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 hand领 and
transporting.
Rapid cryogenic (CO2 or LN2) coo领 and heating of the GC
column head for improved chromatographic resolution
(optional Cryo-Trap accessory).
Functions/Convenience
Mounts overtop most GC injection portseasily 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
