Ready-To-Go Qualification Tools for Trace Metals in Pharma Analysis

  
  
  
  
  
  
compliance for USP 232 233

It’s appropriate I am writing this blogpost in December 2014; exactly one year away from the start of new regulation from U.S. Pharmacopeial Convention (USP) that mandates the testing of fifteen trace elements (metals) in pharmaceutical products from 1st December 2015 onwards as per USP <232> & <233> (link to USP site on these regulations).

So, the clock is now ticking towards this date and I’m meeting nutraceutical, pharmaceutical, and biopharmaceutical manufacturers across the globe that are making preparations to meet these new pharmaceutical regulations.

Overcoming Interference Challenges During Trace Elemental Analysis

  
  
  
  
  
  
trace elemental interference in ICP-OES, ICP-MS, ICP-MS analysis

Applications for trace elemental analysis are quite common, ranging from toxic metal analysis in water, lead analysis in toys, to trace metals analysis for semiconductor, with detection level from part per million (ppm) to sub part per trillion (ppt). The trace contamination of certain elements can lead to severe health problems or cause defect in products.

ICP-MS Arsenic Speciation in Rice: The Media and The Science

  
  
  
  
  
  
quantification of inorganic arsenic in rice

Recently I watched a very thought provoking documentary by Dispatches on Channel 4 here in the UK which was all about arsenic in rice and rice products (link to U.S. FDA page). As I have a keen interest in ion analysis, I was intrigued to see if the science is consistent with the media story, so took on some research of my own.

Chromatography and Sample Preparation Terminology Guide

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.

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.
