Product Information

Digested cathode powders were analyzed with the prepFAST MX+ connected to an Avio 500. This setup, powered by Xceleri software, allows for an automated standard addition method that provides more accurate results, less sample preparation, and reduced acid waste.

Nanoparticle and single cell elemental analysis by ICP-MS has become popular in recent years due technological advancements in ICP-MS, as well as increasing needs for many other advancing fields of applications (1). In the current study, an automated, micro-flow autosampler in combination with an Inductively Coupled Plasma-Mass Spectrometry (ICP-MS) is used in the elemental analysis of nanoparticles and yeast cells. The sample introduction system is designed to deliver intact single cells or cell clusters to the plasma, while the ICP-MS offers high sensitivity for elemental determination within the cell or cell cluster. The preliminary results from this current study can potentially be applied to other applications, offering an easy and efficient way for high-throughput sample analysis.

CLIN-0500 ICPMS matrix-matching solution improves detection limits up to 20x or more for important elements such as Mn, Se, and Pb while also improving accuracy. Methods were validated by analyzing proficiency testing samples from NYDOH and CTQ programs.
