4th International Symposium on Beryllium

4th International Symposium on Beryllium

Dr. Erica Cahoon and Cheryl Hicks of High Purity Standards attended the 4th International Symposium on Beryllium Particulates and Their Detection in Colorado from October 1st-4th October 2012.

The main topics for discussions were Chronic Beryllium Disease (CBD), the prevention of beryllium related illness and the detection and identification of beryllium and beryllium containing compounds. CBD is a disease caused from the body’s sensitization to beryllium after exposure to these particulates. There is currently no medical cure for CBD, making preventative actions most important.

Beryllium particulates occur as a result of the natural abundance in the environment and by anthropogenic contaminants. Current sampling methods discussed were ghost wipes, beryllium wipes and air particulate analysis. The most common analytical instrumentation implemented within laboratories are inductively coupled plasma optical emission spectrometry (ICP-OES), inductively coupled mass spectrometry (ICP-MS) and an introduction to optical fluorescence was showcased to demonstrate the competing limits of detection compared to ICP methods. Different statistical methods for data analysis were introduced.

The value of laboratory accreditation, training and quality assurance were emphasized. An overall goal of this symposium is to develop standard methodology for the analytical analysis of beryllium.

Currently, High Purity Standards provides high-fired spiked beryllium filters for in house and inter- laboratory quality assurance testing. High Purity Standards is Guide 34 accredited and manufactures a wide range of certified reference materials to meet the needs of beryllium testing laboratories and analytical laboratories worldwide.
