As part of the ARB-sponsored Carbonaceous Species Methods Comparison Study (CSMCS) in Glendora, CA, from August 11-21, 1986, time-integrated, ambient samples were collected in stainless steel canisters. Five samples per day were collected, ranging from 4 to 8 hours according to the CSMCS protocol. The species measured included CO, CH/sub 4/, CO/sub 2/, H/sub 2/, and the C/sub 2/ through C10 hydrocarbons. In addition, N/sub 2/O, the halocarbons F-12, F-11, F-113, CHCl/sub 3/, CH/sub 3/CCl/sub 3/, CCl/sub 4/, C/sub 2/HCl/sub 3/ and C/sub 2/Cl/sub 4/ were measured. Four gas-chromatograph systems were used to quantify these species. The report contains tables of concentrations of the species measured at the South Coast Air Basin site during smoggy summer conditions.
