UNITY 2 is a full functionality, single tube, two-stage desorber operating cryogen-free and offering unlimited upgrade routes. It offers unique application versatility:    
   

Compatibility with reactive analytes which require low flow path temperatures (e.g. mercaptans, CW agents and explosives)   

Uniquely effective cryogen-free retention of ultra-volatiles such as acetylene from over 1.5 L of air (Boosts sensitivity for key online air monitoring applications such as ozone precursors)   

Quantitative retention of high-boilers such as phthalates, 5/6 ring PAHs and n-C40   

Simultaneous analysis of volatiles and semi-volatiles.   

Direct desorption of materials as well as desorption of sorbent tubes   

Accessories available for interfacing headspace samples, canisters, bags and online air/gas streams   
   
Quantitative recovery of analytes from sample tubes can be validated using SecureTD-Q (quantitative re-collection for repeat analysis) per standard methods
