Auto TDS - Ⅴ automatic 10 / 20 bit secondary thermal desorption instrument
Tds-20 is a fully automatic pyrolyzer.
Auto TDS - Ⅴ fully automatic 10 / 20 position secondary thermal desorption instrument can automatically complete the desorption and sample injection analysis process of 10 (20) adsorption tubes by linkage with chromatography.
Autotds - Ⅴ fully automatic 10 / 20 position secondary thermal desorption instrument can add normal temperature secondary desorption components or low temperature secondary desorption components according to the user's needs, so as to improve the sensitivity and improve the chromatographic peak type.
Autotds - Ⅴ fully automatic 10 / 20 position secondary thermal desorption instrument is applicable to hj-644-2013 determination of volatile organic compounds in ambient air, adsorption tube sampling thermal desorption gas chromatography-mass spectrometry and HJ / T Methods for the determination of volatile organic compounds in indoor air by thermal desorption gas chromatography 50325-2010 code for indoor environmental pollution control of civil construction engineering, hj734-2014 determination of volatile organic compounds in waste gas from stationary pollution sources solid phase adsorption thermal desorption / gas chromatography-mass spectrometry and other standards.
The main features of autotds - Ⅴ automatic 10 / 20 bit secondary thermal desorption instrument are as follows
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 the operation 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;
Synchronous interface is provided to start chromatography and workstation at the same time of injection.
The lowest refrigeration temperature is - 30 ℃ (room temperature is 20 ℃), which can meet most of the requirements of low temperature enrichment.
The trap was heated by direct resistance, and the heating rate was more than 2400 ℃ / 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.
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.
