      When learning that you may be transitioning to a newer revision of an EPA method some thoughts may come to mind such as: it took so long to perfect this sample preparation method, or I hope they have some improvements and or greater flexibility allowances in this revision. Well, that is exactly what we will touch upon in this blog post - sample preparation improvements.
