Happy Tuesday! This week’s question will focus on one of the EPA methods used for extracting semivolatile organic compounds (SVOCs) prior to analysis by GC/MS. Are you ready to Expand Your Horizon?
Today’s question: EPA Method 8270 outlines a method for extracting and quantifying a number of compounds, of which hexachlorocyclopentadiene is one. However, this compound can be difficult to recover. Why? (choose all that apply)
(a) It is photoreactive and decomposes when exposed to light
(b) It is chemically reactive and reacts with certain organic solvents
(c) It has a relatively high vapor pressure and evaporates a bit at room temperature
(d) It is susceptible to thermal degradation
(e) None of the above
Submit your answer in the comments below! (need a hint? The answer isn’t “none of the above”)
Stay tuned next Tuesday….
