TDS-3410A Analysis tube activation device



The TDS-3410A/HTB-3420A desorption tube activation device mainly consists of four parts: desorption tube activation processing components, constant temperature furnace, controller, and timer. Different components can be selected according to the purpose of use. This device is equipped with a deep gas purifier, which can reduce the interference of the purge gas in the simulated sampling of the standard sample. The activation of the desorption tube can be timed and automatically operated. Pyrolysis straw size: 6 (or 1/4 inch) in outer diameter, with unlimited length.
