Thermal Desorber TDS-1

Thermal Desorber TDS-1

Thermal desorber is intended for volatile and semivolatile organic compounds determination in air and other samples by GC or GC-MS.

Applications
- Volatile and semi-volatile compounds determination in ambient and indoor air by thermal desorption
- VOCs determination in water by purge& trap technique
- Food, flavor and fragrance analysis
- VOCs determination in test chamber, toxins/VOCs extracted from different materials (paints, packages, construction materials, plastics)

Target components previously trapped in a sorption tube are desorbed by heating andrefocused into smaller trap. Trap is heated quickly (up to 2000 °C/min) and narrow band ofanalytes is introduced into analytical column through a heated transfer line. Features• Sample path temperature up to 250°C allows C2 – C20 proven determination. Samplepath is effectively heated on its way from sorption tube to GC in order to avoid heavyanalytes condensation• High heating rate of the trap (up to 2000°C/min) provides instant release ofcomponents and transferring into GC column in a narrow band• Desorption from the trap has reversed direction to sorption flow. This way heavyanalytes avoid strong sorbent in multilayer tubes• Leak test before desorption• Inert sample path prevents from target compounds loss• No cooling agents need with trap Peltier cooling technique• Tube conditioning is carried out by separate gas flow• Built-in digital gas flow controllers provide easy connection to any GC• Simple connection to GC inlet makes it possible to use the same inlet for liquid injection
