“…In a few cases, esters are derived from unbranched carboxylic acids and iso-branched short-chain alcohols (e.g. [30][31][32][33]64) and are included here. Fig.…”

Use of ultrasound in gradient elution of Polycyclic Aromatic Hydrocarbon mixtures by HPLC

“…4 Ryoo et al investigated ultrasound-assisted separation of optical isomers and observed a reduced elution time and improved selectivity of chiral separation in chiral chromatography. [5][6][7] However, the observed improvement in ultrasound-assisted chiral separation was small, and the underlying mechanism of ultrasonic waves in chiral separation remains unidentified. A recent ultrasound-assisted extraction study attempted to quantitatively analyze the amount of ultrasonic irradiation penetrating through the empty stainless steel (SS) and polyether ether ketone (PEEK) columns, acting as the extraction vessels, by manipulating various ultrasonic parameters.…”

“…Various external factors can be used to adjust the retention of a sample in chromatography without changing the stationary or mobile phases. These external chromatographic factors include temperature, 1,2 ultrasound, [3][4][5][6][7][8] magnetic force, 9 and optical force. 10 In particular, to separate complex mixtures, various factors can be used for an effective separation via gradient methods in gas chromatography, 1 supercritical fluid chromatography, 11 and high-performance liquid chromatography (HPLC).…”
