Details

LC/MS/MS experiments were performed on a home-built ultrahigh-pressure dual on-line solid phase extraction/capillary reverse-phase liquid chromatography (DO-SPE/cRPLC) (Min et al., 2007) that was coupled to a Fourier transform ion cyclotron resonance (FT-ICR, LTQ-FT, Thermo, San Jose) mass spectrometer by means of a home built nanoESI interface.
