Overview

The AutoTDS-VI dual channel fully automatic thermal desorption instrument is a 24 bit dual channel low-temperature secondary fully automatic thermal desorption instrument. The gas path adopts an electrically controlled multi-channel switching valve and an electromagnetic valve combination, which can be programmed to automatically complete the four processes of primary desorption, secondary low-temperature enrichment, secondary desorption, injection and blowback of the dual channel 24 adsorption tubes. The primary desorption temperature, secondary desorption temperature, cold trap temperature and pipeline heating temperature can be independently set, and synchronous signals can be output during injection to simultaneously start chromatography and workstation. Applicable to standards such as "HJ644-2013 Determination of volatile organic compounds in ambient 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/T18883-2022 Indoor air quality standards", "HJ583-2010 Solid adsorption/thermal desorption gas chromatography", "GB 50325-2020 Code for indoor environmental pollution control of civil construction engineering", "HJ734-2014 Determination of volatile organic compounds in fixed source exhaust gas - Solid phase adsorption - Thermal desorption/gas chromatography-mass spectrometry", etc.

Product Details

Key Features:

1. Strong universal performance: can be used in combination with any brand of gas chromatography (GC) and gas chromatography-mass spectrometry (GC-MS).

2. By combining an electronically controlled multi-channel switching valve with an electromagnetic valve, desorption can be carried out simultaneouslytwosample tube.

3. 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;Large size in the hostTouch LCD screenDesigned to track temperature and operational commands throughout the entire process.

4. Provide a synchronization interface to start chromatography and workstation simultaneously with sample injection.

5. Cold trap adoptsSemiconductor refrigeration+air coolingThe refrigeration temperature can reach -30 ℃ (at room temperature of 20 ℃), meeting most low-temperature enrichment needs.

6. The temperature of the capture trap is raised usingDirect resistance heating，heating rate>3000℃/divide.

7. All sample pipelines and multi-channel switching valves can be temperature controlled and heated, eliminating system cold spots and reducing sample loss.

8. With sample tubeAutomatic leak detectionFunction: It can automatically check whether the sample tube is properly installed before testing each sample.

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