New york state department of environmetal conservation PAMS monitoring system using a 3-column, double identification GC

摘要

New York State conducted its 1995 PAMS measurements for New York City in the Bronx borough (New York Botanical Gardens) using a Perkin-Elmer ATD-400 Thermal Desorbtion Unit with an 8000 Series Gas Chromatograph. Data was collected in New York City, transferred to Albany, and processed in the central office. The system was checked on a dalily basis from Albany to verify operation. Quality assurance for the system was provided by collecting a one hour collocated canister sample every day with analysis performed in Albany using a GC-MS system. The normal configuration for the Perkin-Elmer system uses only two colunms, a PLOT column to separate low weight hydrocarbons (C_2-C_5) and a BP-1 column to separate higher wieht hydrocarbons (C_6-C_(10)).
