The 2-Minute Rule for method development

Ion pair reagents are essential being a mobile-section additive when structurally or chemically or polarity wise inseparable carefully relevant compounds are to get divided [21, 22]. One example is, if a mixture of ionic and nonionic analyte(s) possessing a similar polarity and identical retention time is needed to be divided, begin by optimizing f
