How to improve the lifespan of an automatic thermal desorption device

The automatic thermal desorption device is a sample preparation device that is often used in conjunction with a gas chromatograph. A58Textile Testing Instruments, Testing Equipment Manufacturer


The sample is thermally desorbed into a large syringe, then the sample is manually withdrawn and injected for gas chromatographic analysis. A58Textile Testing Instruments, Testing Equipment Manufacturer


The automatic thermal desorption device mainly consists of four parts: A58Textile Testing Instruments, Testing Equipment Manufacturer


desorption activation treatment furnace, large constant temperature syringe heating furnace, double temperature controller and manual operation. A58Textile Testing Instruments, Testing Equipment Manufacturer


In addition to the desorption furnace, the automatic thermal desorption device is also equipped with a large constant temperature furnace with syringe heating to fulfill the purpose of a multi-function machine.A58Textile Testing Instruments, Testing Equipment Manufacturer


Therefore, compared to the previous similar desorption devices, it has simplified operation, improved work efficiency and analysis accuracy. A58Textile Testing Instruments, Testing Equipment Manufacturer


The automatic thermodabsorption device adopts the integrated design of absorption activation treatment furnace and large constant temperature syringe heating furnace. One machine is versatile, greatly improving the cost performance and running cost of the automatic thermal desorption device;A58Textile Testing Instruments, Testing Equipment Manufacturer


The same sample can be injected repeatedly, avoiding the adverse effects of misoperation during the sampling or analysis process;A58Textile Testing Instruments, Testing Equipment Manufacturer


When measuring, you can use cheap activated carbon adsorption tubes, etc.; Compared with similar thermal desorption devices ( device), the installation of the desorption tube is simple and the operation without dead volume is realized;A58Textile Testing Instruments, Testing Equipment Manufacturer


Automatic thermal desorption device is especially suitable for beginners who are not familiar with chromatographic analysis. A58Textile Testing Instruments, Testing Equipment Manufacturer


The automatic thermal desorption device requires maintenance after a period of use, including:m ensure the normal operation of its subsequent work and prolong its service life. A58Textile Testing Instruments, Testing Equipment Manufacturer


Next, let's take a look together at how to maintain the automatic thermal desorption device. A58Textile Testing Instruments, Testing Equipment Manufacturer


1. Operators should complete appropriate training and read the relevant technical information of automatic thermal desorption equipment in detail. A58Textile Testing Instruments, Testing Equipment Manufacturer


2. The consumable parts of the automatic thermal desorption device should be replaced regularly. A58Textile Testing Instruments, Testing Equipment Manufacturer


3. Electrical equipment should be serviced regularly. A58Textile Testing Instruments, Testing Equipment Manufacturer


4. The original components, power supply, sensor, touch screen, etc. of the electrical control part should be well insulated, rat-proof and temperature-controlled. A58Textile Testing Instruments, Testing Equipment Manufacturer


Reduce the damage to vital parts caused by oxidation, aging, leakage, short circuit and open circuit. A58Textile Testing Instruments, Testing Equipment Manufacturer


5. The knife edges, scales and pointers of various MesInstruments should be protected from damage, kept clean and calibrated regularly by the measurement department. A58Textile Testing Instruments, Testing Equipment Manufacturer


6. Due to wear, rust, dust, oil, breakage, damage, falling into foreign objects, looseness or improper operation of the mechanical system, the automatic thermal desorption device will crash, slip, vibrate, out of sync, and the screw cannot be adjusted; A58Textile Testing Instruments, Testing Equipment Manufacturer


7. If there is an electrical error, the device does not start, the indicator light does not light up and the display does not show anythingA58Textile Testing Instruments, Testing Equipment Manufacturer


It can check whether the switch, fuse, filament and electrical components of the automatic thermal desorption instrument are leaking or not making good contact. This can be checked by measuring the resistance, voltage and current signals and by replacing the original components if in doubt. A58Textile Testing Instruments, Testing Equipment Manufacturer
