necessity for further research in this field is stressed.

Recent progress in the synthesis of inorganic nanoparticles

Nanoparticles probably constitute the largest class of nanomaterials. Nanoparticles of several inorganic materials have been prepared by employing a variety of synthetic strategies. Besides synthesizing nanoparticles, there has been considerable effort to selectively prepare nanoparticles of different shapes. In view of the great interest in inorganic nanoparticles evinced in the last few years, we have prepared this perspective on the present status of the synthesis of inorganic nanoparticles. This article includes a brief discussion of methods followed by reports on the synthesis of nanoparticles of various classes of inorganic materials such as metals, alloys, oxides chalcogenides and pnictides. A brief section on core-shell nanoparticles is also included.

Comparison of ten digestion procedures for the determination of arsenic in soils by hydride-generation atomic absorption spectrometry

Ten different digestion methods were investigated for the determination of arsenic in soils by hydride-generation atomic absorption spectrometry. These methods included a dry ashing/digestion, several acid-leaching procedures, and digestions in a pressure decomposition vessel or a Kjeldahl apparatus. A certified reference sample was analysed and the results obtained for five other soil samples were compared with the data obtained by spectrophotometry. A nitric/sulphuric acid digestion was the most suitable. A brief interference study is reported.
