TL;DR: In this paper, the combined use of tetramethylammonium hydroxide (TMAH) and ethylenediaminetetraacetic acid (EDTA) was used for leaching inorganic constituents from botanical samples for their determination by inductively coupled plasma atomic emission spectrometry (ICP-AES).
Journal ArticleDOI
Determination of major and minor elements in silicates by inductively coupled plasma emission spectrometry
TL;DR: In this article, a simple method for the determination of major and minor elements in silicates is reported, where a sample is treated with hydrochloric and hydrofluoric acids in a small sealed Teflon vessel.
Journal ArticleDOI
Determination of minor and trace elements in silicate rocks by inductively-coupled plasma emission spectrometry
TL;DR: In this article, a sealed teflon vessel is used to extract strontium, vanadium, and zirconium from standard silicate materials, including barium, cobalt, chromium, copper, lithium, nickel, and scandium.
Journal ArticleDOI
Determination of metals in small samples by atomic absorption and emission spectrometry with discrete nebulization
TL;DR: In this article, eight elements in NBS-SRM 1577 bovine liver and other biological standards are determined by flame atomic absorption (Ca, Cu, Fe, Mg, Mn and Zn) and emission (K and Na) spectrometry.
Journal ArticleDOI
Decomposition of bovine liver in a sealed teflon vessel for determination of metals by atomic absorption spectrometry
TL;DR: The teflon-lined bomb described in this paper is suitable for acid digestion of biological materials and total decomposition time with nitric and perchloric acids is 6 h. Blanks are low and results agree well with certified values.
