One of the most important advantages of inductively coupled plasma atomic emission spectrometry (ICP-AES) is that it can analyze aqueous and organic solutions. This makes it an ideal technique for the petroleum/petrochemical industry, which generates a wide variety of aqueous and organic sample types. With proper solvent selection, the heavy end of the barrel as well as the light fractions of crude, and crude oil itself, can be analyzed. ICP-AES has been a well-established technique in the petroleum analysis laboratory since the 1970s. The author's laboratory at ExxonMobil (then Exxon Research and Engineering Company) in Baytown, Texas, ordered one of the first commercial ICP-AES instruments and took delivery in early 1976. This Jarrell-Ash (now Thermo Fisher Scientific, Inc.) direct-reading arc spectrometer fitted with an ICP source was the first ICP-AES installed in the petroleum industry. It served us well for nearly 25 years .
