Mercury is recognized as an element of global concern due to its long-range transport in the atmosphere, its persistence in the environment, its ability to bio-accumulate in ecosystems and its
negative effect on human health and the environment. Mercury can produce a range of adverse human health effects, including permanent damage to the nervous system, in particular the developing nervous system. Due to these effects, and also because mercury can be passed from a mother to her unborn child, infants, children and women of child bearing age are considered vulnerable populations. Mercury is absorbed into the human body through 3 primary paths̶ inhalation, ingestion and dermal absorption. Studies show as much as 75% of the inhaled mercury vapor may be retained in the human body which causes neurological toxicity.Today, most people are more aware of the dangers of mercury and many of its uses have been discontinued. However, mercury exposure is still an occupational hazard for people in many industries and mercury is present in the environment around us in areas such as the oil & gas sectors, gold mining, dental amalgams, fluorescent lamp production, etc.

Most traditional measuring method requires the mercury to be trapped into an absorbing solution or solid media collector and carefully transferred back to laboratory for pretreatment and analysis. The drawback of these methods is clearly their inability to provide the instant on-site/field results, thus delaying the decision to take necessary actions to prevent further exposure, evacuation and clean-up. To address this issue, the NIC EMP-2 offers on-site measurement of mercury vapor concentration in a real-time basis, even allowing tracking to the source of contamination. In operation, the EMP-2 draws the sample gas directly into the absorption cell and employs Ultra-Violet (UV) Atomic Absorption Spectroscopy (AAS) method to determine the mercury concentration at a specific wavelength of 253.7nm. The UV atomic absorption spectroscopy technique is superior in selectivity over most goldsensor/film resistance techniques that are commonly affected by humidity and temperature variation. Moreover, presence of acid gases will rapidly deteriorate the gold sensor which needs re-generation and factory calibration. The EMP-2 is not impacted by acid gases up to extraordinarily high levels.
How to measure the mercury?
