N2 - The analysis of the inorganic content of bio-oils has not been widely reported in the literature. In this work, the analytical methods employed for the quantification and speciation of inorganic species in bio-oils are summarized. Total inorganic analysis of bio-oils is commonly performed using inductively coupled plasma optical emission spectrometry and inductively coupled plasma mass spectrometry techniques; however, other quantitation techniques are compiled and discussed in this review. Additionally, the few studies that have recently been reported on the inorganic speciation of bio-oils by supercritical fluid chromatography–inductively coupled plasma mass spectrometry, gel permeation chromatography–inductively coupled plasma high-resolution mass spectrometry, and electrospray ionization Fourier transform ion cyclotron resonance mass spectrometry are also addressed. Cumulatively, the reports suggest that the lack of standard analytical methods in the total inorganic analysis of bio-oils is a major contributor to inaccurate results. Thus, future research with analytical methodologies already applied in crude oils should be adapted to account for the unique bio-oil(s) matrix. Such a strategy offers a path toward more accurate inorganic speciation/quantitation of inorganics in bio-oils, which might be the key to the understanding of production problems, storage stability, and upgrading processes commonly encountered with such samples.
