ICP-OES Analysis for Humic Substance

Russian Agricultural Sciences, 2023
The possibilities of optical emission spectrometry with inductively coupled plasma (OES-ICP analysis) (in radial plasma observation) of humic preparations (HP) are evaluated, the proposed technique allows quantifying up to 24 elements (As, Al, B, Ba, Ca, Cd, Co, Cr, Cu, Fe, K, Mg, Mn, Mo, Na, Ni, P, Pb, Si, S, Sr, Ti, V and Zn).

Comparisons between LIBS and ICP/OES

Analytical and Bioanalytical Chemistry, 2006
In the framework of the development of new techniques, the ability of laser-induced breakdown spectroscopy (LIBS) to analyse remotely complex aqueous solutions was investigated. The jet configuration with a collimated gas stream was chosen because it appeared to be the most promising method for the LIBS probe, particularly in terms of sensitivity and ...

Understanding the Fundamental Components of Sample Introduction for ICP-OES and ICP-MS

Spectroscopy, 2022
Analytical techniques based on inductively coupled plasma (ICP) are commonly used for analyzing the elemental composition of a sample and are widely applied in analytical testing laboratories. Particularly for larger laboratories, analysis time and throughput are essential performance indicators, which can be severely impacted if sample analysis needs ...

Quantification of Si in Silicone Oils by ICP-OES

Silicon, 2014
A new simple and low cost method of quantification of trace amounts of silicon (Si) in silicone oils has been developed by combining the silicone emulsion and inductively coupled plasma optical emission spectroscopy (ICP-OES) analysis. Silicone oils that contained phenyl groups in the viscosity range from 20 to 1000 mPa.s formed stable oil in water ...

The concentration and probabilistic health risk assessment of trace metals in three type of sesame seeds using ICP- OES in Iran

International Journal of Environmental Analytical Chemistry, 2020
The most trace metals (essential and toxic metals) in very low concentrations are needed for living organisms, especially humans, but if they exceed the recommended limit, they can lead to toxicity in humans.

Multisignal calibration in spark- and ICP-OES

Fresenius' Journal of Analytical Chemistry, 1994
The advantages of multivariate calibration by using more than one selective emission line for one analyte are described in comparison with univariate calibration. Principle component regression (PCR) and partial least squares regression (PLS) are compared with classical univariate linear regression of single lines.
