Reliable Indoor Air Methylene Chloride Monitoring
Author(s)GERSTEL
This method showcases a precise, automated workflow for determining methylene chloride in indoor air using thermal desorption GC-MS and GERSTEL’s ISDP module. Automated gaseous internal standard addition ensures highly reproducible tube spiking, while optimized TD and GC-MS parameters provide sensitive and stable quantification—well below OSHA exposure limits. The approach enables accurate baseline monitoring in laboratories, offices, and industrial environments where regulatory compliance and worker protection are essential.
