ULTRA 50:50 & AutoSecure thermal desorption GC(-MS) analysis of VOC / SVOC emissions on sorbent tubes 

Markes thermal desorption systems combine with GC(-MS) to provide cryogen-free and fully method compliant technology for measuring volatile and semi-volatile organics collected on sorbent (e.g. Tenax) tubes during emissions tests.  With manual and fully automated options available, Markes TD systems allow simultaneous analysis of VOCs and SVOCs at concentrations from ppb to percent.  The unique quantitative repeat analysis facility (SecureTD-Q) allows simple validation of analyte recovery through the system.  Markes sorbent tubes and TD systems are fully compatible with ISO 16000-6, EN13419-4 and ASTM equivalent methods and are compatible with all types and size of materials emission chambers / cells.
