Both ICP-OES and ICP-MS are widely used for trace element analysis . Choosing between ICP-OES or ICP-MS depends on the following parameters: Join our Community, Instrument performance Characteristics of the environmental sample Regulatory requirements, ICP-MS Main advantages ICP-MS is becoming a...

Thermo Fisher Scientific is known worldwide for providing a variety of high-purity products used in analytical and environmental chemistry research. Our comprehensive offering of Specpure analytical and environmental standard solutions are well-known for their accuracy, purity, and quality.

The standard AAS instrument consists of four components: the sample introduction area, the light (radiation) source, the monochromator or polychromator, and the detector (figure 1)., Following absorption, the characteristic wavelengths emitted from the excitation sources, the flame or graphite...

These ICP-OES systems incorporate easy-to-use software and multi-element detection technology far superior to that of single-element AAS and multi-element microwave plasma techniques., Several optimized settings are defined as standard, making these instruments ideal for users new to the technique...

Sample preparation and introduction involve rendering a liquid or solid sample into a state that the instrument can process for elemental analysis. In the case of flame AAS, this involves atomizing the sample, which involves the creation of a fine mist dispersion.

Chemical elements constitute all of the ordinary matter in the universe. Of the 118 elements that have been identified, 94 are found naturally on Earth, having either stable or unstable isotopes. Because all matter differs in its elemental composition, it also differs in its chemical properties.

Quality control (QC) testing of pharmaceuticals must be rigorous and involves multiple techniques including GC/MS, LC/MS, and elemental analysis techniques. Impurities can take many forms, from solids to volatiles and everything in between.

The petrochemical industry widely uses Inductively Coupled Plasma-Optical Emission Spectroscopy (ICP-OES) for the analysis of trace elements during extraction and refining of crude oil, where trace elements are identified and measured in drilling mud compounds, produced waters, crude oil, and in the...

A variety of sample types can be analyzed by inductively coupled plasma optical emission spectroscopy (ICP-OES), including aqueous and organic liquid and solid samples. These have to be brought into a state that theICP-OES instrument as a whole can process for elemental analysis.

Buffers are aqueous solutions of weak acids and their conjugate bases, or weak bases and their conjugate acids. Buffers show little change in pH when small amounts of strong acids or bases are added. In a biological process, pH often plays an important role in that it can affect the internal and...

The goal of almost all ICP-MS analyses is to quantify trace elements within a sample. The output of an ICP-MS is numerical, and usually provided in counts per second. For any quantitative analysis, regardless of the technique, the instrument response is largely meaningless without reference to a...

Safe and clean drinking water is critical for health. In 1974, the Safe Drinking Water Act (SDWA) was established to protect the public health from contaminants in drinking water. Federal law requires the US EPA to set the regulatory standards for drinking water.

The high light throughput optics combined with the charge injection device detector, the CID821, ensure the shortest possible analysis times. When using the iFR analysis mode, the complete spectrum is captured in one measurement, making the analysis time even shorter.
