-hydroxybenzoic acid—with a nonpolar C18 column employing a aqueous mobile phase that includes a buffer of acetic acid and sodium acetate. Retention instances are shorter for fewer acidic cell phases since Just about every solute is existing in an anionic, weak base kind that may be a lot less soluble within the nonpolar stationary stage.They con
