In the use of transformer oil chromatography analyzer for chromatographic analysis of transformer oil,sampling this process directly determines the analysis effect,so before the operation should pay special attention to the matters needing attention when sampling,and today to please intelligent star about the details of the influence of sampling,let us do a reference.
A,whatever the type of transformer oil chromatographic analyzer,at the time of sampling sampling requirements must pay attention to,first of all,to be performed on the container operations,washed with distilled water or deionized water,and then clean with cleaning ethanol for container,and will be used in the oven to dry,there is a kind of method is also ensure the accuracy of the results of the analysis,That is to wash directly with water samples,but take samples immediately after washing.
Second,in the use of transformer oil chromatographic analyzer,pay attention to the sampling pipe must be with insulating oil produces chemical reaction,and has strong wear resistance,or you need to be replaced regularly sampling tube,and the material of the sampling pipe can't insulating oil catalytic effect,and also should pass before use of cleaning cleaning,such as ethanol You can also use distilled water and dry it.
Three,when the use of sampling tube in the oil drum sampling,but also pay attention to is to avoid the above oil,as far as possible by sampling,and found or suspected that there is free water in the oil,it is recommended to sample deep at the bottom,which is undoubtedly rigorous,but also after sampling to consider the cleaning of the sampling valve.This is for fear that the residual oil in the sampling valve will enter the sampling pipe and contaminate the sample,so these details should be observed.
Just mentioned is the use of transformer oil chromatography analyzer analysis,sampling process need to pay attention to the place,in fact,the whole sampling process should pay attention to the sample is not polluted,so usually to develop good operation habits,here it is recommended to refer to the equipment with the drug specification to sample,to ensure the results of analysis.
