Agilent has partnered with Markes International to bring a complete system for the analysis of volatile and semivolatile compounds in air. The system consists of Agilent's GC and GC/MS instruments combined with Markes' UNITY, ULTRA TD, and UNITY-Air Server products, providing a versatile and state-of-the-art solution for air analysis. The UNITY thermal desorber is the core of the TD system, offering long-term reliability and high analytical performance for routine and challenging applications. It includes sample protection features required for compliance with international standard methods, as well as a unique repeat analysis capability called SecureTD™. Markes' thermal desorption systems are compatible with industry standard sorbent tubes, canisters, bags, and on-line air sampling. The system is fully supported by Agilent's renowned sales and service organization.
Agilent has partnered with Markes International to provide the UNITY thermal desorption system for analyzing volatile and semivolatile compounds in air. The system is designed for compatibility with Agilent's GC and GC/MS instruments and features a single-tube thermal desorber with electrically-cooled focusing traps that eliminate the need for liquid cryogens. Key capabilities include the retention of ultra-volatile components like acetylene and efficient desorption of wide boiling range samples.
