(MONROEVILLE, Pa., November 19, 2012) RJ Lee Group, Inc.’s Mr. Drew R. Van Orden, Mr. Matt Sanchez, and Mr. J. Michael Wilmoth wrote and published an article discussing the effects of sample preparation of asbestos in The Microscope. The article, entitled “Effect of Sample Preparation on Observed Airborne Fiber Characteristics,” was published in Volume 60, Issue 2 of the publication, which is a peer-reviewed journal focusing on ideas and advancements related to microscopy.
In the publication, the authors review proposed changes to the ASTM D7200 method. The authors state that the changes are based upon inappropriate strategies for preparing samples, and that sample preparation procedures used in some laboratories destroy key properties of asbestos. The authors conclude that the effects of preparing samples must be considered when creating or revising analytical procedures.
