When preparing your extracts for analysis, it is important to know which instrument to use and why you should be using that specific one. Of course, we know that each EPA method dictates which analysis instrument must be used within each method, however, we will be determining why that option was chosen in the first place in this blog post!
7 Horrible Mistakes You’re Making with Solid Phase Extraction

Solid phase extraction (SPE) is a powerful sample preparation tool that makes it possible to extract semi-volatile organic compounds with varying physical and chemical properties. When used properly, this tool will simultaneously extract hundreds of analytes from the most challenging sample matrices. When used improperly – well, this tool can quickly become as effective as using a hammer to paint the walls in your house.
What is the best way to dry extracts for drinking water samples?
