(equipped with 24 bit, secondary low temperature capture and desorption function)
Determination of organic volatiles in automobile textiles by Shanxi thermal analysis instrument Introduction:
The tds-24 full absorption pyrolyzer is a multi-function automatic pyrolyzer.
In addition, the temperature of the desorbing tube can be set by using the temperature of the desorbing tube, the temperature of the second desorbing tube, and the temperature of the desorbing tube can be set automatically At the same time, the chromatograph and workstation can be started at the same time.

Automatic 24 bit low temperature secondary thermal analyzer Main features:
Strong general performance: it can be combined with any brand gas chromatograph (GC) and (GC-MS) to realize the interconnection of control information.
Simple operation, easy to use, software control, high degree of automation: just put the sample tube into the thermal desorption instrument, all operations and control are completed by the control software, so the sample repeatability is good; the design of large touch LCD screen in the host can track the temperature and operation command in the whole process.
The system can store up to 10 running methods.
Synchronous interface is provided to start chromatography and workstation at the same time of injection.
Electronic flow display, purge flow and back flow
The lowest refrigeration temperature is - 35 ℃ (room temperature is 20 ℃), which can meet most of the requirements of low temperature enrichment.
The trap is heated by direct resistance, and the heating rate is more than 3000 ℃ / min.
All pipelines and six way valves can be heated at controlled temperature to eliminate the cold point of the system and reduce sample loss.
Split / no split, one-time desorption can be switched between split and no split, the split ratio is manually adjusted.
With sample tube automatic leak detection and fault alarm function: before testing each sample, it can automatically check whether the sample tube and system gas path are installed properly.
The sample pipeline is treated with silylation inert treatment of stainless steel pipe to reduce pollution residue.
It is directly connected to the GC carrier gas path without occupying the injection port.
No pneumatic components, no need to drive air source.
