Mercury analyzer consumables - sampling tube

The adsorption medium in the sampling tube consists of at least two sections, each of which can be analyzed independently. The first paragraph is the analysis section, used for adsorbing gaseous mercury in flue gas; The second section is a backup section used to capture gaseous mercury that penetrates the first section; Fill inert materials such as glass wool or quartz wool between the two sections. When sampling, two activated carbon adsorption tubes with dual channels are usually set up in parallel at the inlet sampling probe section for simultaneous sampling. On the one hand, two sets of data can be obtained in one measurement, reducing sampling time, and on the other hand, the accuracy of a single measurement can be judged.
