Analysis of Automobile Cabin Air by Thermal Desorption GC-MS Using the OPTIC-4 Multimode Inlet

The OPTIC-4 is a multimode injection system with a thermal desorption function that enables performing thermal desorption by placing a Tenax sorbent tube in the injection port liner cup. Direct heating technology enables rapidly heating samples at rates up to 16 ℃ per second, and introducing samples directly into the analytical column without passing them through a transfer line. This means samples can be analyzed with high sensitivity without loss of high-boiling-point or high-adsorptivity components. This datasheet shows the results where volatile organic compounds in automobile cabin air were adsorbed using Tenax TA (2,6-diphenyl-p-phenylene oxide), a sorbent material commonly used for atmospheric analysis, and analyzed by TD-GC-MS.
