If you consider SOA formation to be of low importance for your application, the subset of the CONC file PM species that are included in your CMAQv53 SA output file when enabling the SULFATE, NITRATE, AMMONIUM, EC, OC, and PM25_IONS tag classes should be sufficient. The remaining CONC file PM species (AALK1J, AALK2J, AXYL1J, AXYL2J, AXYL3J, ATOL1J, ATOL2J, ATOL3J, ABNZ1J, ABNZ2J, ABNZ3J, ATRP1J, ATRP2J, AISO1J, AISO2J, ASQTJ, AORGCJ, AISO3J, AOLGAJ, AOLGBJ) are SOA species, so if you do not consider them important for your application, you likely need not worry about their absence in your SA files.
