Ion pair reagents are vital as a mobile-phase additive when structurally or chemically or polarity wise inseparable closely connected compounds are for being divided [21, 22]. As an example, if a combination of ionic and nonionic analyte(s) obtaining precisely the same polarity and same retention time is needed being separated, commence by optimizi
