HPLC ELSD Method for Analysis Putrescine on Obelisc R Column
Putrescine is a biogenic amine and organic compound with the chemical formula. It is a polyamine, which means it contains multiple amino groups. Putrescine is one of the naturally occurring polyamines found in living organisms and is involved in various biological processes.
Research and Applications:
Putrescine 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
