In combination with EMP-3 and Gold+, makes you on-site measurement as High-Sensitivity Mercury Analyzer.
On-site measurement realized by its integrating the detector and mercury trap into the case
The EMP Gold+ is a portable mercury analyzer using the gold amalgam concentration atomic absorption spectrometry.
By attaching the Gold+ unit to the EMP-3, it is possible to make the sensitivity 1,000 times as high and measure air in the general environment.
Principle of measurement (measurement of air in general environment)
Sampling is carried out with the heater kept at 150°C to suppress the influence of interference gas. The mercury in the gas in the sample is collected and concentrated as gold amalgam in the mercury collector tube. After the collection, the mercury collector tube is heated to separate mercury gas, a measurement is made using the atomic absorption spectrometry, and the result is converted into the quantity of mercury.
The sampled gas quantity is measured as an air quantity in standard conditions (0°C and 1 atm.) using the flow sensor, and a mercury concentration is automatically calculated.
Various options enable measurement of mercury in natural gas, liquefied petroleum gas, and low-concentration solutions
When you connect a Gold+ unit gas meter (optional), natural gas or liquefied petroleum gas can be available for measurement.
Also, by connecting the AQUA kit (reduced vaporized mercury measurement option), it is possible to measure extremely low concentrations of mercury in a solution.
