This Application Note demonstrates the analytical performance of a CDS 7550S thermal desorber coupled to a GCMS for the analysis of TO-17 volatile organic compounds (VOCs) ranging in volatility from Dichlorodifluoromethane to Naphthalene. The data shows that the performance of CDS 7550S meets and exceeds the criteria set forth in US EPA Method TO-17. Detailed instrument method parameters are presented along with clean blank chromatogram, precision, linearity, and calibration curves for various groups of compounds. 7500 Environmental Download

Useful for competitive analysis, product development, regulation, and even forensic analysis, pyrolysis provides a simple way of studying any type of finished polymers by GC-MS. This includes food packaging, like tea bag paper. Tea bag paper is generally made from abaca cellulose fibers. These cellulose fibers are also mixed with synthetic materials to help retain tea particles. In the following examples, about 100 micrograms of papers from different tea bags were pyrolyzed to a setpoint of 600°C with Pyroprobe 6150. 6000 6150 Pyrolysis Pyroprobe Food and Flavor Textiles General Interest Download
