Short Path Thermal Desorption Model TD-5

Figure 1: TD-5 system.

--A Short Path Thermal Desorption (SPTD) system for the analysis of volatiles and semi-volatiles by GC and GC/MS.

NEW TD-5 system: The TD-5 (the successor to the TD-4) is like the TD-4 but is controlled by software on the PC and has a few minor hardware changes (e.g. larger heaters).

Summary: The SIS TD-5 Short Path Thermal Desorption System thermally extracts volatile and semi-volatile organics from solid, liquid and gas samples for analysis by GC and GC/MS. It consists of a Thermal Desorption Unit (Figure 1 - right) and an Electronics Control Unit, which interfaces to Windows-based control software running on the PC (Figure 2). The Thermal Desorption Unit sits directly on top of the GC injection port of most GCs, where it introduces extracted volatile and semi-volatile directly into the GC injection port and column. Due to its "short path" of sample flow, this new system overcomes the shortcomings of previous desorption systems by eliminating transfer lines, which are easily contaminated by samples, and by providing the optimum shortest path delivery (and therefore maximum sensitivity) of samples to the GC injector, i.e. direct injection into the GC, like using a GC injection syringe. The Electronic Control Unit permits automated operation including automatic injection, timed desorption, temperature ramp of heater blocks, control of GC Cryo-Trap Accessory, and remote starting of GC's, mass spectrometers, and recorders.
