快速热解析装置

快速热解析装置可以直接放在色谱进样口的上面，可以对进入进样口和色谱柱的极性非极性样品进行快速解析，使样品以最短的理想路径进入色谱，避免样品污染进样系统。

Samples to be analyzed are collected into stainless steel
desorption tubes (either glass lined GLT or silco-treated)(Fig.1).
A solid sample of interest may be packed directly into the tube and
subjected to direct thermal desorption. Alternately, the tube may
be packed with adsorbent resin such as Tenax™ TA or activated
carbon for indirectly trapping analytes from liquid or air samples.

Features

Analytical quality
• High sensitivity thermal desorption and direct thermal
extraction of solid, liquid, and gas samples
• No memory effects – each sample has its own independent
and “short” flow path from sample to GC, eliminating transfer
lines as a source of contamination
• Stainless steel sample tubes (glass-lined GLT or silco treated)
are inert to samples and strong for sample handling and
transporting.
• Rapid cryogenic (CO2 or LN2) cooling and heating of the GC
column head for improved chromatographic resolution
(optional Cryo-Trap accessory).
Functions/Convenience
• Mounts overtop most GC injection ports—easily removable
and transferable.
• Automatic injection and desorption of sample into GC
(pneumatic driven injector).
• NEW - Windows-based software for control and monitoring
of the system
• NEW - Seamless integration into Agilent ChemStation
