 High Performance Liquid Chromatography (HPLC) Method for Analysis of Butyrylcholine

Butyrylcholine can be retained and analyzed using an Obelisc R mixed-mode stationary phase column. The analysis employs an isocratic method with a simple mobile phase consisting of water, acetonitrile (MeCN), and ammonium formate as a buffer. Detection is achieved using ELSD
