Product Description

The product conforms to Q / wth 33-2016 th-9300 pollution source mercury sampler (dust sampler); EPA 30b activated carbon adsorption tube method is used to determine the total gaseous mercury emission in coal-fired pollutants.


Features

  • The background of mercury content is very low, less than 5ng / g, which will not interfere with low concentration data;
  • The adsorption capacity is large, the capture efficiency is high, and it is difficult to penetrate due to high mercury background;
  • It can be applied to high flow sampling to ensure that the sampling equipment will not cause pressure loss due to adsorbent filling, effectively avoid pump overload under negative flue pressure, and ensure continuous and stable sampling flow;
  • In the high temperature and humidity field conditions, it can also ensure a good capture rate and data is not disturbed;
  • The two ends of the adsorption tube are provided with sealing sleeve, which can resist high temperature and low temperature, and effectively ensure that the activated carbon is not polluted by the outside world;
  • With a unique number, it is easy to control the sampling analysis process;
  • The size is accurate, the length is 185mm, and the outer diameter is 10mm. It is widely used in various brands of mercury sampler;
  • Each adsorption tube is marked with installation indication arrow to facilitate connection with Mercury Sampling equipment on site;
  • The field penetration rate and the consistency of pairs of adsorption tubes can meet the requirements of EPA method 30b.


Scope Of Application

The mercury adsorption tube is used to collect total gaseous mercury (including elemental mercury and oxidized mercury) in accordance with EPA method 30b. The total gaseous mercury can be collected with th-9300 mercury sampler and th-9310 atmospheric mercury sampler in the air. Mercury adsorption tube is one of the important components of the method for measuring the total mercury content in gaseous state. Mercury adsorption tube can add different amount of internal standard according to customer requirements, and the range of addition is (10-50000) ng.
