“…Several methods have been introduced for the analysis of such mixtures, including NMR [4], FT-IR [5], GC/MS (electron ionization at 70 eV) [6], HPLC/MS (atmospheric pressure chemical ionization) [7], ion chromatography [8], electrospray ionization (ESI) mass spectrometry [9], and ambient sonic-spray ionization (SSI) mass spectrometry [10,11]. From these methods, those involving mass spectrometry are the only approaches that yield molecular level information for the mixtures.…”

“…Unfortunately, the mass spectrometric characterization of hydrocarbons and their mixtures, such as biofuels, is challenging due to the shortcomings of current ionization methods. For example, ESI [12], SSI [10,11], and matrix-assisted laser desorption/ionization [13] (MALDI) are limited to ionization via protonation, deprotonation, and cation attachment [14,15], which means that these methods cannot ionize analytes without easily ionizable functional groups, such as saturated hydrocarbons [16,18]. Ambient analysis of saturated hydrocarbons by using dischargeinduced oxidation in desorption electrospray ionization (DESI) has been reported [19].…”

Saturated and unsaturated, linear, branched, and cyclic hydrocarbons, as well as polyaromatic and heteroaromatic hydrocarbons, were successfully ionized by atmospheric pressure chemical ionization (APCI) using small hydrocarbons as reagents in a linear quadrupole ion trap (LQIT) mass spectrometer. Pentane was proved to be the best reagent among the hydrocarbon reagents studied. This ionization method generated different types of abundant ions (i.e., [M + H] , with little or no fragmentation. The radical cations can be differentiated from the even-electron ions by using dimethyl disulfide, thus facilitating molecular weight (MW) determination. While some steroids and lignin monomer model compounds, such as androsterone and 4-hydroxy-3-methoxybenzaldehyde, also formed abundant M +• and [M+H] + ions, this was not true for all of them. Analysis of two known mixtures as well as a base oil sample demonstrated that each component of the known mixtures could be observed and that a correct MW distribution was obtained for the base oil. The feasibility of using this ionization method on the chromatographic time scale was demonstrated by using high-performance liquid chromatography (HPLC) with hexane as the mobile phase (and APCI reagent) to separate an artificial mixture prior to mass spectrometric analysis.

“…21 To characterize and quantitate the FAME composition of biodiesel, 22 gas chromatography with ame ionization detection (GC-FID) and high-performance liquid chromatography (HPLC) are the two most commonly used techniques. [37][38][39][40][41][42][43] Herein we tested therefore the application of EASI(+)-MS as a screening tool to identify and to quickly establish the L/O ratio from blends of soybean oil and animal fat biodiesel and determine their blend composition. 28 These FFA and FAME proles provide natural chemotaxonomic markers for the parent animal fat or vegetable oil used for the biodiesel production.…”

Easy ambient sonic-spray ionization mass spectrometry (EASI-MS) is applied to the analysis of biodiesel blends prepared from soybean and animal fat biodiesel. A correlation was established between the ratio of abundance of linoleic acid (L) and oleic acid (O) methyl ester ions with the biodiesel blend composition. To compare these results from the EASI-MS technique, the L/O ratio of these blends was also determined using both gas chromatography with flame ionization detection (GC-FID) and gas chromatography with mass spectrometry (GC-MS). Both these classical techniques confirmed that the ratio between the mass fraction of FAME from L and O as measured by EASI-MS is indeed correlated with the blend composition of soybean-animal fat biodiesel.
