Causes And Solutions For Insufficient Sulfur Dioxide Standard Gas In The Whole Calibration Test

During the whole process calibration, many people will find that the sulfur dioxide standard gas test does not meet the technical indicators. Then, will this phenomenon have a great impact on our use? What causes this result? What methods can be used to quickly and effectively solve this result? I believe that many people still don’t know much about it. I have consulted the information in detail for this phenomenon in the past few days. I hope that the knowledge explained below can help everyone.

1. First of all, the common causes of this phenomenon.

There are five main reasons for the large error of sulfur dioxide standard gas. First of all, the first aspect is the problem of personal operation. As we all know, the operation of standard gas now requires some professional personnel who hold professional qualifications to operate. This is because, in addition to detecting and correcting the values for us, and bringing a lot of convenience to our daily life, if used improperly, it will also bring us certain harm. Therefore, in addition to taking corresponding protective measures, it is recommended that professional talents should operate it to avoid many errors during the operation and ensure the safety of the operator. If some personnel who are not very skilled in technology operate it, it may cause problems in desulfurization and denitrification control, resulting in low data.

2. Secondly, the second common reason is the problem between various equipment. For example, it is a problem with the sampling probe. It may be due to the sampling probe being too dry, or it may be due to the accumulation of some dust in the sampling probe, which leads to poor permeability, or it may be due to the inappropriate temperature of the sampling probe. Or it may be a problem with the pipeline. It may be due to the pipeline being too long or due to the problem of pipeline heating, which leads to the deviation of the value. It may also be due to the problem of pretreatment. The so-called pretreatment is the treatment process before the formal operation. It may be that during the pretreatment, there are some problems with the refrigerator, filter and pipeline, which leads to errors. Finally, it may be a problem with the analyzer. It may be some settings of the analyzer that lead to errors.

3. Finally, I will introduce solutions to common faults.

First of all, for problems with human operation, it is recommended that you try to choose professional operators who are familiar with the entire process of operation, will not make some low-level mistakes, and can ensure that each step is completed proficiently. Secondly, regarding the temperature of the sampling probe, it is recommended that you have a specific understanding of the temperature, direction, and humidity of the sampling probe, and adjust the appropriate values. At the same time, the filter element should be checked in advance before use. Thirdly, regarding the preheating problem, you should check whether there are any problems in various aspects of the pipeline before use to ensure that the temperature and humidity of the pipeline are appropriate and the location is appropriate. As for the pretreatment problem, it is recommended that you deal with the crystallization adsorption problem in advance. When you perform daily maintenance, you must pay attention to early detection so that you can solve the problem in time. Finally, regarding the analyzer problem, you must make accurate settings in advance.

I hope that the common problems raised today in the use of sulfur dioxide standard gas can attract your attention, and I also hope that the solutions I mentioned below will be useful to you.
