The AutoTDS-V fully automatic thermal desorption analyzer is a 20 position fully automatic thermal desorption analyzer that can automatically complete the desorption and injection analysis process of 20 adsorption tubes in conjunction with chromatography. We can add room temperature secondary desorption components or low-temperature secondary desorption components according to user needs to improve sensitivity and chromatographic peak shape.

Applicable to standards such as "HJ-644-2013 Determination of Volatile Organic Compounds in Environmental Air - Adsorption Tube Sampling - Thermal Desorption Gas Chromatography Mass Spectrometry", "HJ/T 400-2007 Sampling and Determination Methods for Volatile Organic Compounds and Aldehydes and Ketones in Vehicles", "GB/T18883-2002 Indoor Air Quality Standards", "HJ583-2010 Solid Adsorption/Thermal Desorption Gas Chromatography", "GB 50325-2010 Code for Indoor Environmental Pollution Control of Civil Building Engineering", etc.

Features:

• Strong universal performanceCan be used with any brand of gas chromatograph（GC）And（GC-MS）Joint use, realizing the interconnection of control information;
• Easy to operate, convenient to use, fully controlled by software, high degree of automationSimply place the sample tube into the thermal desorption instrument, and all operations and controls are completed by the control software, resulting in good sample repeatability;The large touch LCD screen design in the host can track temperature and operation commands throughout the process;
• Provide a synchronization interface to start chromatography and workstation simultaneously with sample injection.
• Cold trap adoptsSemiconductor refrigeration+air cooling， The maximum low cooling temperature can reach -30 ℃ (at room temperature of 20 ℃), meeting most low-temperature enrichment needs.
• The temperature rise of the capture trap is achieved through direct resistance heating，heating rate>1800℃/divide.
• All pipelines and six way valves are temperature controlled for heating, eliminating system cold spots and reducing sample loss.
• Equipped with automatic leak detection and fault alarm function for sample tubesBefore testing each sample, the sample tube and system air circuit can be automatically checked for proper installation.

The sample pipeline adopts silane inert treatment stainless steel pipes to reduce residual pollution.
