Inductively Coupled Plasma Emission Spectrometry and Inductively Coupled Plasma-Mass Spectrometry

Abstract

The application of inductively coupled plasma-atomic emission spectroscopy (ICP-AES) to the analysis of soil and biological materials was reviewed in 1982 for this book series (Soltanpour et aI., 1982). Over the last 14 yr many studies in soil science have incorporated data obtained on ICP-AES instrumentation, and many advances in the ICP-AES field have been made. In addition, inductively coupled plasma-mass spectrometry (ICP-MS) has become commercially available. The purpose of this chapter is to review basic ICP principles; highlight some of the applications of ICP-AES in the study of soils; and present an overview of some of the instrumental features, capabilities, and limitations of the ICP-MS for application to soil science work. Relatively new developments in ICP-AES include: suspension nebulization analysis of clays (Laird et aI., 1991); interfacing ICP spectrometers with flow injection analyzers for automatic dilution, calibration, separation, concentration, standard additions and many other operations (Greenfield, 1983; LaFemiere et aI., 1985); interfacing ICP-AES with liquid chromatographs for concentration and speciation of elements (Roychowdhury & Koropchack, 1990); high salt neulizers to prevent clogging of nebulizers (Legere & Burgener, 1985); successful use of concentration and elimination or reduction of spectral interference techniques such as chelation/solvent extraction (Huang & Wai, 1986;

Linking sorghum nutrition and production with arbuscular mycorrhizal fungi and alternative soil amendments

“…Soil NO 3 -N and NH 4 -N were extracted with 1 M KCl solution and quantified using a Lachat Quickchem 8000 Flow Injection Autoanalyzer (LACHAT, 1994;Kachurina et al, 2000). Plant-available P and K were extracted using Mehlich 3 solution (Mehlich, 1984) and quantified by a Spectro Blue inductively coupled plasma (ICP) spectrometer (Soltanpour et al, 1996;Pittman et al, 2005). Soil organic C was determined using a LECO Truspec dry combustion C analyzer (Nelson and Sommers, 1996).…”

Growing Legumes in Orchard Alleys as an Internal Nitrogen Source

“…Leaves were washed twice in deionized water, dried at 45°C, and ground and analyzed with the same procedures as for the legume biomass. In addition, a complete mineral analysis of leaf samples was done in 2010 by Soiltest Farm Consultants (Moses Lake, WA) using dry combustion for N analysis and inductively coupled plasma emission spectrometry (Soltanpour et al, 1996) for all other elements.…”

Meta‐Analyses of Biosolids Effect in Dryland Wheat Agroecosystems

“…At site C, we harvested wheat grain every year from 2001 to 2013, except in 2006, when we experienced drought conditions and subsequent crop failure. We used a concentrated HNO 3 digestion of ground grain samples and analyzed the digestate with an inductively coupled plasma-atomic emission spectrophotometer (Soltanpour et al, 1996) to determine P, Zn, Cu, Fe, and Ni concentrations.…”

“…All samples were air dried, ground, and passed through a 2-mm sieve. We used ABDTPA extractions followed by inductively coupled plasma-atomic emission spectrophotometer (Soltanpour et al, 1996) to determine plant availability of P, Zn, Cu, Fe, and Ni (Barbarick et al, 1997).…”
