Study of overload for basic compounds in reversed-phase high performance liquid chromatography as a function of mobile phase pH (2006)
Journal Article

The retention and overloading properties for eight basic solutes and two quaternary ammonium compounds were studied over the pH range 2.7-10.0 using phosphate and carbonate buffers. At low pH, a hybrid inorganic-organic silica-ODS phase (XTerra RP-18...

Overload for ionized solutes in reversed-phase high-performance liquid chromatography (2006)
Journal Article

Overloading occurs for submicrogram quantities of ionized solutes particularly when using low ionic strength mobile phases at low pH (e.g., formic acid), even with highly inert silica RP-HPLC columns of normal dimensions. Much higher loads can produc... Read More about Overload for ionized solutes in reversed-phase high-performance liquid chromatography.
