No matter what matrix is analyzed, what analyte is determined, or which analytical technique is applied, sample preparation is a crucial step. My choice for landmark publication of 2017 brings the benefits of fabric phase sorptive extraction (FPSE) to gaseous samples.
FPSE is a sample preparation approach that was introduced in 2014 by Kabir and Furton (1). When it first came to my attention, I was impressed by its simplicity and efficiency – it requires no matrix modification or clean-up and still achieves great performance, effectively assimilating most of the benefits of solid-phase microextraction while avoiding most of the shortcomings of conventional sample preparation techniques. FPSE’s versatility makes it a suitable technology for a wide range of applications and allows it to resolve diverse analytical problems.
There are already hundreds of sol-gel coatings that can be readily used as sorbents for FPSE, with unique selectivity and affinity towards an extensive range of target analytes. In our laboratory we have used the approach in the analysis of milk and biological fluids for the determination of several compounds, such as endocrine disrupters, antibiotics and antidepressants by HPLC (2)(3)(4)(5)(6), and metals by flame atomic absorption spectrometry (7).
