Introduction to a dual 20 position low-temperature fully automatic thermal desorption instrument, also known as a thermal desorption instrument:

The gas circuit of the dual 20 position low-temperature fully automatic thermal desorption instrument adopts a combination of dual electronic control six way valves and solenoid valves, 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 20 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 the chromatography and workstation.

A dual 20 position low-temperature fully automatic thermal desorption instrumentApplicable 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/T18883-2002 Indoor air quality standards", "HJ583-2010 Solid adsorption/thermal desorption gas chromatography", "GB 50325-2010 Code for indoor environmental pollution control of civil construction engineering", "HJ734-2014 Determination of volatile organic compounds in fixed pollution source exhaust gas - Solid phase adsorption - Thermal desorption/gas chromatography-mass spectrometry", etc.

A dual 20 position low-temperature fully automatic thermal desorption instrumentcharacteristic:

• Adopting a dual electronic control six way valve, two sample tubes can be desorbed simultaneously

• Easy to operate, convenient to use, fully controlled by software, high degree of automationSimply place the sample tube into the domestically produced thermal desorption system, 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 operation commands throughout the entire process

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

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

• The temperature of the capture trap is raised usingDirect Resistance Heating，heating rate>2400℃/divide

• All pipelines and six way valves are temperature controlled for heating, eliminating system cold spots and reducing sample loss

• With sample tubeAutomatic leak detectionFunction: Automatically check if the sample tube is properly installed before testing each sample

• The sample pipeline adopts silane inert treatment stainless steel pipe to reduce residual pollution
