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The sample is thermally desorbed into a large syringe, then the sample is manually withdrawn and injected for gas chromatographic analysis.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


Automatic thermal desorption equipment mainly consists of:FiVTextile Testing Instruments, Testing Equipment Manufacturer


desorption activation treatment furnace, large constant temperature syringe heating furnace, double temperature controller, manual operation four parts composition. FiVTextile 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 and syringe heater to achieve the purpose of a multi-function machine;FiVTextile Testing Instruments, Testing Equipment Manufacturer


Therefore, compared to the previous similar desorption device, it has simplified operation, improved work efficiency and analysis accuracy.

The carmatic thermal desorption device adopts the integrated design of absorption activation treatment furnace and large constant temperature syringe heating furnace. One machine has multiple functions, greatly improving the cost performance and running cost of the automatic thermal desorption device; FiVTextile Testing Instruments, Testing Equipment Manufacturer


The same sample can be injected repeatedly, avoiding the adverse effects caused by misoperation during sample injection or analysis;FiVTextile Testing Instruments, Testing Equipment Manufacturer


At of the measurement, you can use cheap activated carbon adsorption tubes, etc.FiVTextile Testing Instruments, Testing Equipment Manufacturer


Compared with domestic thermal desorption instruments (devices), the installation of desorption tubes is simple, and no dead volume operation is realized;FiVTextile Testing Instruments, Testing Equipment Manufacturer


The automatic thermal desorption device is especially suitable for beginners who are unfamiliar with chromatographic analysis. FiVTextile Testing Instruments, Testing Equipment Manufacturer


That automaticallye thermal desorption equipment needs maintenance after a period of use to ensure the normal operation of its subsequent work and prolong its service life. FiVTextile Testing Instruments, Testing Equipment Manufacturer


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


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


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


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


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


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


6. The mechanical system has crashed, slipped, vibrated, caused by wear, rust, dust, oil, breakage, damage, falling into foreign objects, looseness or improper operation. The operation is not synchronous and the lead screw cannot be adjusted;FiVTextile Testing Instruments, Testing Equipment Manufacturer


The sound temperature is abnormal, which can be verified by various means such as observation, hearing, measurement and touch. FiVTextile Testing Instruments, Testing Equipment Manufacturer


7. If there is an electrical error, the device will not start, the indicator light will not light up and the display will not show anythingFiVTextile 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, and can the resistanceMeasure and replace voltage, current and voltage signals. Please contact the original device concerned for troubleshooting. FiVTextile Testing Instruments, Testing Equipment Manufacturer
