XRF in Agronomy Applications—Analysis of Plant Tissues and Fertilizers

November 01, 2019

Special Issues

New excitation developments and advanced detector technology enable the use of EDXRF for multielement analysis of plant material and fertilizers, with improved detection limits and reduced measurement time. These features are combined with easy sample preparation and low cost of investment.

Strategies for Achieving the Lowest Possible Detection Limits in ICP-MS

October 01, 2019

Spectroscopy

A laminar flow box for sampling is combined with a positive voltage on the skimmer cone to reduce detection limits to pg/L concentrations in ICP-MS. These improvements reduce the risk of contamination and increase the efficiency of ion sampling and focusing.

Arsenic Speciation in Krill and Other Marine Oils by Liquid Chromatography−Inductively Coupled Plasma-Mass Spectrometry

September 01, 2019

Special Issues

An arsenic speciation method using LA–ICP-MS was developed to provide a more accurate procedure for the determination of arsenic species in marine oils. It was validated for the analysis of five arsenic species in krill oil, and should also prove useful when quantitating inorganic arsenic species in other marine oils.

Method Development with ICP-MS/MS: Tools and Techniques to Ensure Accurate Results in Reaction Mode

September 01, 2019

Special Issues

Method setup and optimization steps are explored to illustrate how an ICP-MS/MS method can be defined and tested to ensure consistent performance. Users can benefit from improved interference removal performance without the complex method development inherent in the use of ion-molecule reaction chemistry

Development of an Analytical Method to Determine Chromium, Iron, Nickel, and Zinc in Mouthwash by ICP-OES and Assessment of Possible Metal Migration from Stainless Steel

September 01, 2019

Special Issues

A simple analytical method, requiring no sample pretreatment, was developed for determination of chromium, iron, nickel, and zinc in mouthwash by inductively coupled plasma‒optical emission spectrometry (ICP-OES). This method allowed the study of potential migration by iron, chromium, and nickel from stainless steel containers.

Rapid Multielement Nanoparticle Analysis Using Single-Particle ICP-MS/MS

May 01, 2019

Spectroscopy

Complex isobaric and polyatomic spectral interferences can be mitigated using triple quadrupole ICP-MS (ICP-MS/MS) with a collision–reaction cell (CRC). This configuration allows for the multielement characterization and detection of smaller nanoparticle sizes.
