Ion Chromatography Improves Chromium Speciation in Drinking Water

  
  
  
  
  
  
chromium in drinking water infographic

Did you know that new laws for measuring chromium in water are on the horizon and, in particular, hexavalent chromium (Cr6+) is under evaluation for new legislation by the U.S. EPA (link to US EPA page on recommendations for Cr6+ monitoring) and the European EFSA (link to EFSA Scientific Opinion page on Cr6+). 

Ion Chromatography Improves Analysis of Lithium Ion Batteries!

  
  
  
  
  
  
analysis of lithium ion battery electrolytes

It does seem I have fuel cells on my mind but when I found that I had not written about a really well received webinar on the use of multiple chromatography techniques for the analysis of lithium ion batteries, I had to feature it before I forgot again! The webinar is now on-demand so you can play it at your leisure once you fill out a quick registration form. Click the image on the right or the title of the webinar below to access the webinar.

Chromatography Monitoring as per U.S. EPA UCMR 3: Two Webinars

  
  
  
  
  
  
UCMR 3 inorganic and organic contaminant analysis

The two-parts of this upcoming webinar series presented in this post cover multiple chromatography techniques (gas chromatography-mass spectrometry, liquid chromatography-mass spectrometry, ion chromatography, and Liquid Chromatography Electrospray Ionization Tandem Mass Spectrometry) for the monitoring of inorganic and organic contaminants as per the U.S. EPA's Unregulated Contaminant Monitoring Rule 3 (UCMR 3) (link to U.S. EPA page). Both webinars will feature a customer case study from Eurofins Eaton Analytical Inc.; Dr. Andy Eaton, Vice President and Technical Director at Eurofins Inc. will be in a discussion with Dr. Richard F. Jack, our NA Environmental Market Manager at Thermo Fisher Scientific Inc.

Chromatography Solution Online Center Now Open!

  
  
  
  
  
  
liquid chromatography, ion chromatography, gas chromatography, and chromatography software

Do you know about our collaboration with Chromatographyonline.com in presenting an online Chromatography Solution Center to serve as a resource for chemists, scientists, and researchers by presenting the latest developments and applications, in chromatography?

Ion Chromatography & ICP-MS Analysis of Hexavalent Chromium in Toys

  
  
  
  
  
  
hexavalent chromium in toys

Did you know that the European Union directive for toy safety (Directive 2009/48/EC [downloadable PDF]) is currently under revision and proposes trace level determinations of several elements including hexavalent chromium (Cr (VI)) (link to Wikipedia page) in toy materials that may affect exposed children?

Ion Chromatography Solutions for IC-ICP-MS Speciation Analysis (2)

  
  
  
  
  
  
trace element food analysis using ion chromatography

After last week's post which featured a  customer method that combines ion chromatography with Inductively Coupled Plasma Mass Spectrometry (IC-ICP-MS) for trace elemental analysis of arsenic in apple juice, infant formula, and food (link to post), I am pleased to present an application notebook, titled, Speciation Applications Summary Ion Chromatography, (link takes you to registration page that requires a minute to fill out before you can  download the PDF) that provides more applications and details for your benefit.

Ion Chromatography Speeds Arsenic Speciation in Food Matrices (1)

In this first of a two-part series on speciation analysis using ion chromatography with Inductively Coupled Plasma Mass Spectrometry (IC-ICP-MS), I am pleased to present a customer method for the fast determination of arsenic speciation in food matrices. (The second blog post will present an application notebook with speciation analysis for arsenic, chromium, idodide, and mercury.)

In case you have not been following the issue of arsenic in our water and food supply, here's some troubling news in the form of new studies on the toxicity of arsenic. Turns out arsenic, which has been known to be fatal in high doses, is now found to be damaging to human health at even low doses! (link to detailed New York Times blog post on topic.) By the way, while arsenic is ubiquitous in the environment in the form of inorganic and organic compounds, the inorganic species arsenite (As(III)) and arsenate (As(V)) are highly toxic to human health.


Next Generation Ion Chromatography Suppressor Introduced!

We just released a new ion chromatography suppressor (Thermo Scientific Dionex ERS 500 Electrolytically Regenerated Suppressor) and I thought our blog readers would be interested in learning about the new features of this particular suppressor.

Accelerated Solvent Extraction Helps Identify the Anthropocene Era!

  
  
  
  
  
  
sample prep for chromatography

Do you know about the Anthropocene era? It is the current geologic era and is considered to be an era in which humans have made a significant impact on the Earth's ecosystem. While some scientists believe it to have begun with the Industrial Revolution in the late 18th century, other scientists are arguing for it to have begun with the beginning of agriculture and the Neolithic age, some 14,000 years ago.

Ion Chromatography: Mercury Contamination in Herbal Medicines

  
  
  
  
  
  
mercury speciation analysis

The ion chromatography (IC) application presented in this blog post was the result of a mercury poisoning cluster in the United States in which multiple people in the state of Iowa became ill as a result of taking herbal medicines from India, The researchers dealing with the poisoning contacted our researchers to not only identify the mercury species but also help solve a real whodunit piece.
