      One of the most frustrating things that we here at Biotage have had to deal with when we compare PFAS methods is the lack of a common naming convention for the compounds. It seems like every scientific article and every method contains at least one compound that either uses a new name or a new abbreviation and we have to spend excess time trying to confirm that yes, we're looking at the same compound.  It's so annoying!

      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?

      Welcome back! As the title indicates, this is Part 2 of an ongoing series where we discuss what’s going on with PFAS. For those of you who may not have read Part 1, you missed out on a summary of the controversy surrounding this group of compounds and I would recommend going back and taking a quick read through it to make sure that you’re caught up.

      What are the differences between EPA Method 533 vs 537.1?

      Per- and polyfluoroalkyl substances (PFAS) are a group of harmful organic compounds that are very persistent in structure. What this means is PFAS compounds accumulate in the environment over time as they do not break down easily. This makes it a concern to regulate and test these compounds as they have been shown to have adverse effects. One of the most common ways that someone would come in contact with PFAS is through drinking water.
