If you are a chemist that is either a beginner or an expert in extracting per-and polyfluoroalkyl substances (PFAS) there are always going to be questions that come up after the extraction has taken place. Most often, questions occur at the concentration step. Such topics include water bath temperature, extract dryness, evaporation rates, and even water in the extract. How can one or all of the topics impact your analysis and where are good starting points?

When working with regulated environmental methods have you ever asked yourself why are all these extracts concentrated down to one milliliter (mL) final volume? This is true for most soil and aqueous methods. Of course, a few methods will require a more diluted final volume but not many.

“I love doing maintenance. It’s the best part of my week” – said nobody ever. Let’s be honest. We all dread performing maintenance. Why? It’s boring. I’m a chemist and I’d rather spend my time using my instrument than maintaining it. It seems unnecessary. I’m a fan of what I call “sensory maintenance” – that water looks pretty clean, that pump sounds pretty good.

It is question and answer time and we are starting with TurboVap® evaporators and their use in an environmental lab. The TurboVap® evaporation system by design utilizes a patented gas vortex shearing technology. You may be asking yourself, “what does that mean?” I know I did when I first heard about it! Read on to learn more about what this does for your lab evaporation.
