Elemental Analysis Principles & Methodology

Elemental analysis can be used to unravel the composition of various substances. By determining the types and quantities of elements present in a sample, it provides valuable insights across a range of fields.

From the organic analysis of carbon, hydrogen, and nitrogen in compounds to the inorganic examination of elements in solid materials, techniques such as combustion analysis, X-ray fluorescence (XRF), inductively coupled plasma optical emission spectroscopy (ICP-OES), and inductively coupled plasma mass spectrometry (ICP-MS) enable researchers to uncover the fundamental building blocks of matter.

Moreover, isotope ratio analysis offers a glimpse into the isotopic composition of elements, shedding light on origin, processes, and environmental implications.

Combustion Analysis

This technique is primarily used for organic analysis. It is commonly employed to determine the elemental composition of organic compounds, mainly carbon, hydrogen, and nitrogen. The elements are converted into their respective compounds by completely burning the sample, which can be quantitatively analyzed.

In combustion analysis, a sample is subjected to complete combustion in a controlled environment, often using excess oxygen. The combustion process converts the elements in the sample into their respective compounds, such as carbon dioxide (CO2), water (H2O), and nitrogen oxides (NOx).

By accurately measuring the quantities of combustion products generated (e.g., CO2, H2O, and NOx), the elemental composition of the sample can be determined. The stoichiometry of the combustion reactions allows for calculating the elemental ratios and, consequently, the elemental composition.

X-Ray Fluorescence (XRF) Analysis

XRF is mainly used for inorganic analysis. It is notably helpful for solid samples, such as metals, minerals, and geological specimens. XRF detects characteristic X-rays emitted by the atoms in the sample when irradiated with X-rays. It provides information about the sample’s elemental composition, including both major and trace elements.

XRF involves irradiating a solid sample with high-energy X-rays. When the X-rays interact with the atoms in the sample, inner-shell electrons are excited and emit characteristic fluorescent X-rays as they return to their original energy state.

The emitted fluorescent X-rays carry information about the elements present in the sample. It is possible to identify the elements and quantify their concentrations by measuring their energy and intensity. XRF analysis can be calibrated using known standards for accurate elemental quantification.

Inductively Coupled Plasma Optical Emission Spectroscopy (ICP-OES) Analysis

ICP-OES is primarily used for inorganic analysis. It is well-suited for determining various elements in various sample types, such as liquids, solids, and even gasses. It is extensively employed in environmental analysis, metallurgy, and pharmaceutical research.

In ICP-OES, a sample is typically converted into an aerosol and introduced into a high-temperature plasma (generated by an inductively coupled plasma source). The plasma ionizes the sample, leading to the excitation of atoms and ions.

As the excited species return to their ground state, they emit light at characteristic wavelengths. The emitted light is dispersed and detected using an optical spectrometer. The elemental composition and concentrations in the sample can be determined by analyzing the intensities of these emitted wavelengths. Calibration with standards is employed for accurate quantification.

Inductively Coupled Plasma Mass Spectrometry (ICP-MS) Analysis

ICP-MS is versatile and used for organic and inorganic analysis, depending on the specific application. It can detect and quantify elements at trace levels and is often employed in environmental monitoring, geological studies, and bioanalysis. In addition to elemental composition, ICP-MS can also provide information about isotopic ratios of elements.

ICP-MS combines an inductively coupled plasma source with a mass spectrometer. Like ICP-OES, the sample is converted into an aerosol and introduced into the high-temperature plasma. However, instead of detecting emitted light, ICP-MS measures the mass-to-charge ratios of ions generated from the sample.

The ions generated in the plasma are extracted and focused into the mass spectrometer, where they are separated based on their mass-to-charge ratios. The elemental composition of the sample can be determined by detecting and measuring the ion currents at different mass-to-charge ratios. Isotope ratio analysis can also be performed by measuring the relative abundances of isotopes of specific elements.

Atomic Absorption Spectroscopy (AAS)

AAS is used for the quantitative determination of various elements in a sample. It is based on the principle of light absorption by the atoms of specific elements at characteristic wavelengths, enabling the measurement of metals, metalloids, and nonmetals in a wide range of samples, including liquids, solids, and gases.

In AAS, a sample containing the element of interest is atomized and introduced into a flame or heated graphite furnace. A hollow cathode lamp emits light at a specific wavelength corresponding to the absorption line of the element being analyzed.

As the light passes through the atomized sample, the atoms of the target element absorb light at their characteristic wavelengths, decreasing the intensity of the transmitted light. The degree of absorption is directly proportional to the concentration of the element in the sample.

AAS is beneficial for the analysis of elements in trace or ultra-trace amounts. It is highly sensitive and offers excellent selectivity, allowing for detecting and quantifying elements at very low concentrations.

While AAS is a valuable technique for elemental analysis, it has limitations. It is typically single-element specific, meaning that only one element can be analyzed at a time. Additionally, AAS requires a calibration curve using standard solutions to accurately quantify the element's concentration in the sample. Despite these limitations, atomic absorption spectroscopy remains a widely utilized and valuable tool for elemental analysis.

Isotope Ratio Analysis

Isotope ratio analysis is a specialized application of elemental analysis that focuses on the relative abundance of isotopes in a sample. Isotopes are variants of an element that have the same number of protons but different numbers of neutrons in the atomic nucleus.

The technique involves measuring the ratios of different isotopes of an element, such as carbon-13 to carbon-12 or oxygen-18 to oxygen-16. Isotope ratio analysis differs from combustion analysis and other elemental analysis techniques in its focus on the relative abundance of isotopes rather than the absolute elemental composition.

Isotope ratios can provide valuable information about a sample's origin, processes, and characteristics. Factors like fractionation, natural variations, and human activities can influence the relative abundance of isotopes. Scientists can draw conclusions about the sample’s history, environmental conditions, and authenticity by comparing the measured isotope ratios to known standards or reference materials.

The methodology of isotope ratio analysis varies depending on the elements and isotopes being analyzed.
