The Determination of Toxic, Essential, and Nutritional Elements in Food Matrices Using the NexION 300/350 ICP-MS

22 Sept 2014

This application note describes a method for the analysis of various food substances using the NexION® 300X ICP-MS, focusing on toxic and typical essential and macro elements in a group of NIST® (Gaithersburg, MD) standard reference materials (SRMs).

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.
