| http://www.w3.org/ns/prov#value | - The electrospray ionization (ESI) settings were as follows: capillary voltage, 3.5???kV; cone voltage, 40???V; desolvation gas-flow (Argon gas), 800???L/hr; cone gas-flow, 20???L/hr; collision energy, 20???V. To determine concentrations of the free forms of phenols, we followed the procedures described above except enzyme hydrolysis.2.3.
