The Automatic Thermal Desorption (ATD) Instrument is designed for efficient extraction and analysis of volatile and semi-volatile organic compounds (VOCs/SVOCs) from sorbent tubes, TENAX, and Carbotrap media. The system automates the two-stage desorption process — primary tube desorption followed by cold-trap focusing — and interfaces directly with GC/MS systems for trace-level quantitation down to sub-ppb concentrations.
Features include programmable primary and secondary desorption temperatures, split/splitless injection, automated multi-position sample carousel (up to 50 tubes), and leak-tight connections throughout. Compliant with EPA TO-17 and ISO 16017 methods. Compatible with major GC brands via standard transfer line connections.
