Colorado School of Mines Uses a NexION 300Q ICP-MS to Obtain a Better Understanding of the Environmental Impact of Engineered Nanomaterials

PerkinElmer
9 Oct 2012

This case study presents Dr. Ranville of the Colorado School of Mines research in the area of nanoparticle sensitivity and specificity involving the use of ICP mass spectrometry (ICP-MS). Because of its trace element capability, and extremely low detection limits, the technique is ideally suited to the characterization of ENPs, containing elements such as Ag, Au, Ti and Fe, which have been integrated into larger products such as consumer goods, foods, pesticides, pharmaceuticals, and personal care products. The ubiquitous use of goods containing these nanomaterials will inevitably lead to environmental releases, which may be studied and quantified using state-of-the-art ICP-MS technology, such as PerkinElmer’s NexION® 300Q system, which was acquired recently.

NexION 350 ICP-MS Spectrometers

PerkinElmer

When your instrument is more efficient and productive, so too are your scientists and your lab. And nothing puts the flow in your workflow better than the NexION® 350 ICP-MS. With a data acquisition speed 10 times faster than any other ICP-MS on the market, the new NexION 350 ICP-MS opens up a whole new world of efficiency and opportunity, allowing you to measure more in less time, and accurately characterize nanoparticles. In addition to the exceptional application flexibility afforded by its speed, the instrument also delivers superior uptime and productivity through a variety of unique features engineered to enhance signal stability: Triple Cone Interface produces the industry’s most tightly focused ion beam and prevents sample deposition on internal components. Quadrupole Ion Deflector turns positively charged ions 90° into the Universal Cell and filters off neutrals. Analyzing Quadrupole made of a unique steel alloy for negligible thermal expansion for unparalleled stability. No extraction lenses to clean for minimized maintenance.

Mass SpectrometryMass spectrometry (MS) is a powerful analytical technique used to identify and quantify molecules based on the mass-to-charge ratio of gas-phase ions. 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.

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.ENPsEngineered NanoparticlesNanomaterialsNanomaterials such as carbon nanotubes, fullerenes and nanoparticles are a group of materials that measure between 1-1000nm for a single unit. Analysis techniques include AFM, electron microscopy and super resolution microscopy.
