This work shows that CE-MS can reach same sensitivity as HPLC-MS, when it is peformed in the ITP-MS mode. By combination of ITP-ESI-MS with an offline SPE preconcentration step and optimization of MS signal collection, LODs below 2x10-12 M can be reached, corresponding to of 0.6 ng/L of diclofenac (Dic) and 0.4 ng/L of ibuprofen (Ibu), compatible to that of SPE-HPLC-MS.
