HPLC Determination of Pentadecafluorooctanoic acid on Newcrom R1 Column

Description

· High Performance Liquid Chromatography (HPLC) Method for Analysis of Perfluorooctanoic acid (PFOA) .

Pentadecafluorooctanoic acid , also known as C8 due to it’s chemical being C 8 HF 15 O 2 , is an industrial surfactant. It is classified by the IARC as a carcinogen to humans. Due to it not breaking down via natural processes, it is also considered a “forever chemical.” It can easily move through soil and contaminate water, leading up to it building up[ in fish and wildlife. Despite that, it has wide use across industries from upholstery, to floor wax, to fire fighting sealants. PFOA was a key point in a renowned legal case of Robert Bilott  against DuPont.

Perfluorooctanoic acid (PFOA) can be retained and analyzed using the Newcrom R1 stationary phase column. The analysis utilizes an isocratic method with a simple mobile phase consisting of water and acetonitrile (MeCN) with a sulfuric acid buffer. Detection is performed using UV.
