Overview

The AutoTDS VPro fully automatic thermal desorption instrument is a 24 bit low-temperature secondary fully automatic thermal desorption instrument with diversion function, which can store multiple operating methods. The gas circuit adopts a combination of electric six way valves and solenoid valves, which can be programmed to automatically complete five processes: dry blowing of 24 adsorption tubes (removing oxygen and water vapor from the sampling tube), primary desorption low-temperature enrichment (optional diversion), secondary desorption, injection, and blowback. 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.

Key Features:

Strong universal performanceCan be used with any brand of gas chromatograph（GC）And（GC-MS）Joint use to achieve control information interconnection.
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.
Equipped with electronic flow control function, it automatically controls the blowing flow rate and back blowing flow rate.
Cold trap refrigerationMeet the majority of low-temperature enrichment needs.
The temperature rise of the capture trap is achieved through direct resistance heating
All sample pipelines and six valve controllable temperature heating eliminate system cold spots and reduce sample loss.
diversion/No diversion, one desorption can switch between diversion and no diversion, and the diversion ratio can be manually adjusted.
Equipped with automatic leak detection and fault alarm function for sample tubes: Before 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.
Direct accessGCCarrier gas path, no need to occupy the injection port.
No pneumatic components, no need to drive the air source.
