Porous TiC ceramic powder was used as a novel substrate for the surface-assisted laser desorption/ionization mass spectrometry (SALDI-MS) analysis of various environmental pollutants. The porous TiC ceramic powder has a nano-structural morphology with a high surface area, an electrical conductivity, and a photoabsorption at the Nd:YAG laser band of 355 nm. These properties of the porous TiC ceramics suggest having a good compatibility as a substrate for SALDI-MS. Furthermore, the porous TiC ceramic powder can be used as an adsorbent for environmental pollutants. The porous TiC ceramic powder was added to a perfluorooctane sulfonate (PFOS) aqueous solution. The liquid was shaken for 2 h, and PFOS was adsorbed onto the TiC ceramics. The liquid was filtered, and the residue was dried. The obtained powder was fixed on a carbon tape and measured by SALDI-MS in the negative ion mode. As a result, the peak assignable to PFOS (C8F17SO3 −) was detected, and no other significant peaks at m/z 100–500 were observed. As for the other analytes, the ion peaks corresponding to the anions or cations derived from these compounds in the negative or positive ion mode were observed using the same treatments.
