Thermo Fisher Scientific Introduces Speciation Analysis Capabilities for High Resolution ICP-MS

Product news

Thermo Fisher Scientific Inc., the world leader in serving science announces the addition of a new kit for coupling Gas Chromatography (GC) to the Thermo Scientific high resolution ICP-MS ELEMENT 2 and ELEMENT XR. Designed to enable scientists to use a high resolution magnetic sector field ICP-MS as a detector for GC, the kit extends traditional ICP-MS capabilities for elemental speciation analysis of volatile compounds. This novel system is the latest offering, further expanding the unique and comprehensive capabilities of the Thermo Scientific ELEMENT 2 and ELEMENT XR which are manufactured at the company’s Mass Spectrometry Center of Excellence, based in Bremen.

In recent years there has been increasing interest in the ability to perform measurements of not just the total concentration of elements in samples, but also the relative levels of the different species of elements that are present. This is because each molecular compound or oxidation state of an element exhibits unique properties such as toxicity, reactivity or metabolic pathway in living organisms. An effective analytical approach to enable this type of speciated elemental analysis is by separation, using a chromatographic technique, and detection using the highly sensitive element specific technique of ICP-MS. Separations for volatile species can be performed using gas chromatography (GC), whilst detection with high resolution ICP-MS offers the benefit of increased sensitivity and selectivity. The Thermo Scientific kit enables analysts working in the environmental, clinical and biological markets to detect and quantify the volatile compounds of elements such as sulfur, tin, phosphorous, mercury and bromine, at significantly lower levels than traditional techniques thanks to the solution’s high sensitivity and, in some cases, the ability to resolve interfering ions from the mass spectrum.

Thermo Fisher Scientific already offers a GC coupling kit for the Thermo Scientific XSERIES 2 quadrupole-based ICP-MS. and has used the same unique dual sample introduction for the high resolution ICP-MS. This offers simple instrument set up and internal standardization using simultaneously nebulized solutions in parallel to the GC sample gas stream. This new GC-ICP-MS interface for high-resolution ICP-MS is unique in the market.

The new Thermo Scientific coupling kit enables high resolution ICP-MS to work alongside any GC system, giving customers the ability to detect species using high resolution with their existing GC system.

Gas ChromatographyGas chromatography (GC) is an analytical technique used to separate and quantitate mixtures of small and volatile compounds. Gas chromatographs or GC systems include components such as GC columns, detectors, pumps and autosamplers. Choose from packed or capillary GC columns, flame ionization (FID), photoionization (PID) electron capture detectors and selective or non-selective detectors.

It provides detailed information about the structure, composition, and properties of compounds and is widely used across fields such as environmental monitoring, materials science, drug discovery and development, food and beverage testing, and wider chemical research. Key MS techniques include tandem mass spectrometry (MS/MS), liquid chromatography–mass spectrometry (LS-MS) and inductively coupled plasma (ICP-MS). Choosing from these wide range of techniques and technologies can be a daunting task, so keep up to date with scientific applications, performance expectations, and customer reviews here all in one place. Visit our product directory to receive quotes direct from the manufacturer. Environmental Monitoring and TestingEnvironmental monitoring and testing uses handheld portable analyzers, kits, spectrometers or chromatography systems for air, water, soil, food and other sample testing. Useful features of analyzers such as BOD and COD include portability, easy calibration, automation and sensitivity.  Environmental test kits for pH, water, moisture, etc, should be accurate, sensitive, reliable, fast and easy to use.GC-MS GC-MS (gas chromatography-mass spectrometry) instruments and equipment are used to separate, quantify and identify mixtures of small and volatile compounds, such as polycyclic aromatics, fatty acids and alcohols. Often used in drug detection, forensic investigation and environmental analysis for pesticides and contaminants, GC-MS is a powerful addition to your lab’s analytical capabilities. GC-MS/MS instruments equipped with a qTOF or triple quadrupole analyzers can give greater sensitivity and resolution to your analysis.
