Precise instruments such as gas chromatographs require frequent maintenance. For many years engineers have revealed the secrets of chromatographic industry maintenance for you. Chromatography has more use value in many industries. So far, it has been more widely used in biochemistry, fire investigation, petroleum, food industry, chemical industry, medicine and health, and environmental protection. When such precision instruments are used, besides quantitative and qualitative analysis, they can also be used to perform activity coefficients, determine the partition coefficient of the sample on the stationary phase, and determine the physical-chemical constants of the molecular weight surface area. Here, we briefly talk about the maintenance knowledge of the gas chromatograph.
First, the gas chromatograph should do internal purging and cleaning
After the gas chromatograph was discontinued, we had to open the side and rear panels of the equipment, and then use instrument air and nitrogen to purge the dust from the open GC. If you use such a method to achieve the purpose of cleaning, that is, when there is more dust inside, using such a method is not to achieve the purpose of cleaning and cleaning. At this time, we can use the soft brush Clean up, but be aware that cleaning efforts must be lighter.
Second, pay attention to the maintenance and cleaning of the circuit board
When we do the inspection of the gas chromatograph, the first thing to do is to cut off the power supply of the instrument. In fact, the method is basically the same as the method described above. It is also done using the instrument air and nitrogen. Purging, for the more dusty parts, we also need to use a soft brush to clean up. However, it should be noted that during the operation, gloves must be worn so that static electricity can be avoided more effectively and sweat on the hands can be prevented from eroding the circuit board.
When using the gas chromatograph, it must be well maintained so that it can be used better and extend the life of the product.
