Main functions

1.The TD100-xr™ is a highly efficient and automated thermal desorption system that can quickly and automatically analyze up to 100 3½-inch adsorption tubes in a single run sequence.
2.Compared with other thermal desorption systems, the TD100-xr quantitatively recollects samples for reanalysis or preservation, enhancing the safety of the samples. The cold trap of the TD100-xr is electrically refrigerated, which can save the cost and cumbersome procedures of liquid refrigerants.
3.It can detect volatile and semi-volatile organic compounds within the concentration range from percentage level to sub-parts per trillion (ppt) level (from C2 to C44, including reactive and thermally unstable substances).
